Seam 2.0.CR2 ( 5 oct 2007) works quite fine. I obviously skipped one important point : there is no way running multiple seam apps on the same tomcat. See end of page at http://wiki.jboss.org/wiki/Wiki.jsp?page=EmbeddedAndTomcat When I remove the previous example, I can test a new seam example and everything is fine. I apologize for this too quick conclusion. Have great moments with seam, out there. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4095812#...
