Serializable class throwing class cast exception.

All,

I have a serializable class name 'Owner' and while login to the application, i put the object of this class in the session. Later in my application, when i am trying to retrieve this obejct from the session using the following code, throwing class cast exception.

Owner owner =(Owner)request.getSession().getAttribute(WebKeys.LOGGEDINOWNER_OWNER_KEY)

This piece of code works fine in test enviornment(single server), but fails in production which is clustered enviornment.

Any help will be appreciated

You either have problems with different classloaders, or that you should use javax.rmi.PortableObject.narrow instead of just a simple cast.Kaj

Change it into:

Object owner = request.getSession().getAttribute(WebKeys.LOGGEDINOWNER_OWNER_KEY);

System.out.println(owner.getClass() + " : " + Owner.class);

And see what it prints..
