DrJava / Support Requests / #318 After install can't find compiler after setting up Edit-->preferences my adrs-flamed@optonline.net

Robert Cartwright - 2015-10-05

Hi Chris,

I apologize for missing your email; I did not notice it until Charles Reis
sent me a heads up message to look for it in my email archive (which
contains 40,000 messages).

I notice that you are using an old version of DrJava (from 2008) with Java
8. Only the latest release of DrJava (drjava-stable-20140826-r5761) supports
Java 8. The configuration of tools.jar is slightly different in every
release of Java up to Java 7 and requires a different adapter which DrJava
automatically loads. But old versions of DrJava do not include adapters
for later versions of Java. In 2008, DrJava supported Java 5 and Java 6.

I originally thought the next to last release of DrJava worked for Java 8,
but the Java 7 adapter (which otherwise works for Java 8) checked for a
Java 7 specific field in a class in tools.jar which of course is not
present in Java 8. The latest release eliminates this check. Since
Sun/Oracle standardized the API for tools.jar in Java 7 (most of the
standardization was done in Java 6 but Sun/Oracle did not get the
implementation right until Java 7), all future releases of the Java JDK
should work assuming Oracle continues to support backward compatibility
(running legacy programs on the newest JVM).

I do NOT recommend selecting a specific tools.jar in DrJava preferences. I
don't think anyone at Rice has used that feature in several years. DrJava
searches for tools.jar in all of the logical places on Windows, Linux, and
Mac OS X. I am not aware of any cases where the latest release of DrJava
fails to find a tools.jar file for Java 6, 7, or 8 provided that the
tools.jar file is installed in the default location (chosen by the JDK
distribution) and no tools.jar preference is set. On my Ubuntu Linux
machine, DrJava finds six different tools.jar files: openJDK and Oracle
versions of Java 6, 7, and 8. I had to download the Java 8 openJDK from
Azul Systems since it does not appear to be available on any of the
standard Ubuntu Linux repositories. (The Oracle Java 8 JDK works well; I
downloaded openJDK 8 because it is open source which means we can
incorporate binary code from openJDK 8--such as tools.jar--in DrJava if
necessary. We currently include an open source Eclipse compiler (ecj) but
recently looked at including javac from openJDK 8 instead. (Some DrJava
users try to use DrJava with only a Java JRE (no tools.jar) installed on
their machines.) After downloading the latest release of DrJava, please
delete all entries you have set regarding tools.jar and class paths in your
drjava preferences file. The defaults generally work well with one
exception: DrJava does not include the "peripheral" jar libraries (notably
javafx) located in jre/lib/ext in Java 8 in the class path; you must add
these jar files to the classpath if you want to use them.

Please try downloading the latest release of DrJava and removing your
tools.jar entry in the drjava preferences file and let me know what
happens. To be certain I see your email, send it to corky.cartwright AT
gmail.com.

Best,

Robert "Corky" Cartwright

I downloaded the DrJava product and it looks very good for what it should do. Sadly it isn’t doing what it should based on the instructions at SourceForge. I have located the compiler that I installed, and it seems to be OK, but I wouldn’t know what it should look like. I pointed the DrJava to the compiler ‘tools.jar’ in the ‘lib’ folder of the compiler group. I used the Edit preferences dialog box to point to the ‘tools.jar’ location. No matter what I do I still get ‘compiler: none’ message. I checked the .drjava file and the data I put in for the compiler location is there, so the edit preferences worked fine, but still no compiler. I also didn’t see any ‘javac.exe’ in the files in the ‘tools.jar’ group. I don’t know if there should be. My system is Windows 7 with 3 gb memory and plenty of disk space. I’ve tried to download DrJava with the normal selection from the SourceForge site, but I always get a registry error. I cleaned the registry, but get the error anyway, and the download fails. When I forced the download to use a mirror site and I downloaded the RICE version of DrJava, it was downloaded correctly, but there was no compiler with the product, and so I’m stuck trying to somehow get it to recognize the compiler and use it.

Support Requests: #318

  Robert,
  
  Thank you for replying to my request. I thought for a while there that no one was alive any longer at DrJava. Part of my problem is that I downloaded the latest release of DrJava, or what I believe to be the latest from the possible clickables at the SourceForge site and it failed many times. I got messages as soon as it tried to bring up the package, and it never was able to completely bring it up. There was a point early on in my problems where I was able to download a version of DrJava and it came with a compiler right in the package and it was able to load up, but I wanted the latest compiler and that didn’t seem to be it, and then I was unable to make anything I loaded work. When I download the ‘latest’ file from the choices (there are a few different ‘latest’ to choose from, both labeled ‘stable’) I get the following message in a dialog box:
  
  “The registry refers to a nonexistent Java Runtime Environment installation or the runtime is corrupted.
  
  The system can't find the path specified.”
  
  I just now tried the ‘standard’ download again, and got the message as before.
  
  That caused me to go to a mirror site which turned out to be featuring the ‘Rice’ version. Then the version worked and loaded up, but pointed at no compiler. Now I can remove the pointer in .drjava to the tools.jar file, but what is the problem with this silly thing with the message I mentioned above? Have you seen that before?
  
  I really think the DrJava is the environment that is right for me to use, if at all possible.

    Hi Chris,
    
    DO NOT POINT DRJAVA to a tools.jar file! In the absence of such a
    preference, DrJava will automatically find tools.jar provided that you have
    installed a Java 6,7, or 8 JDK in the default location. If you set the
    DrJava preferences to point to a specific tools.jar file, you must deeply
    understand how DrJava works. I have not set that preference in my drjava
    profile in the last 8-9 years. Nearly a decade ago, the DrJava development
    team added DrJava support for finding tools.jar in any reasonable location
    in a Windows, Mac OS X, or LInus file system. Since that time, I don't
    anyone on development team who has configured DrJava to find tools.jar in a
    specific location. Even if it works temporarily, it will break when you
    upgrade the Java JDK.
    
    You need to uninstall all Java JRE's and JDK's on your machine, delete you
    .drjava preferences file (in your home directory), and then download and
    install the latest Oracle JDK 8. Install the JDK in the default location
    so DrJava can easily find the tools.jar file. A Java JDK download includes
    a JRE installation plus several additional files including tools.jar with a
    compiler (and a debugging framework and javadoc). tools.jar DOES NOT
    CONTAIN a java.exe file, which is part of a JRE installation. We are
    legally prohibited from including a JDK compiler (in tools.jar) in DrJava
    because it is proprietary; Oracle owns it. If you install the Java JRE
    (but not the JDK), the combined Java/DrJava installation does not include a
    tools.jar file and hence no Oracle Java compiler has been installed.
    Nevertheless, DrJava includes a bundled open source Eclipse Java compiler
    which you should see inside DrJava if no tools.jar file can be found. The
    fact that you are seeing "no compiler" indicates that something is terribly
    wrong with your Java configuration.
    
    It sounds to me like you are having problems installing Java, either in JDK
    [strongly preferred] or JRE only form. Installing DrJava will not fix and
    cannot fix problems in a Java installation. DrJava augments a Java JDK,
    which supports a simple but tedious command line interface. If you follow
    my instructions and DrJava still does not work, you need to confirm that
    Java works from the command line by creating a simple Java program such as
    the familiar program that prints "Hello World!". I am sure that you can
    find copies of such a program on the internet (perhaps as the "main" method
    of a class called HelloWorld). If java is installed correctly, you should
    be able to compile the HelloWorld! program from the command line (after
    creating it using a text editor like WordPad) by typing
    
    javac HelloWorld.java
    
    (assuming the file containing the program is called "HelloWorld.java") and
    then typing
    
    java HelloWorld
    
    (assuming that the main method of class HelloWorld prints "HelloWorld!") to
    run the program.
    
    In Windows, the command line is accessed using the "Command Prompt" program
    on the start menu.
    
    Best,
    
    Corky Cartwright
    
    P.S. DrJava is no longer funded by any federal agency or corporation; the
    support staff now consists of one member: me. I receive no compensation
    for providing support for DrJava.

    Robert,
    
    Thank you for replying to my request. I thought for a while there that no one was alive any longer at DrJava. Part of my problem is that I downloaded the latest release of DrJava, or what I believe to be the latest from the possible clickables at the SourceForge site and it failed many times. I got messages as soon as it tried to bring up the package, and it never was able to completely bring it up. There was a point early on in my problems where I was able to download a version of DrJava and it came with a compiler right in the package and it was able to load up, but I wanted the latest compiler and that didn’t seem to be it, and then I was unable to make anything I loaded work.
    
    When I download the ‘latest’ file from the choices (there are a few different ‘latest’ to choose from, both labeled ‘stable’) I get the following message in a dialog box:
    
    “The registry refers to a nonexistent Java Runtime Environment
    installation or the runtime is corrupted.
    
    The system can't find the path specified.”
    
    I just now tried the ‘standard’ download again, and got the message as
    before.
    
    That caused me to go to a mirror site which turned out to be featuring the
    ‘Rice’ version. Then the version worked and loaded up, but pointed at no
    compiler. Now I can remove the pointer in .drjava to the tools.jar file,
    but what is the problem with this silly thing with the message I mentioned
    above? Have you seen that before?
    
    I really think the DrJava is the environment that is right for me to use,
    if at all possible.

    Hi Chris,
    
    I apologize for missing your email; I did not notice it until Charles Reis
    sent me a heads up message to look for it in my email archive (which
    contains 40,000 messages).
    
    I notice that you are using an old version of DrJava (from 2008) with Java
    8. Only the latest release of DrJava (drjava-stable-20140826-r5761)
    supports
    Java 8. The configuration of tools.jar is slightly different in every
    release of Java up to Java 7 and requires a different adapter which DrJava
    automatically loads. But old versions of DrJava do not include adapters
    for later versions of Java. In 2008, DrJava supported Java 5 and Java 6.
    
    I originally thought the next to last release of DrJava worked for Java 8,
    but the Java 7 adapter (which otherwise works for Java 8) checked for a
    Java 7 specific field in a class in tools.jar which of course is not
    present in Java 8. The latest release eliminates this check. Since
    Sun/Oracle standardized the API for tools.jar in Java 7 (most of the
    standardization was done in Java 6 but Sun/Oracle did not get the
    implementation right until Java 7), all future releases of the Java JDK
    should work assuming Oracle continues to support backward compatibility
    (running legacy programs on the newest JVM).
    
    I do NOT recommend selecting a specific tools.jar in DrJava preferences. I
    don't think anyone at Rice has used that feature in several years. DrJava
    searches for tools.jar in all of the logical places on Windows, Linux, and
    Mac OS X. I am not aware of any cases where the latest release of DrJava
    fails to find a tools.jar file for Java 6, 7, or 8 provided that the
    tools.jar file is installed in the default location (chosen by the JDK
    distribution) and no tools.jar preference is set. On my Ubuntu Linux
    machine, DrJava finds six different tools.jar files: openJDK and Oracle
    versions of Java 6, 7, and 8. I had to download the Java 8 openJDK from
    Azul Systems since it does not appear to be available on any of the
    standard Ubuntu Linux repositories. (The Oracle Java 8 JDK works well; I
    downloaded openJDK 8 because it is open source which means we can
    incorporate binary code from openJDK 8--such as tools.jar--in DrJava if
    necessary. We currently include an open source Eclipse compiler (ecj) but
    recently looked at including javac from openJDK 8 instead. (Some DrJava
    users try to use DrJava with only a Java JRE (no tools.jar) installed on
    their machines.) After downloading the latest release of DrJava, please
    delete all entries you have set regarding tools.jar and class paths in your
    drjava preferences file. The defaults generally work well with one
    exception: DrJava does not include the "peripheral" jar libraries (notably
    javafx) located in jre/lib/ext in Java 8 in the class path; you must add
    these jar files to the classpath if you want to use them.
    
    Please try downloading the latest release of DrJava and removing your
    tools.jar entry in the drjava preferences file and let me know what
    happens. To be certain I see your email, send it to corky.cartwright AT
    gmail.com.
    
    Best,
    
    Robert "Corky" Cartwright

    I downloaded the DrJava product and it looks very good for what it should do. Sadly it isn’t doing what it should based on the instructions at SourceForge. I have located the compiler that I installed, and it seems to be OK, but I wouldn’t know what it should look like. I pointed the DrJava to the compiler ‘tools.jar’ in the ‘lib’ folder of the compiler group. I used the Edità preferences dialog box to point to the ‘tools.jar’ location. No matter what I do I still get ‘compiler: none’ message. I checked the .drjava file and the data I put in for the compiler location is there, so the edità preferences worked fine, but still no compiler. I also didn’t see any ‘javac.exe’ in the files in the ‘tools.jar’ group. I don’t know if there should be. My system is Windows 7 with 3 gb memory and plenty of disk space. I’ve tried to download DrJava with the normal selection from the SourceForge site, but I always get a registry error. I cleaned the registry, but get the error anyway, and the download fails. When I forced the download to use a mirror site and I downloaded the RICE version of DrJava, it was downloaded correctly, but there was no compiler with the product, and so I’m stuck trying to somehow get it to recognize the compiler and use it.

    I downloaded the DrJava product and it looks very good for what it should do. Sadly it isn’t doing what it should based on the instructions at SourceForge. I have located the compiler that I installed, and it seems to be OK, but I wouldn’t know what it should look like. I pointed the DrJava to the compiler ‘tools.jar’ in the ‘lib’ folder of the compiler group. I used the Edit preferences dialog box to point to the ‘tools.jar’ location. No matter what I do I still get ‘compiler: none’ message. I checked the .drjava file and the data I put in for the compiler location is there, so the edit preferences worked fine, but still no compiler. I also didn’t see any ‘javac.exe’ in the files in the ‘tools.jar’ group. I don’t know if there should be. My system is Windows 7 with 3 gb memory and plenty of disk space.

      I’m sorry to hear that there is no funding for a language that can be used almost anywhere. As to your insisting on me not pointing to the tools.jar file, I already got that note and have removed the reference in my .drjava file. To help you with your debugging, I installed the JDK as per instructions and did nothing out of standard based on the instructions available. I will try to delete everything I already downloaded and start fresh as per your instructions and will let you know what the results are.

      Hi Chris,
      
      DO NOT POINT DRJAVA to a tools.jar file! In the absence of such a
      preference, DrJava will automatically find tools.jar provided that you have
      installed a Java 6,7, or 8 JDK in the default location. If you set the
      DrJava preferences to point to a specific tools.jar file, you must deeply
      understand how DrJava works. I have not set that preference in my drjava
      profile in the last 8-9 years. Nearly a decade ago, the DrJava development
      team added DrJava support for finding tools.jar in any reasonable location
      in a Windows, Mac OS X, or LInus file system. Since that time, I don't
      anyone on development team who has configured DrJava to find tools.jar in a
      specific location. Even if it works temporarily, it will break when you
      upgrade the Java JDK.
      
      You need to uninstall all Java JRE's and JDK's on your machine, delete you
      .drjava preferences file (in your home directory), and then download and
      install the latest Oracle JDK 8. Install the JDK in the default location
      so DrJava can easily find the tools.jar file. A Java JDK download includes
      a JRE installation plus several additional files including tools.jar with a
      compiler (and a debugging framework and javadoc). tools.jar DOES NOT
      CONTAIN a java.exe file, which is part of a JRE installation. We are
      legally prohibited from including a JDK compiler (in tools.jar) in DrJava
      because it is proprietary; Oracle owns it. If you install the Java JRE
      (but not the JDK), the combined Java/DrJava installation does not include a
      tools.jar file and hence no Oracle Java compiler has been installed.
      Nevertheless, DrJava includes a bundled open source Eclipse Java compiler
      which you should see inside DrJava if no tools.jar file can be found. The
      fact that you are seeing "no compiler" indicates that something is terribly
      wrong with your Java configuration.
      
      It sounds to me like you are having problems installing Java, either in JDK
      [strongly preferred] or JRE only form. Installing DrJava will not fix and
      cannot fix problems in a Java installation. DrJava augments a Java JDK,
      which supports a simple but tedious command line interface. If you follow
      my instructions and DrJava still does not work, you need to confirm that
      Java works from the command line by creating a simple Java program such as
      the familiar program that prints "Hello World!". I am sure that you can
      find copies of such a program on the internet (perhaps as the "main" method
      of a class called HelloWorld). If java is installed correctly, you should
      be able to compile the HelloWorld! program from the command line (after
      creating it using a text editor like WordPad) by typing
      
      javac HelloWorld.java
      
      (assuming the file containing the program is called "HelloWorld.java") and
      then typing
      
      java HelloWorld
      
      (assuming that the main method of class HelloWorld prints "HelloWorld!") to
      run the program.
      
      In Windows, the command line is accessed using the "Command Prompt" program
      on the start menu.
      
      Best,
      
      Corky Cartwright
      
      P.S. DrJava is no longer funded by any federal agency or corporation; the
      support staff now consists of one member: me. I receive no compensation
      for providing support for DrJava.

      Robert,
      
      Thank you for replying to my request. I thought for a while there that no one was alive any longer at DrJava. Part of my problem is that I downloaded the latest release of DrJava, or what I believe to be the latest from the possible clickables at the SourceForge site and it failed many times. I got messages as soon as it tried to bring up the package, and it never was able to completely bring it up. There was a point early on in my problems where I was able to download a version of DrJava and it came with a compiler right in the package and it was able to load up, but I wanted the latest compiler and that didn’t seem to be it, and then I was unable to make anything I loaded work.
      
      When I download the ‘latest’ file from the choices (there are a few different ‘latest’ to choose from, both labeled ‘stable’) I get the following message in a dialog box:
      
      “The registry refers to a nonexistent Java Runtime Environment
      installation or the runtime is corrupted.
      
      The system can't find the path specified.”
      
      I just now tried the ‘standard’ download again, and got the message as
      before.
      
      That caused me to go to a mirror site which turned out to be featuring the
      ‘Rice’ version. Then the version worked and loaded up, but pointed at no
      compiler. Now I can remove the pointer in .drjava to the tools.jar file,
      but what is the problem with this silly thing with the message I mentioned
      above? Have you seen that before?
      
      I really think the DrJava is the environment that is right for me to use,
      if at all possible.

      Hi Chris,
      
      I apologize for missing your email; I did not notice it until Charles Reis
      sent me a heads up message to look for it in my email archive (which
      contains 40,000 messages).
      
      I notice that you are using an old version of DrJava (from 2008) with Java
      8. Only the latest release of DrJava (drjava-stable-20140826-r5761)
      supports
      Java 8. The configuration of tools.jar is slightly different in every
      release of Java up to Java 7 and requires a different adapter which DrJava
      automatically loads. But old versions of DrJava do not include adapters
      for later versions of Java. In 2008, DrJava supported Java 5 and Java 6.
      
      I originally thought the next to last release of DrJava worked for Java 8,
      but the Java 7 adapter (which otherwise works for Java 8) checked for a
      Java 7 specific field in a class in tools.jar which of course is not
      present in Java 8. The latest release eliminates this check. Since
      Sun/Oracle standardized the API for tools.jar in Java 7 (most of the
      standardization was done in Java 6 but Sun/Oracle did not get the
      implementation right until Java 7), all future releases of the Java JDK
      should work assuming Oracle continues to support backward compatibility
      (running legacy programs on the newest JVM).
      
      I do NOT recommend selecting a specific tools.jar in DrJava preferences. I
      don't think anyone at Rice has used that feature in several years. DrJava
      searches for tools.jar in all of the logical places on Windows, Linux, and
      Mac OS X. I am not aware of any cases where the latest release of DrJava
      fails to find a tools.jar file for Java 6, 7, or 8 provided that the
      tools.jar file is installed in the default location (chosen by the JDK
      distribution) and no tools.jar preference is set. On my Ubuntu Linux
      machine, DrJava finds six different tools.jar files: openJDK and Oracle
      versions of Java 6, 7, and 8. I had to download the Java 8 openJDK from
      Azul Systems since it does not appear to be available on any of the
      standard Ubuntu Linux repositories. (The Oracle Java 8 JDK works well; I
      downloaded openJDK 8 because it is open source which means we can
      incorporate binary code from openJDK 8--such as tools.jar--in DrJava if
      necessary. We currently include an open source Eclipse compiler (ecj) but
      recently looked at including javac from openJDK 8 instead. (Some DrJava
      users try to use DrJava with only a Java JRE (no tools.jar) installed on
      their machines.) After downloading the latest release of DrJava, please
      delete all entries you have set regarding tools.jar and class paths in your
      drjava preferences file. The defaults generally work well with one
      exception: DrJava does not include the "peripheral" jar libraries (notably
      javafx) located in jre/lib/ext in Java 8 in the class path; you must add
      these jar files to the classpath if you want to use them.
      
      Please try downloading the latest release of DrJava and removing your
      tools.jar entry in the drjava preferences file and let me know what
      happens. To be certain I see your email, send it to corky.cartwright AT
      gmail.com.
      
      Best,

      I downloaded the DrJava product and it looks very good for what it should do. Sadly it isn’t doing what it should based on the instructions at SourceForge. I have located the compiler that I installed, and it seems to be OK, but I wouldn’t know what it should look like. I pointed the DrJava to the compiler ‘tools.jar’ in the ‘lib’ folder of the compiler group. I used the Edità preferences dialog box to point to the ‘tools.jar’ location. No matter what I do I still get ‘compiler: none’ message. I checked the .drjava file and the data I put in for the compiler location is there, so the edità preferences worked fine, but still no compiler. I also didn’t see any ‘javac.exe’ in the files in the ‘tools.jar’ group. I don’t know if there should be.
      
      My system is Windows 7 with 3 gb memory and plenty of disk space.
      
      I’ve tried to download DrJava with the normal selection from the SourceForge site, but I always get a registry error. I cleaned the registry, but get the error anyway, and the download fails. When I forced the download to use a mirror site and I downloaded the RICE version of DrJava, it was downloaded correctly, but there was no compiler with the product, and so I’m stuck trying to somehow get it to recognize the compiler and use it.

I’ve tried to download DrJava with the normal selection from the SourceForge site, but I always get a registry error. I cleaned the registry, but get the error anyway, and the download fails. When I forced the download to use a mirror site and I downloaded the RICE version of DrJava, it was downloaded correctly, but there was no compiler with the product, and so I’m stuck trying to somehow get it to recognize the compiler and use it.

      I downloaded the DrJava product and it looks very good for what it should do. Sadly it isn’t doing what it should based on the instructions at SourceForge. I have located the compiler that I installed, and it seems to be OK, but I wouldn’t know what it should look like. I pointed the DrJava to the compiler ‘tools.jar’ in the ‘lib’ folder of the compiler group. I used the Edità preferences dialog box to point to the ‘tools.jar’ location. No matter what I do I still get ‘compiler: none’ message. I checked the .drjava file and the data I put in for the compiler location is there, so the edità preferences worked fine, but still no compiler. I also didn’t see any ‘javac.exe’ in the files in the ‘tools.jar’ group. I don’t know if there should be. My system is Windows 7 with 3 gb memory and plenty of disk space. I’ve tried to download DrJava with the normal selection from the SourceForge site, but I always get a registry error. I cleaned the registry, but get the error anyway, and the download fails. When I forced the download to use a mirror site and I downloaded the RICE version of DrJava, it was downloaded correctly, but there was no compiler with the product, and so I’m stuck trying to somehow get it to recognize the compiler and use it.

      Robert,
      
      I followed your instructions and it appears to have worked. I tried a small class and it compiled and ran. I think I also deleted a number of Microsoft files that began with ‘Java’, you know files that may have come with Visual Studio and similar products. Time will tell if I try to run Java from their product base.
      
      Thanks for your help.

      Hi Chris,
      
      DO NOT POINT DRJAVA to a tools.jar file! In the absence of such a
      preference, DrJava will automatically find tools.jar provided that you have
      installed a Java 6,7, or 8 JDK in the default location. If you set the
      DrJava preferences to point to a specific tools.jar file, you must deeply
      understand how DrJava works. I have not set that preference in my drjava
      profile in the last 8-9 years. Nearly a decade ago, the DrJava development
      team added DrJava support for finding tools.jar in any reasonable location
      in a Windows, Mac OS X, or LInus file system. Since that time, I don't
      anyone on development team who has configured DrJava to find tools.jar in a
      specific location. Even if it works temporarily, it will break when you
      upgrade the Java JDK.
      
      You need to uninstall all Java JRE's and JDK's on your machine, delete you
      .drjava preferences file (in your home directory), and then download and
      install the latest Oracle JDK 8. Install the JDK in the default location
      so DrJava can easily find the tools.jar file. A Java JDK download includes
      a JRE installation plus several additional files including tools.jar with a
      compiler (and a debugging framework and javadoc). tools.jar DOES NOT
      CONTAIN a java.exe file, which is part of a JRE installation. We are
      legally prohibited from including a JDK compiler (in tools.jar) in DrJava
      because it is proprietary; Oracle owns it. If you install the Java JRE
      (but not the JDK), the combined Java/DrJava installation does not include a
      tools.jar file and hence no Oracle Java compiler has been installed.
      Nevertheless, DrJava includes a bundled open source Eclipse Java compiler
      which you should see inside DrJava if no tools.jar file can be found. The
      fact that you are seeing "no compiler" indicates that something is terribly
      wrong with your Java configuration.
      
      It sounds to me like you are having problems installing Java, either in JDK
      [strongly preferred] or JRE only form. Installing DrJava will not fix and
      cannot fix problems in a Java installation. DrJava augments a Java JDK,
      which supports a simple but tedious command line interface. If you follow
      my instructions and DrJava still does not work, you need to confirm that
      Java works from the command line by creating a simple Java program such as
      the familiar program that prints "Hello World!". I am sure that you can
      find copies of such a program on the internet (perhaps as the "main" method
      of a class called HelloWorld). If java is installed correctly, you should
      be able to compile the HelloWorld! program from the command line (after
      creating it using a text editor like WordPad) by typing
      
      javac HelloWorld.java
      
      (assuming the file containing the program is called "HelloWorld.java") and
      then typing
      
      java HelloWorld
      
      (assuming that the main method of class HelloWorld prints "HelloWorld!") to
      run the program.
      
      In Windows, the command line is accessed using the "Command Prompt" program
      on the start menu.
      
      Best,
      
      Corky Cartwright
      
      P.S. DrJava is no longer funded by any federal agency or corporation; the
      support staff now consists of one member: me. I receive no compensation
      for providing support for DrJava.

      Robert,
      
      Thank you for replying to my request. I thought for a while there that no one was alive any longer at DrJava. Part of my problem is that I downloaded the latest release of DrJava, or what I believe to be the latest from the possible clickables at the SourceForge site and it failed many times. I got messages as soon as it tried to bring up the package, and it never was able to completely bring it up. There was a point early on in my problems where I was able to download a version of DrJava and it came with a compiler right in the package and it was able to load up, but I wanted the latest compiler and that didn’t seem to be it, and then I was unable to make anything I loaded work.
      
      When I download the ‘latest’ file from the choices (there are a few different ‘latest’ to choose from, both labeled ‘stable’) I get the following message in a dialog box:
      
      “The registry refers to a nonexistent Java Runtime Environment
      installation or the runtime is corrupted.
      
      The system can't find the path specified.”
      
      I just now tried the ‘standard’ download again, and got the message as
      before.
      
      That caused me to go to a mirror site which turned out to be featuring the
      ‘Rice’ version. Then the version worked and loaded up, but pointed at no
      compiler. Now I can remove the pointer in .drjava to the tools.jar file,
      but what is the problem with this silly thing with the message I mentioned
      above? Have you seen that before?
      
      I really think the DrJava is the environment that is right for me to use,
      if at all possible.

      Hi Chris,
      
      I apologize for missing your email; I did not notice it until Charles Reis
      sent me a heads up message to look for it in my email archive (which
      contains 40,000 messages).
      
      I notice that you are using an old version of DrJava (from 2008) with Java
      8. Only the latest release of DrJava (drjava-stable-20140826-r5761)
      supports
      Java 8. The configuration of tools.jar is slightly different in every
      release of Java up to Java 7 and requires a different adapter which DrJava
      automatically loads. But old versions of DrJava do not include adapters
      for later versions of Java. In 2008, DrJava supported Java 5 and Java 6.
      
      I originally thought the next to last release of DrJava worked for Java 8,
      but the Java 7 adapter (which otherwise works for Java 8) checked for a
      Java 7 specific field in a class in tools.jar which of course is not
      present in Java 8. The latest release eliminates this check. Since
      Sun/Oracle standardized the API for tools.jar in Java 7 (most of the
      standardization was done in Java 6 but Sun/Oracle did not get the
      implementation right until Java 7), all future releases of the Java JDK
      should work assuming Oracle continues to support backward compatibility
      (running legacy programs on the newest JVM).
      
      I do NOT recommend selecting a specific tools.jar in DrJava preferences. I
      don't think anyone at Rice has used that feature in several years. DrJava
      searches for tools.jar in all of the logical places on Windows, Linux, and
      Mac OS X. I am not aware of any cases where the latest release of DrJava
      fails to find a tools.jar file for Java 6, 7, or 8 provided that the
      tools.jar file is installed in the default location (chosen by the JDK
      distribution) and no tools.jar preference is set. On my Ubuntu Linux
      machine, DrJava finds six different tools.jar files: openJDK and Oracle
      versions of Java 6, 7, and 8. I had to download the Java 8 openJDK from
      Azul Systems since it does not appear to be available on any of the
      standard Ubuntu Linux repositories. (The Oracle Java 8 JDK works well; I
      downloaded openJDK 8 because it is open source which means we can
      incorporate binary code from openJDK 8--such as tools.jar--in DrJava if
      necessary. We currently include an open source Eclipse compiler (ecj) but
      recently looked at including javac from openJDK 8 instead. (Some DrJava
      users try to use DrJava with only a Java JRE (no tools.jar) installed on
      their machines.) After downloading the latest release of DrJava, please
      delete all entries you have set regarding tools.jar and class paths in your
      drjava preferences file. The defaults generally work well with one
      exception: DrJava does not include the "peripheral" jar libraries (notably
      javafx) located in jre/lib/ext in Java 8 in the class path; you must add
      these jar files to the classpath if you want to use them.
      
      Please try downloading the latest release of DrJava and removing your
      tools.jar entry in the drjava preferences file and let me know what
      happens. To be certain I see your email, send it to corky.cartwright AT
      gmail.com.
      
      Best,
      
      Robert "Corky" Cartwright

      I downloaded the DrJava product and it looks very good for what it should do. Sadly it isn’t doing what it should based on the instructions at SourceForge. I have located the compiler that I installed, and it seems to be OK, but I wouldn’t know what it should look like. I pointed the DrJava to the compiler ‘tools.jar’ in the ‘lib’ folder of the compiler group. I used the Edità preferences dialog box to point to the ‘tools.jar’ location. No matter what I do I still get ‘compiler: none’ message. I checked the .drjava file and the data I put in for the compiler location is there, so the edità preferences worked fine, but still no compiler. I also didn’t see any ‘javac.exe’ in the files in the ‘tools.jar’ group. I don’t know if there should be.
      
      My system is Windows 7 with 3 gb memory and plenty of disk space.
      
      I’ve tried to download DrJava with the normal selection from the SourceForge site, but I always get a registry error. I cleaned the registry, but get the error anyway, and the download fails. When I forced the download to use a mirror site and I downloaded the RICE version of DrJava, it was downloaded correctly, but there was no compiler with the product, and so I’m stuck trying to somehow get it to recognize the compiler and use it.

      I downloaded the DrJava product and it looks very good for what it should do. Sadly it isn’t doing what it should based on the instructions at SourceForge. I have located the compiler that I installed, and it seems to be OK, but I wouldn’t know what it should look like. I pointed the DrJava to the compiler ‘tools.jar’ in the ‘lib’ folder of the compiler group. I used the Edità preferences dialog box to point to the ‘tools.jar’ location. No matter what I do I still get ‘compiler: none’ message. I checked the .drjava file and the data I put in for the compiler location is there, so the edità preferences worked fine, but still no compiler. I also didn’t see any ‘javac.exe’ in the files in the ‘tools.jar’ group. I don’t know if there should be. My system is Windows 7 with 3 gb memory and plenty of disk space. I’ve tried to download DrJava with the normal selection from the SourceForge site, but I always get a registry error. I cleaned the registry, but get the error anyway, and the download fails. When I forced the download to use a mirror site and I downloaded the RICE version of DrJava, it was downloaded correctly, but there was no compiler with the product, and so I’m stuck trying to somehow get it to recognize the compiler and use it.
