Hi Ranchers,
I have posted the same topic on Spring forum earlier, but did not get any response. Hence I am writing it here as well.

I am trying to complete step by step Spring MVC tutorial and am stuck at part 4 where business logic is referred from the Controller.

When I try to print the values present in the objects returned by the controller, the string

${beanName.property}

is displayed on the screen.

My jsp is :

and my controller :

package springapp.web;

import java.io.IOException;
import java.util.HashMap;
import java.util.Map;

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

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

import springapp.service.ProductManager;
				
public class InventoryController implements Controller {

protected final Log logger = LogFactory.getLog(getClass());

ProductManager productManager;

public ModelAndView handleRequest(HttpServletRequest request,
			HttpServletResponse response) throws ServletException, IOException {

Map myModel = null;
		try {
			logger.info(" Returning hello view to :: hello.jsp");
			String now = "Now String";
			myModel = new HashMap();
			myModel.put("now", now);
			myModel.put("products", this.productManager.getProducts());
			System.out.println(this.productManager.getProducts());
			System.out.println(now);
		} catch (Exception e) {
			logger.info(e.getMessage());
		}
		//return new ModelAndView("/jsp/test.html");
		 return new ModelAndView("hello", "model", myModel);

}

public void setProductManager(ProductManager productManager) {
		this.productManager = productManager;
	}
}

The unit tests for all the beans and controller run successfully :
package test.springapp.web;

The aplication-servlet.xml follows :

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

Please guide me to a direction following which I can identify my mistake.

I tested my bean injections. I instantiated the bean "/hello.htm" and the injections are working:

The test follows :

and the values are present in the required beans.
Hence I suspect there's a problem with my jsp .

It's not interpreting EL in your JSP pages. Check your WEB-INF/web.xml deployment descriptor - make sure it matches the correct specification to the web app container you are using. And make sure you're using a web app container that supports Servlet spec 2.4 or higher.
