Question

What is the basic difference between java.rmi.server.UnicastRemoteObject and java.rmi.PortableRemoteObject.

I know that one is used for JRMP and the other for IIOP,but can anyone explain it in a lay man's language.I'm new to Java.Also can we use a Protable Remote Object for JRMP? If not,why?

Was it helpful?

When do I use UnicastRemoteObject vs PortableRemoteObject?

UnicastRemoteObject should be used as the superclass for the object implementation in RMI programming. PortableRemoteObject should be used in RMI-IIOP programming. If PortableRemoteObject is used, you can switch the transport protocol to either JRMP or IIOP during runtime.
