eclipse新建JSP页面报错:Multiple annotations found at this line解决方法

错误提示：

Multiple annotations found at this line:
	- The superclass "javax.servlet.http.HttpServlet" was not found on the Java 
	 Build Path
	- The superclass "javax.servlet.http.HttpServlet" was not found on the Java 
	 Build Path

 

错误原因：缺少编译JSP页面的库：server Runtime ，一般出现在新安装的eclipse中。

解决方法： 

右键该项目---->点击build path---->选择configure build path---->下一步---->configure build path界面下找到java build path项---->Libraries选项下的Add Library---->找到server Runtime 然后next---->ok
