I created the code below but I seem to get the following error "No mapping found for HTTP request with URI [/restspring/service/employees/1] in DispatcherServlet with name 'restspring'" when I access the service using "http://localhost:8080/restspring/service/employees/1". Did I miss something?

Your help is kindly appreciated.
Thank You.
I think you are missing some steps as given in this document.
You need to define two beans
<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/>
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>
and then add a component scan for the controller path
ex
<context:component-scan base-package="org.springframework.samples.petclinic.web"/>
What is the name of the resulting war file? By default, that constitutes your context root and should be added to your request before the /service/employees/1 in your request url. The <servlet-name> of your web.xml is just a logical name for mapping a request (identified by the <url-pattern>) to a specific servlet, it is not a part of the url. Try omitting it when you make a request.
I don't see a component scan to detect your controller . If you have missed it , put it in . Sample
<context:component-scan base-package="org.myProject.controller"/>
This detects the #Controller annotation and also auto enables the <context:annotation-config> to process the annotations.
Check the link at http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/mvc.html#mvc-ann-controller for more info .

In my Spring MVC project I can't access to the parameters of bean with scope=session.Into Http session there is a bean with name "scopedTarget.user" .I want to print, in jsp page, the User's name.Why is it so difficult to access to this parameters?Where am I wrong?
ControllerHome:
#Controller
public class ControllerHome {
#Autowired
private User user;
#RequestMapping(value="/",method=RequestMethod.GET)
public String welcome(ModelMap model){
model.addAttribute("utente", user);

HttpSession session=request.getSession();
Enumeration<String> list=session.getAttributeNames();
while(list.hasMoreElements())
System.out.println(list.nextElement());

If you add these anotations #Component and #Scope(value = "session", proxyMode = ScopedProxyMode.TARGET_CLASS) to the POJO you want to be managed in a session, you can then use it in the JSP using the method you spoke of in your question (and Autowire it in your controllers). Make sure of two things though:
Don't override the toString(), otherwise it's that result that will be assigned to ${sessionScope['scopedTarget.user'].
Your POJO, in this case User, needs to be "caught" by the Spring's component scanner

When I run this web app as per my knowledge it should print "Raj" to the console but it doesn't print it. I have also tried to debug the app but still it is not going to the controller class.
Is there any mistake for mapping controller?
change your controller to:
*all other imports
import org.springframework.web.servlet.ModelAndView;
#Controller
public class homeController {
#RequestMapping("/home")
public ModelAndView homeManage(HttpServletRequest req,HttpServletResponse res) throws SQLException, ServletException, IOException{
System.out.println("Raj");
return new ModelAndView("home");
}
}
According to my previous question integration of jsf2.0 and spring 3.1 and hibernate 4.1
I think my code has problem. I am really confused. I did as other advised but still getting error 404:Description The requested resource (/jsfspringhiber/default.xhtml) is not available. I don't use maven.

Lets do one thing, Here is the code for a basic skeleton for integrating Spring and JSF. If you are able to see the login page with this code then we will build the solution out of this.
Create a new Dynamic Web Project with the following files:

And finally the backing bean: UserBean.java
package com.examples;
import java.io.Serializable;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Component;
#Component
#Scope("request")
public class UserBean implements Serializable {
private static final long serialVersionUID = 1L;
private String name;
private String password;
public String getName() { return name; }
public void setName(String newValue) { name = newValue; }
public String getPassword() { return password; }
public void setPassword(String newValue) { password = newValue; }
}
That's it, nothing more. Just copy and paste this code into a sample project and lets see what we can do later. One more thing I noticed is that your lib folder under WEB-INF seems empty. You will need the following jars to run this project:
Download Latest GA release of Spring Framework from here and include the jars in the dist folder of the zip file.
Download JSF jars from here, you can grab the latest 2.1.10.
Include commons-logging jar from here
i use maven. the correct answer is here.
the structure is:
I'm trying to build an application using Spring MVC and Maven 3.0 within Eclipse using the webapp. I'm not able to get to the initial page, or navigate to any other pages from there w/out getting a 404 error. Please let me know if there's something I'm missing. Thanks!

Answer to the questions:
This is the code I'm using.
The #Controller annotation must be there.
As I said before I get :
HTTP Status 404 - /guard_weblayer/ type Status report message /guard_weblayer/
description The requested resource (/guard_weblayer/) is not available.
Apache Tomcat/7.0.25
I use a restfule design, a domainlayer, datalayer and weblayer. Can it effecting the weblayer?
You might want to start over and use an example from springbyexample. It contains everything you need in a understandable fashion (and its in maven as well.)
Most likely that's easier than debugging the current code.
