I have a test case for this, which was unfortunately succeeding because it was configured on a per-webapp, rather than global basis, and was thus seeing the correct classloader. Global setting of the JGStore via the jboss-service.xml will now have it's classloader correctly initialised on webapp deployment.
Please let me know if you have any further problems,

After this (not so bright) introduction, here goes the problem:
Environment: JBoss 3.0.6 "all", Linux, Sun j2sdk_1.4.1_01.
I've got a web app that needs to replicate some http session info. I had two exceptions when I tried to access the app: a) could not marshal outgoing update [sender node] b) could not demarshal incoming update [receiver node]
I've figured out that the problem of a) lied in a class [JwmaSession] that was being stored in my http session:
public class JwmaSession implements Serializable {
//instance attributes private boolean m_Authenticated; private boolean m_LanguageToggled=true;
//http session state related private List m_BeanNames; transient private HttpServletRequest m_Request; transient private HttpServletResponse m_Response; transient private HttpSession m_WebSession; private String[] m_ViewHistory;
//mail session state related private String m_PostOfficeHost = null; private boolean m_PostOfficeConnected = false;
//utility attributes private JwmaPreferencesImpl m_Preferences; private JwmaHtmlHelper m_HtmlHelper=new JwmaHtmlHelperImpl();
private MailSession remote;
(...) private void storeDefaultBeans() {
//the session bean m_WebSession.setAttribute("jwma.session",this);
//the HtmlHelper bean m_WebSession.setAttribute("jwma.htmlhelper",m_HtmlHelper);
}//storeDefaultBeans
(...)
I got rid of "a)" by setting HttpServletRequest,HttpServletResponse and HttpSession as transients, as you can see in the code above. I've done this as the exception stacktrace was like this:
ERROR [org.mortbay.j2ee.session.JGStore] could not marshal outgoing update java.io.NotSerializableException: org.mortbay.j2ee.session.StateAdaptor at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1054) (...) at inocrea.web.webmail.model.JwmaSession.storeDefaultBeans(Unknown Source) (...)
This way, the node to where I directed the messege no longer reported those messages.
However, at the brother nodes, I still have the exception I posted at the top of this e-mail... and this is a bit weird for me:
ClassNotFoundException: inocrea.web.webmail.model.JwmaSession?!?
It makes no sense ... does it? The app is deployed in every node I've got! Can someone point me for a possible problem?
Thank you Joao Clemente
