why java.io.NotSerializableException ?
hi
i have an application that should start an rmi registery and then put/get objects into it using JNDI.
When i'm running it i'm getting the following exception:]
javax.naming.CommunicationException [Root exception is java.rmi.MarshalException: error marshalling arguments; nested exception is:
