Objective C (iOS) to jersey query params. Null issue - ios

Question

I am learning Jersey and stumbling from one issue to another. I just got the service to work from Java client (after some help from someone here). The service class is as follows:
#Path("/user")
public class UserService extends AbstractService {
private static final NouLogger logger = NouLogger
.getLogger(UserService.class);
#Path("fbregister")
#POST
#Produces(MediaType.TEXT_HTML)
#Consumes(MediaType.APPLICATION_FORM_URLENCODED)
public String createNewFBUser(#FormParam("fbuserid") String userid,
#FormParam("fbmailid") String emailId,
#FormParam("fbfullname") String fullName,
#FormParam("fbusertoken") String userToken,
#Context HttpServletResponse servletResponse) throws IOException,
DatabaseException {
final String methodName = "createNewFBUser";
User user = new User();
user.setEmail(emailId);
user.setName(fullName);
user.setFacebookSecret(userToken);
Session session = null;
try {
session = getSession();
} catch (DatabaseException e) {
final String message = "Error occurred while fetching session.";
logger.error(methodName, message, e);
e.printStackTrace();
}
UserDAO userDAO = DAOFactory.DEFAULT.buildUserDAO();
Transaction txn = session.beginTransaction();
userDAO.save(user);
txn.commit();
closeSession();
return user.getId().toString();
}
}
This works fine when I call it from Java client. But when I call it from iOS code, I get all the null values for all the parameters. The iOS code is as below:
// To encode parameter.
NSString *fb_userid = [user objectForKey:#"id"];
NSString *fb_mailid = (NSString *)CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(NULL,(CFStringRef)[user objectForKey:#"email"], NULL, (CFStringRef)#"!*'();:#&=+$,/?%#[]",kCFStringEncodingUTF8 ));
NSString *fb_fullname = (NSString *)CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(NULL,(CFStringRef)user.name, NULL, (CFStringRef)#"!*'();:#&=+$,/?%#[]",kCFStringEncodingUTF8 ));
NSString *fbAccessToken = [[[FBSession activeSession] accessTokenData] accessToken];
NSLog(#"user = %#", user);
NSLog(#"fb_userid = %#", fb_userid);
NSLog(#"fb_mailid = %#", fb_mailid);
NSLog(#"fb_fullname = %#", fb_fullname);
// To send url Request.
NSString *url1 =[NSString stringWithFormat:#"http://myip:8080/nou/rest/user/fbregister?fbuserid=%#&fbmailid=%#&fbfullname=%#&fbusertoken=%#", fb_userid, fb_mailid, fb_fullname, fbAccessToken];
NSURL *url = [NSURL URLWithString:url1];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
[theRequest setHTTPMethod:#"POST"];
theConnection1 = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
Any idea why this is happening? I put it on remote debug, I could see the method being invoked also, my DB entry was created but all the null values were put in it. Help me solve this issue.
EDIT:
I tried sending just one parameter 'id' and it did not work either.

In your java code, you are accepting parameters as FormParam but while posting you are sending it as part of query string from the client code. So either:
Change the FormParam in server code to QueryParam
or Change the client code to send it as post params. Here is an example:
