SunOne7 ejb deployment error

Hi, I'm trying to deploy an ejb on SunOne AppSvr7 (Solaris8).
However, I always get the following error:
Cannot deploy the component
error received from mbean null

This problem seems to be happening for every single jar that i tried to deploy.
Each jar files are uploaded (an can bee seen from the console), however, none of them are deployed.
Is there any configuration that might cause the problem?
If anyone out there could help, please, I'm sort of hitting the deadline.
The following message is found on the admin-server log:
