Hi, We have been facing an exception for some time now where an exception is raised at the time of login if the application is left idle for a few hours. This especially happens if the JBoss AS 3.2.7 is left running over night. The next day, on login attempt the following exception is raised Caused by: javax.faces.FacesException: #{index.validateUser}: javax.faces.el.EvaluationException: java.lang.NullPointerException at com.sun.faces.application.ActionListenerImpl.processAction(ActionListenerImpl.java:78) at com.sun.rave.web.ui.appbase.faces.ActionListenerImpl.processAction(ActionListenerImpl.java:57) at javax.faces.component.UICommand.broadcast(UICommand.java:312) at javax.faces.component.UIViewRoot.broadcastEvents(UIViewRoot.java:266) at javax.faces.component.UIViewRoot.processApplication(UIViewRoot.java:380) at com.sun.faces.lifecycle.InvokeApplicationPhase.execute(InvokeApplicationPhase.java:75) at com.sun.faces.lifecycle.LifecycleImpl.phase(LifecycleImpl.java:200) at com.sun.faces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:90) at javax.faces.webapp.FacesServlet.service(FacesServlet.java:197) ... 37 more Caused by: javax.faces.el.EvaluationException: java.lang.NullPointerException at com.sun.faces.el.MethodBindingImpl.invoke(MethodBindingImpl.java:130) at com.sun.faces.application.ActionListenerImpl.processAction(ActionListenerImpl.java:72) ... 45 more Caused by: java.lang.NullPointerException at com.tabaq.edocument.login.jsf.LoginValidator.validateUserPassword(LoginValidator.java:110) at edocument.index.validateFields(index.java:480) at edocument.index.validateUser(index.java:437) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) We have not been able to narrow down the root cause of this problem. I am also not sure of the exact time period which causes problem. I will appreciate if someone can help me find a solution to this. Thanks in advance. regards, Sultan View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4173024#...
