1、使用form表单 action对象可以是jsp、servlet 点击 submit后 地址改变 页面跳转

     
      	  name: 
       
      
      
	  password: 
      
      
      
	  
       
     

或者：

     
            name: 
       
      
      
      password: 
      
      
      
      
       
     

相应的servlet：

         
      
       tr
          
      
       tr
        
       
         
      
       tr
          
      
       /tr
        
     

 源程序：

public void doGet(HttpServletRequest request, HttpServletResponse response)			throws ServletException, IOException {		response.setContentType("text/html");		String uname = request.getParameter("nu1");			String upassword = request.getParameter("nu2");  		PrintWriter ou = response.getWriter();	        ou.println("userddd:     "+uname+"
");		ou.println("passdddword:     "+upassword+"
");		}
