Hi,

Apparently for your purposes you also need our ComfyJ product

http://www.teamdev.com/comfyj/index.jsf , but not only JNIWrapper.

Using ComfyJ (more precisely the CodegenForComfyJ utility that is available in ComfyJ distribution archive) you can easily generate Java wrappers for COM objects/interfaces/types that are defined in the required COM type library.

Then you can create a necessary COM object in your Java application. The code snippet below demonstrates how it works:

     // Initialize COM in the current Java thread

     ComFunctions.coInitialize();

     // Create COM object

     IUnknown object = new IUnknownImpl(CLSID_MyClassDatabase, ClsCtx.ALL);

     // Query the required interface from it

     MyClassDatabaseImpl myClassInstance = new MyClassDatabaseImpl();

     object.queryInterface(IID_ClassDatabase, myClassInstance);

     // or even simpler

     MyClassDatabaseImpl myClassInstance = new MyClassDatabaseImpl(object);

where CLSID_MyClassDatabase and IID_ClassDatabase are defined as following:

     private final CLSID CLSID_MyClassDatabase = new CLSID("{use real CLSID in the following format 00000000-0000-0000-0000-000000000000}"); 

     private final IID IID_ClassDatabase = new IID("{use real IID in the following format 00000000-0000-0000-0000-000000000000}");

But if your COM object supports automation, you can invoke its methods even without generated wrappers, using Automation technique. The following example demonstrates it:

     // Initialize COM in the current Java thread

     ComFunctions.coInitialize();

     // Create COM object

     IDispatch object = new IDispatchImpl(CLSID_MyClassDatabase, ClsCtx.ALL);

     Automation automation = new Automation(object, true); // true means that the current thread will be used for methods invocation

     automation.invoke("loadData");

     ...
