moving JARs from NetBeans/PC to Mac

[dorito]

I have built an app in NetBeans on a PC and compiled it into a JAR file - Qubic.jar. I now want to move that to a Mac Pro and run it. What I actually ended up with was:

dist/
Qubic.jar
lib/
appframework-1.0.3.jar
swingworker-1.1.jar

When I recreate this directory structure on the Mac in Terminal and run the app (java -jar Qubic.jar) it does not run because it cannot find the class definition of SingleFrameApplication. On the web I see that this is because it is not using the right class path. So I tried:

export CLASSPATH=/Users/....

and also :

java -cp /Users/...

but neither of these helped. Then when I did a "man java" it says that when using a JAR file (-jar xxx.jar) all user classes must be in that JAR. When I extract all the JAR files in their respective locations, it still doesn't work.

Does anyone have any experience with this?

Thx,
Chris

Read this tutorial and pay special attention to the manifest section. You can specify a classpath in the manifest file and store that in your .jar file.

Well .. the answer turned out to be that the version of Java I was running on the Mac did not include javax.swing.grouplayout ... so I had to locate and run version 1.06.xxx of the JRE. Then everything was OK.

Still, I learned a lot about JARs and the MANIFEST. Thanks,

@dorito
The JVM should've thrown an Exception because of that: it can't find the class GroupLayout ...
