• 封裝所有的標準的COM接口，比如IUnknown, IDispatch等

• 支持標準的COM類型，比如Variant, SafeArray（一維或多維數組）、BStr等

• 支持VTBL方法調用機制，您可以使用函數標識來調用COM對象方法

• 通過自動支持，您可以完成：

• 使用動態方法調用技術，您可調用任意的COM對象的方法

• 獲取某個COM對象的任意屬性，包括標識號和名稱

• 設置COM對象屬性

• 支持COM事件。您可以采用標準的COM技術(findConnectionPoint/advise)，創建一個Java COM事件來管理和連接一個COM對象

• 在Swing程序中嵌入任意的OLE/OCX/ActiveX控件。ComfyJ提供了一個指定的OleContainer類，通過它，您可以完成：

• 使用ProgID, CLSID或者從文件，來嵌入一個對象，同樣您也可以將IOleObject插入到容器中

• 內置有多種OLE/OCX/ActiveX組件，包括Internet Explorer, Microsoft Office, Acrobat Reader 文件和多種媒體控件，比如Windows MediaPlayer, DVD player, QuickTime, ShockwaveFlash等 

• 為運行狀態提供了一個內置的顯示組件

• 通過指定二進制格式，來保存一個內置OleObject到文件中，或從文件中加載

• 支持多種不同類型的顯示操作，比如SHOW, INPLACEACTIVE等

• 支持DCOM，ComfyJ允許您在遠程服務器上創建COM對象

• 代碼生成程序。使用該程序，您可以將您的COM對象創建為Java COM封裝包。必要時，生成的類可以編譯及打包為單獨的JAR文件

• IUnknownServer —為IUnknown COM接口的提供運行服務

• 您所有執行IUnknown COM接口的Java COM對象都是基于這個類運行的

• IDispatchServer —為IDispatch COM接口的提供運行服務

• 您所有執行IDispatch COM IUnknown COM接口的Java COM對象都是基于這個類運行的

• 支持在運行時間創建和注冊您的Java COM類

• 該方法廣泛應用于OleContainer接口的執行和COM事件的支持中

•  支持創建任意的用戶COM類，并通過特點的專門設計的“服務管理”程序在系統中將其注冊為COM服務。

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.
