jacob转html( 转)

 

客户要求上传的doc和xls附件能直接打开预览，不要下载后才能打开的。想到将如果将doc转成HTML不就OK 了吗？网上还真找到了转换之法：jacob。
此例演示在jdk6下将word、excel和ppt文件转成html文件。
1.首先需要jacob包。可以从http://danadler.com/jacob/上取的。
2.解压得到两个文件jacob.jar（直接放到classpath下去就行了），还有一个jacob.dll放到 system32或者 jdk安装目录的jdk/jre/bin目录中就OK了。
3.传说如果是win2003还需要安装一个东西。http://www.microsoft.com/downloads/details.aspx?familyid=200B2FD9-AE1A-4A14-984D-389C36F85647&displaylang=en&displaylang=en
不过我的是xp，不需要。

4.貌似需要安装offices，因为jacob是调用微软offices去转化文件的。（不知道有什么替代的办法没有）
