i am new to Spring. I created a maven project in eclipse to test

  • 0

i am new to Spring. I created a maven project in eclipse to test Spring MVC by resembling the mvc-basic example from Spring example SVN repository. when i tried to retrieve model values in jsp, the jsp just displayed ${model attribute name}, not the model attribute value.

Do I miss anything making Spring failed to retrieve model value?

Below are the details:

code: controller:

@Controller
public class TestAction {

@RequestMapping(value="/test" , method=RequestMethod.GET)
public String returnHelloWorld(Model model)
{
    ObjectTest objectTest=new ObjectTest();
    objectTest.setName("heng");
    model.addAttribute(objectTest);
    return "/test/start";
}
 }

code JSP:

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>
<%@ taglib prefix="s" uri="http://www.springframework.org/tags" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"      "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
     hello ${objectTest.name}  
</body>
</html>

When running it on the server (tomcat 6)
the page displayed like

hello ${objectTest.name}

but should be

hello heng

here is the snapshot

enter image description here

Note:

I created a normal eclipse dynamic project and create the same controller , jsp and other component. and the jsp can retrieve the model value successfully.
here is the snapshot of the project and jars.

the difference is that this project has springframework.web.servlet jar
while the maven project has sprinng-webmvc jar

    the reason for the problem is EL is not enabled

    to enable EL, i changed the web.xml from

    <?xml version="1.0" encoding="UTF-8"?>
<!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>
 ....
 </web-app>

    to 

    <?xml version="1.0" encoding="UTF-8"?>
 <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee   http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
</web-app>
