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:

Code: Select all

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.

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

Code: Select all

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

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.
