注意事項如下

OPC和Dcom配置，一定要配置好Dcom；不然很懵逼，發現很好的配置教程如下

https://www.cnblogs.com/ioufev/p/9365919.html

如果Dcom設置有問題或者用戶名密碼有問題，都會報錯0x00000005

org.jinterop.dcom.common.JIException: Access is denied, please check whether the [domain-username-password] are correct. Also, if not already done please check the GETTING STARTED and FAQ sections in readme.htm. They provide information on how to correctly configure the Windows machine for DCOM access, so as to avoid such exceptions.  [0x00000005]

 

ProdId無法使用報錯0xC0000034，需要使用CisId

org.jinterop.dcom.common.JIException: Message not found for errorCode: 0xC0000034

 

如果Clsid設置錯誤，極可能報錯RuntimeException: java.lang.ArrayIndexOutOfBoundsException: 16

注意clsId不是組件服務裏面的服務id；注意不是下面這個應用程序ID，雖然長的很像很像！

 

 

而是註冊表裏面的clsid；如下圖所示；
