javax.servlet包

javax.servlet包,是一款程序员编译的时候需要的包，有需要的下载哦

运行Servlet程序编译的时候找不到javax.servlet包

   解决办法：

   1：servlet-api.jar复制到 C:\%Java_Home%\jre1.5.0_10\lib\ext

   2：在classpath中加入“D:\Tomcat 5.5\common\lib\servlet-api.jar;”

以上方法你通过Javac 编译和运行就没问题 但是如果你是在Eclipse 环境下 编译起来还是

出现软件包不存在的问题；

   3：在Eclicpse8.6中还要配置引入这个包。方法是：

 打开project->project properties->Libraries->add external jars->把Tomcat下的

servlet.api.jar导入。

   4．完成。再次运行的时候就能通过了。
