Calling Java from C++

Hi,

Does anybody knows How to call java methods in C++ application?
If we want to call java in C++ first we need to create an instance of JVM in C++.
There are lots of references available how to do that. But nothings works properly. It failsto create the instance of JVM in C++. If anybody has done it & having it worked Please HELP me in this.It would be a great help. I think my application fails to create JVM instance because of the problem in configuration (path setting JVM)..Please give your hands

Thanks in advance
