At the moment I have the main jboss-seam.jar in the root of my .ear along with some other jars that are needed for a java library im using. All the jars that are needed in the web layer are in WEB-INF/lib: jboss-seam-ui.jar, ajax4jsf.jar, jsf-facelets.jar el-*.jar, jstl-1.1.0.jar, jboss-seam.debug.jar jbpm-3.1.4.jar I have also listed the following jars in my application.xml jboss-seam.jar el-api.jar el-ri.jar jbpm-3.1.4.jar I think the setup ive got eliminates the need for any jars to already exist in my jboss install, and i have only included the jars I need. Is this right? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4036163#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
