PUT and POST getting 405 Method Not Allowed Error for Restful Web Sevices

I am trying to set up a simple Restful Web-Service which returns either JSON or XML according to the Accept header. I am using Spring, Maven and WebLogic Server. I took the example from this post http://software.sawano.se/2012/03/combining-json-and-xml-in-restful-web.html and tried to improve on it. GET and DELETE is working for both JSON and XML.But PUT and POST gives a "405 Method Not Allowed" Error. I am trying to test this with the Chrome Extension Advanced Rest Client. below is the Response headers.

the request body that i give is below:

{
id: 1
name: "manga"
}


My Controller Class is as shown below:

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.http.HttpStatus;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;

import java.util.HashSet;
import java.util.Set;

@Controller
@RequestMapping("/users")
public class RESTController {
Userlist obj2;
boolean flag=false;
private Logger logger = LoggerFactory.getLogger(getClass());

@RequestMapping(value = "/{id}",method = RequestMethod.GET)
@ResponseBody
public User getUser(@PathVariable int id, @RequestHeader("Accept") String acceptHeader) {
User temp = new User();
if(obj2==null)
{
temp= new User(0, "Null");
}
else {
Set<User> set1= obj2.getUsers();
for(User a:set1)
{
if(id==a.getId()) temp=a;
}
}
logger.trace("Serving resource for Accept header: {}", acceptHeader);
return temp;
}

@RequestMapping(value="",method = RequestMethod.GET)
@ResponseBody
public Userlist getUsers(){
if(flag==false){
User new1=new User(1,"Rob");
User new2=new User(2,"VAN");
User new3=new User(3,"DAM");
User new4=new User(4,"Helio");
Set<User> obj1 =new HashSet<User>();
obj1.add(new1);
obj1.add(new2);
obj1.add(new3);
obj1.add(new4);
obj2=new Userlist(obj1);
flag=true;
}
return obj2;
}

@RequestMapping(value="/{id}",method = RequestMethod.DELETE)
@ResponseStatus(HttpStatus.OK)
public void deleteUser(@PathVariable int id){
Set<User> set1= obj2.getUsers();
for(User a:set1)
{
if(id==a.getId()) set1.remove(a);
}
Userlist obj3=new Userlist(set1);
obj2=obj3;
//return obj3;
}

@RequestMapping(value="/{id}",method = RequestMethod.PUT, consumes = "Application/json")
@ResponseStatus(HttpStatus.OK)
public void updateUser(@PathVariable int id, @RequestBody User temp){
System.out.println("Inside the put function");
if(temp==null){System.out.println("This is a Null for PUT");}
}
}


Right now i do not have anything in PUT. Could you please let me know where i am going wrong? Thank you.

Answer

Well Apparantly i had to change my PUT calling function updateUser. I removed the consumes the the @RequestMapping and also added a @ResponseBody to the function. So my method looked like below.

@RequestMapping(value="/{id}",method = RequestMethod.PUT)
@ResponseStatus(HttpStatus.OK)
@ResponseBody
public void updateUser(@PathVariable int id, @RequestBody User temp){
    Set<User> set1= obj2.getUsers();
    for(User a:set1)
    {
        if(id==a.getId())
        {
            set1.remove(a);
            a.setId(temp.getId());
            a.setName(temp.getName());
            set1.add(a);
        }
    }
    Userlist obj3=new Userlist(set1);
    obj2=obj3;
}

and it worked!!!. Thank you all for the response.
