how to make sure rmi object is exported

Is there any way I can make sure that an object has been exported when I called UnicastRemoteObject.exportObject(Stub,0)?

I'm having some cases when running the server apps with no exception, but sometimes the exported object is not found by the client, therefore producing this:

RemoteException
java.rmi.NoSuchObjectException: no such object in table

please help?

There are sevaral forums discussing the topic. The reason to that is that the object on the server has been garbage collected like stated in the forums. To avoid this you have to hold a reference to the object. Details you can find e.g. at sun's forum, Stackoverflow or here.

Did you put the RemoteObject in rmiregistry using Naming or Registry bind() or rebind() methods?... Using exportObject() means that the Object is eligible to be placed in Naming service...
