What is the best way to pass information from java to c++?

Question

I have a java application I need to pass some info to a C++ program. It has been suggested that I use some simple socket programming to do this. Is this the best way? If not

Answer 1

There's also the option of SOAP but that's probably overkill assuming you've simply got two processes on the same machine. Still I mention it for sake of completeness.
