[Opensource] problem with Expresso503 in Iplanet

[Lirian Ostrovica]

Hi,

I have installed Expresso503 in Iplanet web server. (simply deployed expresso5-0-3-bin.war, with no changes on any config file)
When I try to login, I get :

ERROR [Thread-11] controller.Controller (Controller.java:1180) - Error in substate
java.lang.NullPointerException
 at java.util.Hashtable.put(Hashtable.java:380)
 at com.iplanet.server.http.servlet.NSServletRequest.setAttribute(NSServletRequest.java:342)
 at com.jcorporate.expresso.core.controller.session.HTTPPersistentSession.setAttribute(HTTPPersistentSession.java:78)
 at com.jcorporate.expresso.core.controller.ControllerRequest.getErrorCollection(ControllerRequest.java:429)
 at com.jcorporate.expresso.services.controller.LoginController.runPromptLoginState(LoginController.java:945)
and so on


method getErrorCollection() of ControllerRequest looks like :

public ErrorCollection getErrorCollection()  throws ControllerException {
        ErrorCollection ec =  (ErrorCollection) getSession().getAttribute(Action.ERROR_KEY);
        if (ec == null) {
            ec = (ErrorCollection)getSession().getPersistentAttribute(Action.ERROR_KEY);
            getSession().removePersistentAttribute(Action.ERROR_KEY);
            getSession().setAttribute(Action.ERROR_KEY,ec);   // line 429
        }
}

It seams that in line 429 variable 'ec' comes as 'null' and this causes the NullPointerException.

Does anyone has any clue on why this might happen ???
really appreciate any help
