All ways of JVM to JVM communication

Question

I want a list of all the ways two JVMs can communicate. The JVMs can be local or remote.

The obvious ones are

• Socket Communication
• RMI
• Shared Memory(File/Database)

Note: I am not interested in comparing these as the way we choose depends on the need. I am curious to know what all ways actually exist.

Answer 1

See inter-process communication.
