错误：
The import javax.servlet.http.HttpServletRequest cannot be resolved
解决：
1、这是因为工程里面web-inf/lib目录下少了包：Package javax.servlet.http引起的；
（包的介绍可参见：http://java.sun.com/products/servlet/2.5/docs/servlet-2_5-mr2/index.html）
2、在tomcat（本人的当前版本6.0.18）lib目录servlet-api.jar，将其copy到工程里面web-inf/lib目录下；
或者Right Click Project Name -> Properties -> Java Build Path -> Add Library -> Server Runtime -> Apache Tomcat v7.0（里面包含相关的JAR档， 如servlet-api.jar、jsp-api.jar、tomcat-api.jar等）
