Struts2.1.8.1 + Pluto1.1.7 + portletV1.0(JSR 168) CRUD Demo(20091203止)

本來想用portlet2.0（JSR 268）整合Struts2的，但是Struts2的最新版的Portlet插件JAR包也僅僅支持JSR 168規範，所以只能退回去用戶JSR168了。。。

由於Pluto1.X系列和Pluto2.X系列配置PortletV1.0和V2.0的配置文件不同，這裡不闡述1系列的配置步驟，只提供已經由手工配置好的apache-tomcat-6.0.20版本+Pluto1.1.7版本+PortletV1.0版本的TOMCAT應用服務器（注意附件要將三部份全部下載完才可以應用）

如圖所示：展示Struts2與Portlet1.0 整合的數據CRUD操作（增刪改查）

其餘代碼在附件中的源代碼中

注意：DEMO中的相關jar包是通過tomcat中lib中引入的，將附件中的DEMO源碼下載下來后腰手工修改引入jar的位置，最好將附件中的tomcat-pluto-1三個部份zip下下來，重新制定tomcat的位置，然後修改工程中引入jar包的位置
