1.先下载office2007 能另存为pdf的插件 SaveAsPDFandXPS.exe 安装

2.附件提供了jacob1.9的下载

3.这点很重要也是耗时我最久的就是jacob.dll与jacob.jar的存放位置;位置不对则会出现app.getProperty("Documents").toDispatch()这句话无法正常执行;

位置如下文件存放在jdk的 jre下 例如我这边是
jacob.jar 放在 E:\jdk1.5.0_14\jre\lib\ext
jacob.dll 放在 E:\jdk1.5.0_14\jre\bin
下能正常执行;
按网上说的 放在windows\system32下则会出现错误

源代码如下： 

package com;import java.io.File;import com.jacob.activeX.ActiveXComponent;

}
