myeclipse运行Struts2问题

[ddxu]

控制台显示如下，改过jre（我电脑安装的jdk和jre都是1.8的，新建的是web project，选择的是javaEE5.0）

Servlet.service() for servlet [jsp] in context with path [/Struts2-2] threw exception [Unable to compile class for JSP 你这是在jsp里面写了后台代码？

引用 1 楼 shijing266 的回复:

我在jsp页面用的是form的action，问题出在这个地方：arg2.doFilter(req, resp); 我认为应该是环境问题，但是不知道怎么解决，网上说过的办法我都试过了。
