TopLink, ADF 11g, RemoteSession and Stack Over Flow

Question

Hi,
I am using TopLink and ADF 11g. From managed bean I can invoke Toplink Remote Session. After commit transaction on Remote Unit Of Work I get next exception:
11.8.2009 14:52:47 oracle.adfinternal.view.faces.config.rich.RegistrationConfigurator handleError

Where can be problem? When I use DatabaseSession, all work correctly.

Hi Chris,
thanks for your response. I was take next fragment of source code for Server session, Client session and Remote session.
On server side:
Acquire Server Session:
private synchronized void createServerSession(boolean setEventListener){
serverSession = null;
if (toplinkProjekt == null) return;
Server serverSess = toplinkProjekt.createServerSession();
if (setEventListener) {
SessionEventListener eventListener = new SessionEventListener("ToplinkProjectManager.createServerSession", true, ESessionType.ServerSession);
serverSess.getEventManager().addListener(eventListener);
serverSess.setLogLevel(DefaultSessionLog.ALL);
serverSess.login();
serverSession = serverSess;
Acquire client session:
public RMIRemoteSessionController getRemoteSessionController(String firma) {
RMIRemoteSessionController rmirsController = null;
try {
ClientSession clientSession = getClientSession(firma);
if (clientSession != null) {
try {
rmirsController = new RMIRemoteSessionControllerDispatcher(clientSession);
} catch (RemoteException e) {
e.printStackTrace();
} else {
System.out.println("\n" + userIdentifikator + "\nzamietnuty pristup.\n\n");
} catch (Exception e){
e.printStackTrace();
System.out.println("\n\n\n" + userIdentifikator + " dostal RMI controller: " + rmirsController+ "\n\n\n\n\n");
return rmirsController;
private ClientSession getClientSession(String firma) {
if (AccessControl.canAccess(firma, userIdentifikator)) {
return DBConnectionManager.getClientSession(firma, userIdentifikator);
} else {
return null;
Methods getClientSession and getRemoteSessionController are in Statefull EJB T3ConnectionManagerSessionEJBBean and getRemoteSessionController is published accross the Remote interface.
Remote site:
private static Context getInitialContext() throws NamingException {
Hashtable env = new Hashtable();
env.put( Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory" );
env.put(Context.PROVIDER_URL, "t3://192.168.1.107:7101");
return new InitialContext( env );
private static RemoteSession createRemoteSession(String firma){
T3ConnectionManagerEJBBeanRemote t3Connection = null;
try {
final Context context = getInitialContext();
t3Connection = (T3ConnectionManagerEJBBeanRemote)context.lookup("T3ConnectionManagerSessionEJBBean#sk.egroup.toplink.sessions.t3connection.T3ConnectionManagerEJBBeanRemote");
} catch (Exception e) {
System.out.println("Lookup error - " + e.toString());
return null;
if (t3Connection == null) return null;
RMIRemoteSessionController controller = null;
try {
controller = t3Connection.getRemoteSessionController(firma);
} catch (Exception e) {
e.printStackTrace();
return null;
if (controller != null) {
RMIConnection rmiConnection = new RMIConnection(controller);
RemoteSession session = (RemoteSession)rmiConnection.createRemoteSession();
SessionEventListener eventListener = new SessionEventListener("FIRMA = " + firma, true, ESessionType.RemoteSession);
session.getEventManager().addListener(eventListener);
session.setLogLevel(DefaultSessionLog.ALL);
return (RemoteSession) session;
} else {
System.out.println("Nepodarilo sa ziskat remote session.");
return null;
Best Regards,
Jozef
