Cannot launch java swing application from within eclipse

Anyone?

The complete set of errors (that I don't get on windows) :

What components? When I installed Eclipse I installed the latest Version, the one from:


http://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/rel ease/ganymede/SR2/eclipse-java-ganymede-SR2-macosx-carbon.tar.gz

Help is still appreciated.

Could you please more specific instructions? The Eclipse version of the link above is the latest. Of course I had to re-install it.

The Java Preferences are the default and I don't remember myself having edited them before.

The problem regards the JV of Mac OS X. I installed the update by apple supposed to sort this out, but no use.

What are apple SWT Compatibility Libraries? I'm not finding them in the ADC downloads area.
