已经解决
原因：项目下面的lib目录包含servlet-api.jar以及jsp-api.jar，编译的时候回打包到tomcat的config的lib西面，因为tomcat已经有了这两个jar包，导致冲突
解决方法，移除相关没有用的jar包，将上面两个jar包创建一个library，选择system library 在输入新的user library名字的下面有勾选然后重新引入，这样就不会编译的时候复制这两个jar包了

- 终于把springside4跑起来了
- springside4发布包中不再包含所有依赖jar，只包含源码,maven和ant命令。 自己补这些包可够费劲的。 可以从springside3的showcase的lib拷贝一些过来。
