Hello everybody,

I am trying to use the EPF Composer sources.

So, I followed this tutorial :
http://www.eclipse.org/epf/composer_dev_guide/dev_env.php
and
http://www.eclipse.org/epf/composer_dev_guide/run_debug.php

This last tutorial seems to be outdated, so I modified some fields.

I tried many things but i have always the same error and here the Exception Stack Trace :

org.eclipse.core.runtime.CoreException: Plug-in org.eclipse.epf.rcp.ui was unable to load class org.eclipse.epf.rcp.ui.MainApplication.
