Spring link navigation problem

[Jagdev Singh]

I am new to spring mvc.I am learning spring-mvc using spring 2.5.6.I am using simpleformcontroller to login into application.After successful login it shows the users home page,here user have populated user command from database.In user home page there are some links to other secure pages.

Now my target is to navigate the links and when user redirect to the desired page.It should have populated user command one that page.

Now my problem is how to send user command from user home page to the target(desired) page when user click the particular link.
How this can be solve using spring 2.5.6.

Thanks in advance.

I would do something like below.

1) Create SimpleController class. Override handleRequest method. In that method get your command objects from the user home page and add to ModelView Object.

package com.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

public class SimpleController implements Controller {

	public ModelAndView handleRequest(HttpServletRequest req,
			HttpServletResponse arg1) throws Exception {
		

		// get command object form the user home page.
		Object command = req.getAttribute("command");
		
		// give the next page name in constructor.
		ModelAndView model =  new ModelAndView("hello");
		//set command object in the model object.
		model.addObject("command", command);
		
		return model;
		
	}

2. In Jsp use follow code to get the command object set in the controller. I assume all your views are jsp pages.

<% Map x = (Map)request.getAttribute("data") %>
