web.xml注册问题?

<servlet>
<servlet-name>Test</servlet-name>
<display-name>Test</display-name>
<description>A test Servlet</description>
<servlet-class>test.Test</servlet-class>
</servlet>
<servlet>
....</servlet>
....<servlet-mapping>
<servlet-name>Test</servlet-name>
<url-pattern>/Test</url-pattern>
</servlet-mapping> <servlet-mapping>
....
</servlet-mapping> 呵呵，servlet和mappin 多写几个就行了

在tomcat中用
<servlet>
<servlet-name>invoker</servlet-name>
<servlet-class>
  org.apache.catalina.servlets.InvokerServlet
</servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>0</param-value>
</init-param>
<load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>invoker</servlet-name>
    <url-pattern>/servlet/*</url-pattern>
</servlet-mapping>在前面调用时，假如你的servlet为com.db下dbCtrl.class,你的应用为app
用/app/servlet/com.db.dbCtrl进行访问

当然是用开发工具啦,Eclipse,JB都行,会自动帮你加的!

<?xml version="1.0" encoding="ISO-8859-1"?><!DOCTYPE web-app
    PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
    "http://java.sun.com/dtd/web-app_2_3.dtd"><web-app>
  <display-name>Welcome to Tomcat</display-name>

 <servlet>
        <servlet-name>test.Count</servlet-name>
        <servlet-class>test.Count</servlet-class>
        </servlet>
        <servlet-mapping>
        <servlet-name>test.Count</servlet-name>
        <url-pattern>/servlet/test.Count</url-pattern>
        </servlet-mapping>      
这是我root目录下的web.xml文件,按这样的配置,能运行test.Count,但新建个servlet文件就非的改web.xml吗,有没有办法使只改一次web.xml以后每次新建个servlet都能运行呢?
Count的servlet如下:
package test;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class Count extends HttpServlet
{ int count;
  public void init(ServletConfig config) throws ServletException
    {super.init(config);
     count=0;
    }
  public synchronized void service(HttpServletRequest request,HttpServletResponse response)
                             throws IOException
    { //获得一个向客户发送数据的输出流：
       PrintWriter out=response.getWriter();
       response.setContentType("text/html;charset=GB2312");//设置响应的MIME类型。
       out.println("<HTML> <BODY>");
        count++;                         //增加计数。
       out.println("you are "+count+"th"+" people");
       out.println("</body> </html>");
    }
}
谢谢你们的答复,可是还是没解决问题,希望继续指点.

这是我root目录下的web.xml文件,按这样的配置,能运行test.Count,但新建个servlet文件就非的改web.xml吗,例如新建一个test.Hello,就不改web.xml就没办法运行.有没有办法使只改一次web.xml以后每次新建个servlet都能运行呢?
Count的servlet如下:
package test;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class Count extends HttpServlet

  public void init(ServletConfig config) throws ServletException
    {super.init(config);
     count=0;
    }
  public synchronized void service(HttpServletRequest request,HttpServletResponse response)
                             throws IOException

       response.setContentType("text/html;charset=GB2312");//设置响应的MIME类型。
       out.println("<HTML> <BODY>");
        count++;                         //增加计数。
       out.println("you are "+count+"th"+" people");
       out.println("</body> </html>");
    }
}
