I have Programm A (written in C++/Qt) and a Programm B (Java)[it starts Program A]. Everyone has the pid of the other. Now I need to implement a sharing of Informations and methods. But I don't know what the best solution can be. This will be a little animation program, so there is a lot of data that needs to be shared (timeline, 3D-Objects, Meshes, Graphs, ...)

My Ideas:

create with JNA a surrounding, and the Java program starts the program with a method in the library inside of a new process/thread.
or the same with JNI
or implement this with two pipes/streams (but I think, this will be complicated with many pieces of information, but if it is not, I'm open)
or with something with shared memory

The problem:

I have no idea what the best solution is and how I can implement that (I know how I can do that with pipes). Can anybody help me?
