在使用IntelliJ IDEA、Maven和Tomcat的环境中，由于删除Tomcat服务器后未重新编译部署，导致项目无法正常运行。更换JRE到JDK6后，虽然找到了页面，但后台出现org.eclipse.jdt.internal.compiler.classfmt.ClassFormatException错误。同事的环境却未报此错。

1. 由于用的Intellij IDEA + maven + tomcat，由于昨天把tomcat server删除了一个，没有用maven编译部署一下，导致今天tomcat一直启动了但是找不到项目，跟着同事改了下面的红色配置，结果找到页面了，但是后台报上述错误，同事那边却不报错。
