Hi Shane: Have you tried with just tomcat6 (jdk1.6) and GWT-1.4 (jdk1.4)? As explained in my posting, i use Seam-2.0.1-CR1, mapped SeamResourceServlet to /hub/resource/* and the endpoint URL in GWT widget to /hub/resource/gwt. I make sure that it works as stand-alone Seam Jpa example and GWT KitchenSink. The RPC integration did not work for me :-(. Is it worth to try the latest version from the source? Thanks BaTien, dbgroups View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4116566#...
