异常javax.servlet.jsp.JspException cannot be resolved

缺少两个依赖包，servlet-api，jsp-api，注意groupId是：org.apache.tomcat

在maven的pom文件中添加依赖包：

<dependency>
<groupId>org.apache.tomcat</groupId>
<artifactId>servlet-api</artifactId>
<version>6.0.24</version>
</dependency>

<dependency>
<groupId>org.apache.tomcat</groupId>
<artifactId>jsp-api</artifactId>
<version>6.0.39</version>
</dependency>

异常 javax.servlet.jsp.PageContext cannot be resolved

进入build path，引入tomcat的包即可。
