MS Office2010、WPS2015、OpenOffice4用Java将Office文档转换为PDF，WIN7 64位系统

1.前言

MS Office2010是可以的，理论上2007版本也可以，博主没试过；

Wps2015是可以的，理论上Wps2016也能用，Wps理论上还兼容MS Office的相关代码，有时间的可以试试；

Wps和Ms Office都需要导入jacob-1.18.jar包，以及将jacob-1.18-x64.dll或者jacob-1.18-x64.dll放置到jdk的bin目录（或者windows的System32/SysWoW64目录下）

而OpenOffice需要导入jodconverter-2.2.1.jar等相关包；

相关包的下载链接，包含实现代码：http://download.csdn.net/detail/huitoukest/9506740

包中的代码可能没有捕获NoClassDefFoundError异常和，建议使用者自行捕获；

核心代码如下：

//private static final int msoTrue = -1;
//private static final int msofalse = 0;
