    NPE JBossWebRealm.hasRole Line 537

    pcarrollnf

      I am using JBoss 5.1.0 GA with JDK 1.6_16. I have a menu bar at the top of each of my JSPs. It performs a check to determine the roles a user is a member. Based on this information, the user will see certain links on the menu bar. However, when navigating through the pages, the following is displayed in the log:

      2009-11-03 11:26:11,363 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/].[jsp]] Servlet.service() for servlet jsp threw exception

      Sometimes the page will not display but when I refresh the page it displays fine. The error still is logged even during the refresh. Also, the appropriate links are displayed in the menu bar.

      I also tried replacing the jboss-web-service.jar from the attachment at https://jira.jboss.org/jira/browse/JBAS-7179 but this caused the app server to fail on startup. Just wondering if someone else ran into the problem and found a solution. Thanks.

          I'm having the same problem and I have also tried the workaround using the attatched jar (https://jira.jboss.org/jira/browse/JBAS-7179) without success (the web server fails to start).

           

          I have also tried to create the simple valve (attatched in the same jira) and added conf to server.xml but the problem remain exactly the same.

           

          Using JBoss 5.1.0GA

           

          Any updates on this?

           

          There are a number of issues in JBoss 5.1.0GA and it looks like all effort is on JBoss 6 and no ambition at all to create SP for 5.1...am I correct? I'm trying to upgrade from 4.2 but are about to give up due to all different problems.
