problem with bean in IPortalComponentSession

Hi all,

we have a ep5-app that uses any beans stored in session . In intranet and on any internet-clients it works fine. But any Clients in internet can't use the app, because null pointer exceptions on getting a bean from session , which is created in doInitialisation, so that bean should exist. We've check allready all browser- and security-settings and have now the same on all test clients.

here's the exception:

com.sapportals.portal.prt.component.PortalComponentException: Exception during PageProcessorComponent.doContent()<br>at com.sapportals.portal.htmlb.page.PageProcessorComponent.doContent(PageProcessorComponent.java:143)<br>at com.sapportals.portal.prt.component.AbstractPortalComponent.service(AbstractPortalComponent.java:127)<br>at com.sapportals.portal.prt.core.PortalRequestManager.callPortalComponent(PortalRequestManager.java:291)<br>at com.sapportals.portal.prt.core.PortalRequestManager.dispatchRequest(PortalRequestManager.java:198)<br>at com.sapportals.portal.prt.component.PortalComponentResponse.include(PortalComponentResponse.java:231)<br>at com.sapportals.portal.prt.pom.PortalNode.service(PortalNode.java:475)<br>at com.sapportals.portal.prt.core.PortalRequestManager.callPortalComponent(PortalRequestManager.java:291)<br>at com.sapportals.portal.prt.core.PortalRequestManager.dispatchRequest(PortalRequestManager.java:198)<br>at com.sapportals.portal.prt.core.PortalRequestManager.runRequestCycle(PortalRequestManager.java:483)<br>at com.sapportals.portal.prt.portalconnection.sapnative.DelegatedPlugIn.handleRequest(DelegatedPlugIn.java:730)<br>at com.sapportals.portal.prt.portalconnection.sapnative.PortalPlugIn.handleRequest(PortalPlugIn.java:132)<br>at com.sapportals.portal.prt.dispatcher.Dispatcher.service(Dispatcher.java:635)<br>at javax.servlet.http.HttpServlet.service(HttpServlet.java:853)<br>at com.inqmy.services.servlets_jsp.server.InvokerServlet.service(InvokerServlet.java:126)<br>at javax.servlet.http.HttpServlet.service(HttpServlet.java:853)<br>at com.inqmy.services.servlets_jsp.server.RunServlet.runSerlvet(RunServlet.java:147)<br>at com.inqmy.services.servlets_jsp.server.ServletsAndJspImpl.startServlet(ServletsAndJspImpl.java:792)<br>at com.inqmy.services.httpserver.server.RequestAnalizer.checkFilename(RequestAnalizer.java:665)<br>at com.inqmy.services.httpserver.server.RequestAnalizer.handle(RequestAnalizer.java:312)<br>at com.inqmy.services.httpserver.server.Response.handle(Response.java:170)<br>at com.inqmy.services.httpserver.server.HttpServerFrame.request(HttpServerFrame.java:1170)<br>at com.inqmy.core.service.context.container.session.ApplicationSessionMessageListener.process(ApplicationSessionMessageListener.java:36)<br>at com.inqmy.core.cluster.impl3.ParserRunner.run(ParserRunner.java:30)<br>at com.inqmy.core.thread.impl0.ActionObject.run(ActionObject.java:46)<br>at java.security.AccessController.doPrivileged(Native Method)<br>at com.inqmy.core.thread.impl0.SingleThread.run(SingleThread.java:155)<br><b>Caused by: java.lang.reflect.InvocationTargetException:

    Is see that the exception comes from the de.octavia.portal.common.utilities.navigation.Navigation class in method generateXMLNavigation(Navigation.java:42

    which is again called by de.octavia.portal.common.controller.Controller$ControllerDynPage.onNavClick(Controller.java:199)

    could you send the code of these two methods ?

    Otherwise, this error seems strange as the object in IPortalComponentSession should not be deleted when more memory is needed. You could try HttpSession and see if there are any differences
