Hi all,
Anybody, please look at this problem. I am returning a object from my ejb remote method. Then i am getting the following exception.
I am not aware of this exception. Please help me. You can see the client and ejb code at the bottom.

java.rmi.MarshalException: CORBA MARSHAL 0x4942f89a No; nested exception is:

//Here is my client code that is calling remote method.

oSession = initICSSession();
final XRCTransferObject oResultTrObj=oSession.getObject();

public ICSSession initICSSession() throws Exception
{
// Create a ICS Session which will help generating reports
javax.naming.Context ctx = ICSAppManager.instance().
getInitialContext();
System.out.println("Context in initICSSession : "+ctx);
ICSSessionHome oSessionHome =
(ICSSessionHome) ctx.lookup("nodes/bpenumutNode01/servers/server1/ejb/com/att/erp/ejb/session/ICSSessionHome");
System.out.println("Lookup successfull : "+oSessionHome);
// CCLogger.log("Creating ICS Session");

ICSSession oSession = oSessionHome.create(m_oSuiteControl.getLoggedInUser());
System.out.println("Remote obj ICSSession created .. "+oSession);
return oSession;
}

Here is my stateful session bean method

//XRCTransferObject is stored in singleton bean(ObjectStore) by one more method which is called just before this method.
//XRCTransferObject is serialized object.

public XRCTransferObject getObject() throws Exception
{
System.out.println("In getObject method of XRCSessionBase.........");
System.out.println("In getObject() method os XRCSessionBase.... "+ObjectStore.getInstance().getXrcTrans());
ObjectStore objs = ObjectStore.getInstance();
System.out.println("ObjectStore : "+objs);
XRCTransferObject xrcObj = objs.getXrcTrans();
System.out.println("XRCTransferObject : "+xrcObj);
return xrcObj;
}

Hi,
I mentioned client piece of code in the post. please see it.It looks like this.

oSession = initICSSession();

// Here is the getObject method.
final XRCTransferObject oResultTrObj=oSession.getObject();

Hi, Where in your client code do you call the getObject method?

Hi, You need to upgrade to the latest fixes for RAD and WebSphere. There have been several fixes for CORBA issues.

Hi, The RAD tool has an updater application installed when you installed the tool.

If you wish to download them via the web, here is the WebSphere App Server link:
http://www-1.ibm.com/support/docview.wss?rs=180&uid=swg27006876

Download and install the refresh pack first, then the latest fixpak.

Here is the link for RAD:

Hi, no I am not sure your particular problem is fixed because I did not specifically look for your problem. I saw lots of CORBA fixes. However, if you call IBM to open a PMR they are going to tell you to upgrade.

I think you misunderstand the purpose of this n.g. - this is not an
official support channel - anyone who helps you here does so on their
own, not as part of their job. If you think you have a product issue,
open a PMR with IBM Support.

Hi,
I tested even with Fix Pack 6.0.1.1. The same exception is repeating. While googling with that exception i got that it is problem with java.

Please see the link below.
http://www-1.ibm.com/support/docview.wss?rs=1083&context=SSGMGV&q=&uid=swg1PQ81813&loc=en_US&cs=utf-8&lang=en+en

And i am very much new to websphere, I didn't understand what they mean exactly in that page. Can anybody please suggest what i have to do now.

Waiting for reply.

That does not match your problem. Did you upgrade WebSphere or only RAD?

Isn't there anyone more senior on your team who you can ask for help?
