注册页面能打开，但是表单连不到servlet

这是jsp页面代码<%@page language = "java" import ="java.util.*" pageEncoding = "gbk"%>
<!DOCTYPE HTML PUBLIC"-//WOC//DTD HTML 4.01 Transitinal//EN">

</html>这是servlet代码
package com.servlet;import java.io.IOException;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;public class regservlet extends HttpServlet {

out.flush();
out.close();
}
 public void init()throws ServletException{

}
}
这是web.xml代码<?xml version="1.0" encoding ="UTF-8"?>
<web-app version="2.4"
xmlns= "http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee

</servlet><servlet-mapping>
<servlet-name>regservlet</servlet-name>
<url-pattern>/myregservlet</url-pattern>
</servlet-mapping>
</web-app>
这是tomcat里servlet.xml里添加的
 <Context path="/ServletApp" docBase="F:\Myeclipse\Workspace\ServletApp\WebRoot"
eloadable="true"></Context>就是不知道哪里出错了
