[Php-java-bridge-users] CLASSPATH once more

[Michael P. D. <dob...@we...>]

Dear Experts!

Yesterday I installed the Java-Bridge (ver. 2.0.4) and everything works fine
so far, but I'm struggling with JAR, CLASSPATH or whatever the problem
generates.

With PHP I call a Java-Class (UserClass1) stored in a JAR-file
(jarfile.jar). In PHP I "link" to this JAR file with:

java_set_library_path("/srv/www/htdocs/user/jarfile.jar").

In that JAR-File there is also a file (Data.File) stored, which is called by
another JAVA-Class (UserClass2) with java.net.JarURLConnection and
ClassLoader-Function. UserClass2 is called by UserClass1. 

This works fine by calling it direct with java (java -classpath jarfile.jar
UserClass1) but by using it with the Java-Bridge it does not work.
Here the UserClass2 can't find the Data.File. To get an idea, what's going
wrong, I inserted a further class (ShowResources.class)
(http://forum.java.sun.com/thread.jspa?threadID=286026&messageID=3034420)
which shows me ALL accessible resources (output in the
/var/log/php-java-bridge.log). ShowResources is called in UserClass2 before
trying to load Data.File.
With this information I saw, that only the classes of JavaBridge.jar and the
java-classes are accessible by the ClassLoader, but my jarfile.jar is not. 

So I tried to reference it in the php.ini with the setup-variable
java.classpath (I also tried java.class.path) but without any access. I also
saved the jarfile.jar under /usr/lib/php/extensions. Nothing is working;
everytime only the above mentioned classes are available.

So I'm at my wits end and I hope you can help me to solve this problem.

Many thanks in advance

Michael

Hi,

it depends how you search for the resources.  Currently only
findResource() is available. 

Since the JavaBridgeClassLoader is currently not(!) an URLClassLoader,
the ShowResources.listResources() function ignores it.  I will probably
change that for the next version 2.0.5.


As a workaround please copy your jar file(s) to $JAVA_HOME/jre/lib/ext,
for example to

   /opt/jdk1.5/jre/lib/ext

and re-start the bridge.

After that your jar(s) are loaded via the standard class loader.
