java使用jacob将office文档转换为PDF格式

jacob 包下载地址： http://sourceforge.net/projects/jacob-project/

下载后，将jacob 与 jacob-1.19-x64.dll放到安装jdk目录中

jacob.jar  放入到 jdk/jre/lib/ext中

jacob-1.19-x64.dll放入到 jdk/jre/bin中

实现代码如下

package com.ypr.modules.op.utils;

import java.io.File;

import com.jacob.activeX.ActiveXComponent;
import com.jacob.com.ComFailException;
import com.jacob.com.ComThread;
import com.jacob.com.Dispatch;
import com.jacob.com.Variant;
