标签:get   直接   jdk   div   pos   开发   img   html   col   

一、开发工具:office 16、jacob-1.18-M2、jboss 1.6

二、开发配置:

       1、解压缩技术图片---》技术图片

       2、配置jacob:

                  A C:\Windows\System32 jacob-1.18-M2-x64.dll
                  B C:\Program Files\Java\jdk1.6.0_43\jre\bin jacob-1.18-M2-x64.dll
                  C D:\jboss-6.0.0.Final\server\default\lib jacob.jar

三、编写代码:
