Struts2与Weblogic服务器配置注意事项

最近新项目打算用struts2与weblogic服务器搭建项目环境，本以为会很容易成功，没想到却花了我好多时间。

进入正题：

环境：weblogic9.2 MP3  、JDK1.7.3、Myeclipse8.5

一开始按照基本的struts2搭配环节进行，发现在服务器启动的时候，报错,大致如下：

在网上查了好多资料，都以为是jar包冲突，或者是jar没有导入导致的，其实还有另外的一种原因。

weblogic9.2启动部署的时候，默认的自带的jdk1.5，而这个时候我们的MyEclipse8.5用的是自己安装的jdk1.7.3，导致版本不一致

解决方法如下：右键需要部署的项目，选择—》properties—》java Compiler

将项目的编译器改成jdk.1.5的版本就OK了，再次部署，就不会出现找不到action的错误了
