使用Myeclipse新建web项目后,index.jsp文件中报错

报错信息如下:
Multiple annotations found at this line:
- String cannot be resolved to a type
- The method getContextPath() from the type HttpServletRequest refers to the missing type
String
这是项目没有配置java library 导致的。
解决办法:
1. 选择项目----右键build path----configure build path

2. 在Java Build Path----Libraries tab中,点击Add Library按钮

3. 选择JRE System Library,点击Next
4. 由于安装完Myeclipse之后就已经配置过jdk,直接点击Finish按钮

5. 可以看到JRE library添加成功,应用并关闭窗口,会看到报错信息消失。
