Eclipse JSP调用Servlet的有关问题

Eclipse JSP调用Servlet的问题
比如Eclipse中的Dynamic Web Project工程A，A的webContent下的一个页面用表单调用servlet.

<form id="form1" method="post" action = "/JSPRequest/firstservlet">
  ......................................
<input type = "submit" value = "提交">
<input type = "reset" value = "重置">
</form>

A的WEB-INF中的web.xml已经配置：
<web-app>
  ...............................................
  <servlet>
  <servlet-name>firstservlet</servlet-name>
  <servlet-class>com.demo.servlet.FirstServlet</servlet-class>
  </servlet>
  <servlet-mapping>
  <servlet-name>firstservlet</servlet-name>
  <url-pattern>/JSPRequest/firstservlet</url-pattern>
  </servlet-mapping>
</web-app>

A的src中的com.demo.servlet中有FirstServlet.java
package com.demo.servlet;
.......................
public class FirstServlet extends HttpServlet{
public void services(HttpServletRequest request, 
HttpServletResponse response) throws ServletException, java.io.IOException
{
PrintStream out = new PrintStream(response.getOutputStream());
  .....................
  }
}

接着Run On Server 选择 tomcat 6.0.32
结果显示：

HTTP Status 404 - /JSPRequest/firstservlet

--------------------------------------------------------------------------------

type Status report

message /JSPRequest/firstservlet

description The requested resource (/JSPRequest/firstservlet) is not available.

请问我哪儿配置错了么？还是有什么细节的地方？



------解决方案--------------------------------------------------------
你把<form id="form1" method="post" action = "/JSPRequest/firstservlet">前面的/去掉看看
：
<form id="form1" method="post" action = "JSPRequest/firstservlet">
 
 
------解决方案--------------------------------------------------------

XML code

<servlet>        <servlet-name>            LoginServlet        </servlet-name>        <servlet-class>            org.cai.servlet.LoginServlet        </servlet-class>    </servlet>    <servlet-mapping>        <servlet-name>LoginServlet</servlet-name>        <url-pattern>/LoginServlet</url-pattern>    </servlet-mapping>
