I also tried creating new EAR seam web project with JBDS 2.0.0.GA and seam 2.1.1.GA running on jboss-eap (installed as part of JBDS). Fails with same symptoms as above posts. Also fails if create new EAR seam web project using seam 2.0.2-FP (in same manner) So seems to be same failure across 1. Eclipse 3.4.2 + JBT 3.0.0 and JBDS 2.0.0 (so not installation issue with my JBT plugins) 2. JBoss AS 4.2.3 and JBoss EAP 3. Seam 2.1.1.GA and Seam 2.0.2-FP View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4224955#...
