Hi everyone,

I'm trying to use JBoss Tools to do a Seam web project.  It wasn't easy to install, but I did get it set up.

Now I am deploying a very simple test project, and I'm getting (trimmed for readability):

18:06:22,819 ERROR [AbstractKernelController] Error installing to Real: name=vfs:///usr/java/jboss-6.0.0.20101110-CR1/server/default/deploy/Testing-ear.ear state=PreReal mode=Manual requiredState=Real: org.jboss.deployers.spi.DeploymentException: Error deploying Testing-ejb.jar: Null class name

Any ideas on this?  I would love to start using this system but it seems very challenging to get it going.

Thanks
