Running Jar File in Mac

[Mitsaki]

Hello,

I have changed the code of Sweethome3d in order to create my own application and I have created an executable jar file. I would like to run it from command line, but for some strange reason it does not.

I use this command in terminal
java -jar Blender.jar -Djava.ext.dirs=lib:lib/macosx

but it gives me this mistake

Exception in thread "main" java.lang.SecurityException: sealing violation: package javax.media.j3d is sealed

at com.eteks.sweethome3d.Blender.main(Blender.java:181)

What I have also done is change the MANIFEST.MF in order to have my main class as the main class of the program. Is that wrong?

Manifest-Version: 1.0
Created-By: 1.5 (Sun Microsystems, Inc)
Main-Class: com.eteks.sweethome3d.Blender

Could you tell me if you have any idea what I am doing wrong?

[Mitsaki]

Well, even if I don't change the manifest, it still doesn't run.

Even with this: java -jar Blender.jar -vmargs Djava.ext.dirs=lib:lib/macosx

I use this command in terminal
java -jar Blender.jar -Djava.ext.dirs=lib:lib/macosx

In what folder did you run this command?
Did you try with absolute paths instead of relative paths "lib" and "lib/macox"?

Even with this: java -jar Blender.jar -vmargs Djava.ext.dirs=lib:lib/macosx

-vmargs isn't a java command option!

Your problem is due to the fact that the JVM doesn't find the Java 3D libs in the extension folders you specified, so it uses the default old ones in the system found in /System/Library/Java/Extensions/. The easiest way to check this is to temporarily remove the j3d*.jar files from this folder, then when you run again your java command, you'll get a NoClassDefFoundError exception about a Java 3D class.

I have placed my Blender.jar file in a folder in my desktop. First I open the folder using the cd command, and then I run the jar file. But it seems not to recognize the VM arguments.

You are right about -vmargs, but I was reading a forum and I got confused. I removed temporarily the jar files from this folder as you said, and I got the message.

Now, I tried to run the SweetHome3D-3.3.jar file and it runs perfectly from command line using the command as before.

I will try with absolute paths, and I will tell you the result.

[Puybaret]

I tried to run the SweetHome3D-3.3.jar file and it runs perfectly from command line using the command as before.

It even runs without the -Djava.ext.dirs option. [;)]
If you want to make your program work as SweetHome3D Jar executable, study how it is built with jarExecutable Ant target.

[Mitsaki]

Thanks for the advice.

[Mitsaki]

Well, I tried to do it with absolute paths, but no luck. I cannot understand.

[Mitsaki]

Well, I used the absolute paths in order to show in the Sweethome3d source code right? lib: /Users/dimitramicha/Documents/workspace/SweetHome3D-3.3-src/lib
and lib/macosx: /Users/dimitramicha/Documents/workspace/SweetHome3D-3.3-src/lib/macosx
which are in the workspace.
Which main should I keep? I kept as run configurations the ones that I use to execute the program right? I really am very confused.

[Mitsaki]

I also try to do it with the existing source code, in order to see if I have some mistakes in my code, but the jar file that I export, does not run.
