编译beans时，出现"包 javax.servlet 不存在"错误提示，请问怎样解决？？？

在编译beans时，出现"包 javax.servlet 不存在"，"包 javax.servlet.http不存在"的错误提示。请问这两个软件包是不是存在jdk里？为什么会出现这种问题？怎样解决？？？各位帮帮忙呀，我刚学jsp不久的，别再让问题打击我这弱小的心灵！

jdk中没有，如果你有tomcat有tomcat/lib/servlet中有，那你在classpath设置一下呀

赞同楼上的！
这里有很多相关的问题，你搜索一下！会找到很多。

你需要在CLASSPATH中指明javax.servlet包。
你用什么服务器？我的tomcat是3.2.1版本，我的servlet路径设的为：
E:\TOMCAT\lib\servlet.jar; 

servlet.jar包含的类有：

META-INF/
META-INF/MANIFEST.MF
javax/
javax/servlet/
javax/servlet/http/
javax/servlet/jsp/
javax/servlet/jsp/tagext/
javax/servlet/http/Cookie.class

把以下包加到CLASSPATH中就可以了!
c:\tomcat\lib\ant.jar;
c:\tomcat\lib\jasper.jar;
c:\tomcat\lib\jaxp.jar;
c:\tomcat\lib\parser.jar;
c:\tomcat\lib\servlet.jar;
c:\tomcat\lib\webserver.jar;
