Servlet的打包~~~

我编译了这两个类，其中HelloServlet3.java用到了ServletUtilities.java。两个类如下：
package coreservlets;
import javax.servlet.*;
import javax.servlet.http.*;
public class ServletUtilities {
  public static final String DOCTYPE =
    "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0 " +
    "Transitional//EN\">";  public static String headWithTitle(String title) {
    return(DOCTYPE + "\n" +
           "<HTML>\n" +
           "<HEAD><TITLE>" + title + "</TITLE></HEAD>\n");
  }package coreservlets;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class HelloServlet3 extends HttpServlet {
  public void doGet(HttpServletRequest request,
                    HttpServletResponse response)
      throws ServletException, IOException {
    response.setContentType("text/html");
    PrintWriter out = response.getWriter();
    String title = "Hello (3) I'm qdh!!";
    out.println(ServletUtilities.headWithTitle(title) + 
                "<BODY BGCOLOR=\"#FDF5E6\">\n" +
                "<H1>" + title + "</H1>\n" +
                "</BODY></HTML>");
  }
}编译好后，把这两个生成的class文件放入.../WEB-INF/classes/coreservlets/路径中，然后在浏览器中输入http://localhost:8080/servlet/coreservlets.HelloServlet3，可是每次浏览器中都出现HTTP Status 404 - Servlet test5 is not available
这个错误，web.xml中应该写入什么内容？希望得到高手们的解答，谢谢！

  1.   

    http://localhost:8080/servlet/coreservlets/HelloServlet3
      

  2.   

    http://localhost:8080/servlet/coreservlets/HelloServlet3
      

  3.   

    http://localhost:8080/servlet/coreservlets/HelloServlet3
      

  4.   

    http://localhost:8080/servlet/coreservlets/HelloServlet3这个试过了，还是不行啊，web.xml中应该怎么写？我的是这样写的：
    <?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> 
                <servlet>       
                    <servlet-name>test5</servlet-name>       
                    <servlet-class>HelloServlet3</servlet-class>       
              </servlet>       
              <servlet-mapping>       
                    <servlet-name>test5</servlet-name>       
                    <url-pattern>/servlet/coreservlets/HelloServlet3</url-pattern>       
              </servlet-mapping>  
    </web-app>   
    大家看看有没错。谢谢哦
      

  5.   

    http://localhost:8080/servlet/coreservlets/HelloServlet3
      

  6.   

    行了，原来的web.xml问题，正确的应该是：
    <?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> 
                <servlet>      
                    <servlet-name>test5 </servlet-name>      
                    <servlet-class>coreservlets.HelloServlet3 </servlet-class>      
              </servlet>      
              <servlet-mapping>      
                    <servlet-name>test5 </servlet-name>      
                    <url-pattern>/servlet/coreservlets.HelloServlet3 </url-pattern>      
              </servlet-mapping>  
    </web-app>  
    然后在浏览器中还是要输入http://localhost:8080/servlet/coreservlets.HelloServlet3
    问题解决了，谢谢大家~
