I'm back from Christmas but still with my issue. BTW, my client is running on JBoss EAP 5.0.1 on RedHat in production. That's why I would like him to use JBoss in development. I'm managed to get a quick startup with a tweaked web profile but this WTP issue is really puzzling me.
If no one has an idea, can you help me to debug? What should I do to give you more information?
