Hi. I posted this at Configuration, Instalation and deployment section. But I'll post it here as well. I have built a HelloWorld EJB application consisting in a Servlet and a Session Bean. Ant worked propperly and everything seems to be correct. JBoss instalation is ok and startup works well too. But when deploying the .ear file, the following error appears: 00:47:26,462 ERROR [AbstractKernelController] Error installing to Parse:

Any idea on what could be happening to the app? is the .ear correctly built? What .xml could be causing the parsing error? Any idea would be helpful.
