j-Interop: Open Source, Non Native access to DCOM

j-Interop(http://j-interop.sourceforge.net) implements DCOM wire protocol (MSRPC) to enable development of Pure Bi-Directional, Non-Native Java applications which can interoperate with any COM component.The implementation itself is purely in Java and does not use JNI to provide native access,thus being truly platform independent. It has full support for COM automation and supports callback from COM Servers (event handling).
