Java到COM的橋接

該橋接方式允許您輕松得在Java程序中整合任意COM/OLE/OCX/ActiveX庫，您只需要編寫純粹的Java語言便可，無需其他語言支持。

主要特點(diǎn)有：

• 封裝所有的標(biāo)準(zhǔn)的COM接口，比如IUnknown, IDispatch等

• 支持標(biāo)準(zhǔn)的COM類型，比如Variant, SafeArray（一維或多維數(shù)組）、BStr等

• 支持VTBL方法調(diào)用機(jī)制，您可以使用函數(shù)標(biāo)識(shí)來調(diào)用COM對(duì)象方法

• 通過自動(dòng)支持，您可以完成：

• 使用動(dòng)態(tài)方法調(diào)用技術(shù)，您可調(diào)用任意的COM對(duì)象的方法

• 獲取某個(gè)COM對(duì)象的任意屬性，包括標(biāo)識(shí)號(hào)和名稱

• 設(shè)置COM對(duì)象屬性

• 支持COM事件。您可以采用標(biāo)準(zhǔn)的COM技術(shù)(findConnectionPoint/advise)，創(chuàng)建一個(gè)Java COM事件來管理和連接一個(gè)COM對(duì)象

• 在Swing程序中嵌入任意的OLE/OCX/ActiveX控件。ComfyJ提供了一個(gè)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(gè)對(duì)象，同樣您也可以將IOleObject插入到容器中

• 內(nèi)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(yùn)行狀態(tài)提供了一個(gè)內(nèi)置的顯示組件

• 通過指定二進(jìn)制格式，來保存一個(gè)內(nèi)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(yuǎn)程服務(wù)器上創(chuàng)建COM對(duì)象

• 代碼生成程序。使用該程序，您可以將您的COM對(duì)象創(chuàng)建為Java COM封裝包。必要時(shí)，生成的類可以編譯及打包為單獨(dú)的JAR文件

COM到Java的橋接

該橋接方式允許您像COM對(duì)象一樣，執(zhí)行和操作Java COM對(duì)象，您只需要編寫純的Java語言便可，無需其他語言支持。

主要特點(diǎn)有：

• IUnknownServer —為IUnknown COM接口的提供運(yùn)行服務(wù)

• 您所有執(zhí)行IUnknown COM接口的Java COM對(duì)象都是基于這個(gè)類運(yùn)行的

• IDispatchServer —為IDispatch COM接口的提供運(yùn)行服務(wù)

• 您所有執(zhí)行IDispatch COM IUnknown COM接口的Java COM對(duì)象都是基于這個(gè)類運(yùn)行的

• 支持在運(yùn)行時(shí)間創(chuàng)建和注冊(cè)您的Java COM類

• 該方法廣泛應(yīng)用于OleContainer接口的執(zhí)行和COM事件的支持中

• 支持創(chuàng)建任意的用戶COM類，并通過特點(diǎn)的專門設(shè)計(jì)的“服務(wù)管理”程序在系統(tǒng)中將其注冊(cè)為COM服務(wù)。

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.
