One more question. Is there any advantage to converting a .jar library to a .so library and using it as opposed to simply using the original .jar file with the Java invocation API and the JNI to call back to C++ from Java? I thought I would get a performance increase with using the .so library but perhaps there are no substantive differences between the two approaches.
It depends on how much work the code in the .jar is doing. Compiling to a .so will generally produce faster code, but the memory overhead of a .so may make using the interpreter on the .jar a better option.
If you really care, you could try both ways. David Daney
