Java HotSpot Virtual Machine

i am developing a front end in java for an image processing Stuff.
The image processing algorithms are in c/c++. The Java is Used to display the images.
Actually The application has many modules like reading raw images from source, then processing them and generate the final out put. To have this there are different modules that process the images from raw to final stage. Each module uses the algorithm written in c/c++.
How can i use inter process communication within modules in java, so my modules knows the state of the other module. I need to store the state too that in case if application is stopped suddenly on renovation it shall start from the stage left.
