j-Interop

If you are in search of a software library that can enable you to develop Pure, Bi-Directional, Non-Native Java applications which can interoperate with any COM component, then j-Interop is definitely worth a try. This library is an Open Source Java-based program that implements the DCOM wire protocol (MSRPC) to make it possible. One of the great features of this implementation is that it is purely in Java and does not require the use of Java Native Interface (JNI) to provide COM access. This means that you will be able to use j-Interop from any Non-Windows platform.

Within the package provided by j-Interop, pre-implemented packages for automation are included. These packages offer support for ITypeInfo, IDispatch, and ITypeLib. This makes the use of these features simple and efficient. However, in cases where automation is not supported, j-Interop also provides an API set to directly invoke operations on a COM server. This gives you the flexibility to use j-Interop in situations where automation alone is not enough.

Overall, j-Interop offers an amazing service for developers looking to create Java applications that can seamlessly interact with a COM component. Its purely Java-based implementation and support for a wide range of platforms makes it a fantastic choice for anyone who wants to develop interoperable applications without the constraints of their operating system.
