Java-to-COM Bridge
This bridge allows a Java application to easily integrate with any COM/OLE/OCX/ActiveX libraries using only the Java programming language and no native code.

The major features are:

• Wrappers for all standard COM interfaces, such as IUnknown, IDispatch etc.
• Support for standard COM types, such as Variant, SafeArray (single and multidimensional arrays), BStr etc.
• Support for VTBL method calling mechanism. You can invoke COM object methods using the function index.
• Automation support enabling you to:
  
  • Invoke any method of a COM object using dynamic method invocation technique.
  • Get any property of a COM object, including indexed and named ones.
  • Set COM object properties.
• Support for COM events. You can create a Java COM event handler and connect it to a COM object using a standard (findConnectionPoint/advise) COM technique.
• Embedding any OLE/OCX/ActiveX controls into a Swing application. ComfyJ provides a special OleContainer class allowing you to:
  
  • Create an embedded object using ProgID, CLSID, or from a file. Also, there is an ability to insert an IOleObject into the container.
  • Embed various OLE/OCX/ActiveX components, such as Internet Explorer, Microsoft Office, Acrobat Reader documents, and various media components such as Windows MediaPlayer, DVD player, QuickTime, ShockwaveFlash etc.
  • Perform static drawing of an embedded component.
  • Save/Load an embedded OleObject to/from a file in a special binary format;
  • Do various kinds of in-place activation, such as SHOW, INPLACEACTIVE etc.
• DCOM support. ComfyJ allows creating COM object on a remote server.
• Code Generation application. Using this application, you can generate Java COM wrappers for custom COM objects. Generated classes can be compiled and packed to a JAR file if necessary.

COM-to-Java Bridge
This bridge enables you to implement and expose Java COM objects as usual COM objects in the Java language without writing native code.

The major features are:

• IUnknownServer — Server implementation of the IUnknown COM interface.
• All custom Java COM objects that implement the IUnknown COM interface can be derived from this class.
• IDispatchServer — Server implementation of the IDispatch COM interface.
• All custom Java COM objects that implement the IDispatch COM interface can be derived from this class.
• Ability to create and register custom Java COM classes at run time.
• This technique is widely used in the implementation of the OleContainer interface and in COM events support.
• Ability to create any custom COM classes and register them as COM servers in the system registry using a specially designed "Server Manager" application.
