    Getting ClassNotFoundException: null class name

      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):

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

       

      Thanks
