How to interface java and C++ ?

I have a java/swing interface and C++ processing engine. How I execute C++ program from JAVA ? Right I have shell script in which java compiles C++ and writes the output to a file and JAVA reads it from there. Is there any better and elegant solution ?

JNI isn't strictly necessary here. There are other solutions that might work better for you. One is simply calling the executable from Java -

Another is using XML-RPC. I've taken this route in the past when building processing engines in C++ because the engines stays loaded in memory and doesn't have to reside on the same machine.

Much of the XML-RPC stuff has been replaced by web services, but XML-RPC is much simpler and is very light weight.
