非maven版jeecg 项目搭建问题

夜雨颖雪

新手上路，下个3.75非maven版jeecg，用myeclipse导入，工具也是按提示加的 Tomcat7和jdk1.7但是弄好之后还是一直报这两个错 1： The project was not built since its build path is incomplete. Cannot find the class file for javax.servlet.http.HttpServletRequest. Fix the build path then try building this project 2：The type javax.servlet.http.HttpServletRequest cannot be resolved. It is indirectly referenced from required .class files 这是什么原因？？
