关于java使用jacob调用word，ppt，excel等的转化为html的问题

使用jacob时，把dll放到window/system32下就成，不需要注册

1、如果出现下面的错误

com.jacob.com.ComFailException: A COM exception has been encountered:

At Invoke of: Version

Description: An unknown COM error has occured.

表示dll的版本不对，换成最新版本即可。

2、如果出现下面的错误

no jacob in java.library.path

java.lang.UnsatisfiedLinkError: no jacob in java.library.path

表示把dll放到path下即可，设置path或是放到window/system32下
