Could not start deployment

[freakou]

Hi all!

I'm working on JDeveloper 11g with jboss-4.2.2.GA and a database on Oracle11G.
My problem is that when I deploy my application, I have an error of deployment. What I really don't understand is that my application was working 3 hours ago.

You can see all the error there :

I don't know what does it mean but I know that there is some stuff about the ejb-jar.xml .

I hope you could help me.

Thank you
