Java到COM的桥接

该桥接方式允许您轻松得在Java程序中整合任意COM/OLE/OCX/ActiveX库，您只需要编写纯粹的Java语言便可，无需其他语言支持。

主要特点有：

• 封装所有的标准的COM接口，比如IUnknown, IDispatch等

• 支持标准的COM类型，比如Variant, SafeArray（一维或多维数组）、BStr等

• 支持VTBL方法调用机制，您可以使用函数标识来调用COM对象方法

• 通过自动支持，您可以完成：

• 使用动态方法调用技术，您可调用任意的COM对象的方法

• 获取某个COM对象的任意属性，包括标识号和名称

• 设置COM对象属性

• 支持COM事件。您可以采用标准的COM技术(findConnectionPoint/advise)，创建一个Java COM事件来管理和连接一个COM对象

• 在Swing程序中嵌入任意的OLE/OCX/ActiveX控件。ComfyJ提供了一个指定的OleContainer类，通过它，您可以完成：

• 使用ProgID, CLSID或者从文件，来嵌入一个对象，同样您也可以将IOleObject插入到容器中

• 内置有多种OLE/OCX/ActiveX组件，包括Internet Explorer, Microsoft Office, Acrobat Reader 文件和多种媒体控件，比如Windows MediaPlayer, DVD player, QuickTime, ShockwaveFlash等

• 为运行状态提供了一个内置的显示组件

• 通过指定二进制格式，来保存一个内置OleObject到文件中，或从文件中加载

• 支持多种不同类型的显示操作，比如SHOW, INPLACEACTIVE等

• 支持DCOM，ComfyJ允许您在远程服务器上创建COM对象

• 代码生成程序。使用该程序，您可以将您的COM对象创建为Java COM封装包。必要时，生成的类可以编译及打包为单独的JAR文件

COM到Java的桥接

该桥接方式允许您像COM对象一样，执行和操作Java COM对象，您只需要编写纯的Java语言便可，无需其他语言支持。

主要特点有：

• IUnknownServer —为IUnknown COM接口的提供运行服务

• 您所有执行IUnknown COM接口的Java COM对象都是基于这个类运行的

• IDispatchServer —为IDispatch COM接口的提供运行服务

• 您所有执行IDispatch COM IUnknown COM接口的Java COM对象都是基于这个类运行的

• 支持在运行时间创建和注册您的Java COM类

• 该方法广泛应用于OleContainer接口的执行和COM事件的支持中

• 支持创建任意的用户COM类，并通过特点的专门设计的“服务管理”程序在系统中将其注册为COM服务。

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.
