servlet 问题
先说一下自己的配置啊！！！
C:\Program   Files\Apache   Software   Foundation\Tomcat   6.0\conf\Catalina\localhost   目录下配置webApp.xml       内容为 <Context   path= "/webApp "   docBase= "F:\webApp "   reloadable= "true ">
</Context>
在F:\webApp目录下建有src   ,WEB-INF目录   WEB-INF目录下有classes目录和web.xml文件web.xml内容为
<?xml   version= "1.0 "   encoding= "gb2312 "?>
