Jar not deploying under linux

[balteo]

Hello,
I am new to linux and I have installed Jboss and I am trying to deploy a ejb jar file in the deploy directory. It does get copied into the deploy directory by Netbeans but it is not picked up by the jboss deployer. I suspect this is a permission problem but I don't undestand because the jboss system files are of the same permission as the ejb jar file. I use Jboss 4.0.3
Can anyone help please?
Thanks,
Julien.

I always put my jar file inside an ear file and copy the ear file to the deploy directory.
