I have a method in a D program which I want to call from a Java program. What is the best way to do this?

Usually, to have two languages talk to each other, you have to have a C layer in between. So, AFAIK, that's what you have to do, but there may be a better way to handle it in this case that I don't know about.

What you need is Java JNI: http://en.wikipedia.org/wiki/ Java_Native_Interface . There are many examples how to do this in C or C+ +. It should not be any different in D.

I meant that the programs are running. So there is a runnung program in D and a running program in Java. What is the best way to communicate between them?

Pipes or sockets

Have them communicate via sockets just like you'd talk to a program on another machine (except that the IPs will be 127.0.0.1).
