I've been trying to get Portal to work on JBoss 4.0.4GA with Mysql 5.0.19, and have navigated my way through a variety of errors. Unfortunately, I can't get past the following. Any help would be greatly appreciated. exception javax.servlet.ServletException: Cannot invoke with a null interceptor[] org.jboss.portal.server.servlet.PortalServlet.process(PortalServlet.java:306) org.jboss.portal.server.servlet.PortalServlet.doGet(PortalServlet.java:172) javax.servlet.http.HttpServlet.service(HttpServlet.java:697) javax.servlet.http.HttpServlet.service(HttpServlet.java:810) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) root cause org.jboss.portal.common.invocation.InvocationException: Cannot invoke with a null interceptor[] org.jboss.portal.common.invocation.Invocation.invoke(Invocation.java:157) org.jboss.portal.server.servlet.PortalServlet.process(PortalServlet.java:294) org.jboss.portal.server.servlet.PortalServlet.doGet(PortalServlet.java:172) javax.servlet.http.HttpServlet.service(HttpServlet.java:697) javax.servlet.http.HttpServlet.service(HttpServlet.java:810) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3963337#...
