Hello fellow developers, I have also bumped onto the same problem when developing an application. Although I am using JSF and JBoss Application Server. The details of the exception I am getting is: type Exception report message description The server encountered an internal error () that prevented it from fulfilling this request. exception javax.servlet.ServletException: Error calling action method of component with id registerForm:registerUser javax.faces.webapp.FacesServlet.service(FacesServlet.java:152) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) root cause javax.faces.FacesException: Error calling action method of component with id registerForm:registerUser org.apache.myfaces.application.ActionListenerImpl.processAction(ActionListenerImpl.java:74) javax.faces.component.UICommand.broadcast(UICommand.java:106) javax.faces.component.UIViewRoot._broadcastForPhase(UIViewRoot.java:94) javax.faces.component.UIViewRoot.processApplication(UIViewRoot.java:168) org.apache.myfaces.lifecycle.LifecycleImpl.invokeApplication(LifecycleImpl.java:343) org.apache.myfaces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:86) javax.faces.webapp.FacesServlet.service(FacesServlet.java:137) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) note The full stack trace of the root cause is available in the Apache Tomcat/5.5.20 logs. I suspect this might be the wrong post, but snce I thought they are similar problems and someone seems to have solved it, I felt it appropriate to post it here. Apologies for any of mixups that may arise. I lok forward to your advice and reply.
