Hi all,

I have migrated our RCP application from eclipse Indigo to Juno (3.8 not
e4!).
Our application is deployed to clients using webstart technology.
After the migration a NPE is raised on launch. Here's the stacktrace:

!SESSION Tue Oct 02 14:47:12 CEST 2012
-----------------------------------------
!ENTRY org.eclipse.equinox.launcher 4 0 2012-10-02 14:47:12.375 !MESSAGE

What I'm missing?

Any help is appreciated, kindly elvisd

It appears that the WebStartMain is not able to find the framework. Looks much like https://bugs.eclipse.org/bugs/show_bug.cgi?id=213698

Hi Thomas,

thank you for your input.
That lead me to resolve my issue.

The resources jnlp was not correctly defined (syntax errors) and the
org.eclipse.osgi (and others) jar wasn't downloaded.

Many thanks
