Seam 2.0.1.GA is the only one that actually works with JBoss Tools. 2.0.0.GA had other issues like the embedded test container not working well from within eclipse with WTP projects. "However I see that the deployer first created a directory jboss-seam-2.0.1.GA.jar and then puts jboss-seam-2.0.1.GA.jar in it! Very strange but the deployment works!" ?! Are you using our patch or not ? That should not happen in any case. Could you please report that in jira ? Thanks!
