java读取word显示在jsp页面上

在最近的一个项目中需要将一段字符类型的文本存为word，html并要将word的内容保存在数据库中，于是就有了如下的一个工具类，希望能对碰到这样需求的朋友提供点帮助。
       匆匆忙忙的就copy上来了，没有做一些删减，有一些多余的东西，有兴趣的朋友可以自行略去。我的注释相对比较清楚，可以按照自己的需求进行组合。
      在操作word的地方使用了jacob(jacob_1.9)，这个工具网上很容易找到，将jacob.dll放置系统Path中，直接放在system32下也可以，jacob.jar放置在classPath中。


代码如下：WordBridge.java
