there is no magic about the tooling projects.
Are you using War or Ear projects ?
hi max, it is an ear project
ok - then you need to at least use Seam 2.0.1 to get the test to run properly.
see http://jira.jboss.com/jira/browse/JBIDE-1129 and the related issues of the known issues with Seam 2.0.0 and Tools EAR testing.
I already was using 2.0.1.CR1. I just had thought Seam did not get initialized properly and so the Entity Manager. And I thought that was because i had something missing with the embedded JBoss. I discovered the thegenerated log4j configuration was at ERROR level so i did not see what actually happened down there. I changed it, traced it and solved the issue.
Thank you very much.
