java.lang.NoClassDefFoundError: javax/media/opengl/GLCapabilitiesChooser

Hello everyone.

I just downloaded SweetHome 3d v3.4 src and followed the instructions given in the readme file to install it on a OS x 10.7.2.

The project was succesfully imported into eclipse and the VM argument -Djava.ext.dirs=lib:lib/macosx was included to run the project as a Java Application (SweetHome3d.java) and a Java Applet (SweetHome3dViewer.java)

The Java Application runs just fine, but when i start the Applet it gives me the following stack trace:

I went to the directory lib/macosx and the following files could be found:

gluegen-rt.jar
jogl.jar
libgluegen-rt.jnilib
libjogl_awt.jnilib
libjogl_cg.jnilib
libjogl.jnilib

I would like to know if I'm missing something here.

Re: java.lang.NoClassDefFoundError: javax/media/opengl/GLCapabilitiesChooser

Since it's more realistic, I generally run the applet from a browser after running Ant applet target.
If you run it with appletviewer from Eclipse and didn't change the working directory set to classes folder by default, set VM arguments to

-Djava.ext.dirs=../lib:../lib/macosx

Re: java.lang.NoClassDefFoundError: javax/media/opengl/GLCapabilitiesChooser

Thank you very much for your help.

I applied the change you mentioned, but it gave me an error opening the default sh3d file.

However, i used the Ant file and managed to run the applet in a browser like you said.

Thanks again.
