package javax.servlet do es not exist 怎么回事？(100分)

用JCreator2.5编译一个Servlet出错如下，用jb8可编译。我想可能是jCreator配置有问题，如何解决呀？

把j2ee包放到你的classpath里就行了
jb里有，用winrar打开可以看到javax包里的servlet类。。。

设置一下你的ClassPath就可以了，在Classpath中加上你的servlet.jar文件所在的目录名和
这个文件的名称以及扩展名

%tomcat_home%/common/lib下有个servlet.jar
加入到jcreator的classpath中去

多人接受答案了。
