These are my source codes,
In the package 'controller' I have two classes,
package controller;
/**
*
* @author Personal
*/
public class Name {
private String value;
/**
* @return the value
*/
public String getValue() {
return value;
}
/**
* @param value the value to set
*/
public void setValue(String value) {
this.value = value;
}
}
and,
package controller;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.SimpleFormController;
import service.HelloService;
/**
*
* @author Personal
*/
public class HelloController extends SimpleFormController {
private HelloService helloService;
public HelloController() {
//Initialize controller properties here or
//in the Web Application Context
setCommandClass(Name.class);
setCommandName("name");
setSuccessView("helloView");
setFormView("nameView");
}
//Use onSubmit instead of doSubmitAction
//when you need access to the Request, Response, or BindException objects
@Override
protected ModelAndView onSubmit(Object command) throws Exception {
Name name = (Name)command;
ModelAndView mv = new ModelAndView(getSuccessView());
mv.addObject("helloMessage", helloService.sayHello(name.getValue()));
return mv;
}
public void setHelloService(HelloService helloService) {
this.helloService = helloService;
}
}
And in the package 'service' I have the following bean,
package service;
/**
*
* @author Personal
*/
public class HelloService {
public String sayHello(String name) {
return "Hello " + name + "!";
}
}
And these are my configuration files,

On the other hand I have two JSPs.
For the input,
<%@taglib uri="
http://www.springframework.org/tags" prefix="spring" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Enter Your Name</title>
</head>
<body>
<h2>Enter Your Name</h2>
<spring:nestedPath path="name">
<form action="" method="post">
Name:
<spring:bind path="value">
<input type="text" name="${status.expression}" value="${status.value}">
</spring:bind>
<input type="submit" value="OK">
</form>
</spring:nestedPath>
</body>
</html>
And for the output,
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Hello</title>
</head>
<body>
<h2>${helloMessage}</h2>
</body>
</html>
In the properties of the project I have in the node run set the following,
Context Path: /HelloSpring (the project name)
Relative URL: /hello.htm
Thanks in advance,
