Distributed systems

Q: I m researching methods by which one JVM can interact with another JVM,

which is running on the same machine.

I know that there are various network models, which can be applied if a JVM needs

to talk to another one across a network, but in addition to these (which could I guess

be applied to JVMs on the same machine) I wondered if you knew of a system of

JVM communication that requires less system resources, where the JVMs are both

running on the same system.

Answer: CORBA, RMI, HTTP, sockets....

But if you have no TCP/IP stack on your platform, so for Windows it could be

clipboard...

Q: I have a question about sending a reference to the object via the socket...

I have a question about sending a reference to the object via the socket. Two threads

are communicating via sockets running on the same machine. I don t need to send

the whole object, but I need to send just

a reference.

Does anyone knows how to do that?

Answer: Reference to an Object? A reference is only valid within the same memory

space! If you want to be able to invoke methods on an object remotely, then you will

need to use a remote technology like RMI, CORBA, or some such.
