Can you try it with JDK 1.5? Also, is it possible for you to try Seam 2.0 (or from the CVS)? We made quite a few changes to that part of the code in Seam 2.0. To run Seam 2.0 on Tomcat, you will need to install the JBoss Embedded on Tomcat first, please see the docs for more details. Thanks. cheers Michael View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4069935#...
