Jawin - a Java/Win32 interoperability project
The Java/Win32 integration project (Jawin) is a free, open source architecture for interoperation between Java and components exposed through Microsoft's Component Object Model (COM) or through Win32 Dynamic Link Libraries (DLLs). The current version of Jawin is 2.0-alpha1, build 2005-03-23. The most recent version of this document is located at the Jawin home, kindly hosted by SourceForge.net.
You can use Jawin to interact with scriptable applications such as the Microsoft Office suite. You can use Jawin to call scriptable logic components such as Microsoft's COM-based XML parsers and tools. You can also use Jawin to access Win32 API features such as the Windows registry, security APIs, and the event log. You can also use Jawin to make in-process interoperability with .NET code exposed as COM objects. In fact, Jawin allows your Java applications to call any legacy COM- and DLL-based code, without having to write any Java Native Interface (JNI) code. Using Jawin, you can call any component that can be scripted in the Windows environment. You can also call arbitrary COM components or DLL entry points.
