RestKit Post method with JSON

I'm developing an iOS App for school. I'm using a database so i can run some statistics later. I created a Restful Web Service to handle all functions I need and using RestKit to access the Web Service. When I need to retrieve data from WS i dont have any problem to do it, but when i need to post info I am getting some errors that I would like some help if you can.

The POST method I created in WS is for adding a new Collection to DB, it has no return, just add it. I'm using the GSON library to convert from JSON. I tested with the "tester" from netbeans and worked well so I guess the problem is not on the Web Service. I'll put the code for the classes involved and the method that is trying to POST de object.

I have this class: Collection

#import <Foundation/Foundation.h>
#import "User.h"
@interface Collection : NSObject
@property NSNumber *idCollection;
@property NSString *name;
@property User *user;
@property NSArray *collectionItens;
@end

And this class: User

#import <Foundation/Foundation.h>
@interface User : NSObject
@property NSNumber *idUser;
@property NSString *login;
@property NSString *password;
@end

Both class only have the @syntezise

Here is the method im trying to post the object:

- (IBAction)createNewCollection:(id)sender
{
NSLog(@"..");
Collection *collection = [[Collection alloc] init];
collection.name = collectionNameTextField.text;
collection.user = [AppDefauts defaultUser];

RKObjectMapping *userMapping = [RKObjectMapping requestMapping];
[userMapping addAttributeMappingsFromArray:@[ @"idUser", @"login", @"password"]];

RKObjectMapping *collectionMapping = [RKObjectMapping requestMapping];
[collectionMapping addAttributeMappingsFromArray:@[ @"idCollection", @"name"]];

[collectionMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:@"user" toKeyPath:@"user" withMapping:userMapping]];



RKRequestDescriptor *requestDescriptor = [RKRequestDescriptor requestDescriptorWithMapping:collectionMapping objectClass:[Collection class] rootKeyPath:@"collection" method:RKRequestMethodAny];


RKObjectManager *objectManager = [RKObjectManager managerWithBaseURL:[NSURL URLWithString:@"http://localhost:8080/MTGAppWS/webresources"]];
[objectManager addRequestDescriptor:requestDescriptor];

[objectManager postObject:collection path:@"/Collection"    parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
    NSLog(@"Success");

} failure:^(RKObjectRequestOperation *operation, NSError *error) {
    NSLog(@"Error");
}];
}

Log display on Xcode with error:

Web Service code for include a new Collection

@Path("Collection")
public class CollectionService
{
}
@Context
private UriInfo context;

/**
 * Creates a new instance of CollectionService
 */
public CollectionService()
{
}
@PUT
@Consumes("application/json")
public void createNewCollection(String content)
{
    CollectionController c= new CollectionController(new SQLController());
    Gson gson = new Gson();
    JsonParser parser = new JsonParser();
    parser.parse(content);
    Collection collection = gson.fromJson(content, Collection.class);
    c.criarNovaCollection(collection);

}

}

EDIT

Found out that the request wasn't "going" to right address.

already fixed that but now its happening another error. (Method not allowed).

The server you are communicating with is giving you an HTML error page instead of the JSON you were expecting: The requested resource () is not available. The error isn't in your app (unless you are asking for the wrong URL); it's on the server.
