Java Point / Discussion / Developers: Run problems

prince - 2010-05-24

I tried to run the application in my Ubuntu virtual machine, got following:

arkadyz@arkadyz-laptop:~/JavaPoint/dist$ java -jar JavaPoint.jar

Does anybody have thoughts ?

Thank you in advance.

http://ubuntuforums.org/showthread.php?t=1099777 Look at this.
I ran it under Ubuntu in a windows 7 virtual machine and it ran fine. I also read that this may only occur on 64 bit java jres. Do you have a 32 or 64 bit processor?

Great !

I did exactly as they suggested (should install one package) and it succeeded. My machine is WinXP 32 bit, I created a VM and installed Ubuntu 10.04 there.
Thank you,
Arkady.

The "single jar" version of JavaPoint is not in dist/ but in store/.

To generate it, go to the "Files" view in NetBeans, right click on build.xml and choose "Run Target" > "Other Targets" > "package-for-store".

Your console output in Windows XP isn't normal, the line references shouldn't be in Utilities.
Can you do a diff to see if your Main matches r233?

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

prince - 2010-07-10

My main.java is up-to-date, r233. I updated jar in store/ but still can't run it from Windows.

What do you mean "single.jar" version ? Is it without lib/ directory ?

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

Kyle Flanigan - 2010-07-10

Yes, the single jar version is the jar in the store folder. It has it's library files stored inside of the jar to create a single file so users wont have to mess with other folders when moving the program.

Have you tried running other java jars? I'm not sure if this is something wrong with your computer or the program.

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

I understood why I can't run in windows.

We have following condition in Main.java:

            if (arguments.length == 0 && System.getProperty("os.name").toLowerCase().startsWith("win") &&
                    originalFile.getName().endsWith(".jar")) {
……………………………………

                    return;
           }

This is exact the case when I try to run in Windows.

This test is here on purpose; if the program starts normally, the jar stays locked and "save in jar" doesn't work.
The program is restarted at line 89 (Runtime.getRuntime().exec(command)).

This output is not normal:

javapoint.Utilities.debugPrint(Utilities.java:252) C:\DOCUME~1\arkadyz\LOCALS~1\ Temp\log2733483289589678041.txt

It should have been:

javapoint.Main.getLog(Main.java:37)

My post seems to have failed.

I'm trying to add the missing part.

This output is not normal:

javapoint.Utilities.debugPrint(Utilities.java:252) C:\DOCUME~1\arkadyz\LOCALS~1\ Temp\log2733483289589678041.txt

It should have been:

javapoint.Main.getLog(Main.java:37) C:\DOCUME~1\arkadyz\LOCALS~1\ Temp\log2733483289589678041.txt

What do you have in Main.java line 37?

log2733483289589678041.txt is the log file for the restarted application.

What is its content?

Does it work if you use the latest release instead of building it yourself?

I can't run the latest release from Windows too. Where is log2733483289589678041.txt ?

Where is log2733483289589678041.txt ?

It's in your Temp/ folder.
The path is displayed in the message (C:\DOCUME~1\arkadyz\LOCALS~1\ Temp\).

If you have tried several times, this folder should be full of temporary files.

I suggest you clean it and run JavaPoint again.

After that, you should have:
* a temporary jar (maybe);
* a temporary .dict file (maybe);
* 2 log files (sure).

One of these logs is for the first stage (before the restart), the other one is for the second stage (after the restart).

I'd like to see both.

I ran release version, see only 1 log file: log2609580182436507789.txt. Don't see option to attach file, its contents are:

Codist Monk - 2010-07-11

see only 1 log file

That means the application doesn't restart properly.

I suspect it is locked on the "print('.')" because it cannot use the standard output.

I will try to find a workaround.

Your output really puzzles me.

If you add the following line at the beginning of main():

System.out.println(java.util.Arrays.toString(Thread.currentThread().getStackTrace()));

What does it write?

java.lang.Thread.getStackTraceImpl(Native Method)

This is what disrupts the line references.

What version of Java are you running?

Can you run the application from the command line with:

start JavaPoint.jar

If it doesn't work, then we can try to replace "start" with "java -jar" in main().

I am running following version of java:

start JavaPoint.jar doesn't work.

Cf 3003446

Shortly: Windows locks the jar when it is running, making runtime modification (like "save in jar" feature) impossible.
It works fine on Mac and Linux.
The workaround on Windows is to restart the application from a temporary jar, thus unlocking the original jar.

If you know of a simpler way, I would be glad to use it.

This is java of IBM (not of Sun).

Good to know, I never used it before.

I will soon commit a fix for debug() and debugPrint().

start JavaPoint.jar doesn't work.

That's why the restart fails.

Can you try by replacing "cmd /c start " with "cmd /c java -jar " (line 84 in Main.java)?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

I replaced "start" by "java -jar" and it succeeded to start !!!!!!!

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

This is output after the replacement:

I updated Utilities, the line references should work now.

I replaced "start" by "java -jar" and it succeeded to start

That's fine, but now my concern is whether the first stage terminates correctly.

If it doesn't, the jar will stay locked.

Does the save button work?

Yes, save button works.
