How to pass a json object as a parameter to the webservice?
===

I have to use a webservice which takes json object as parameter. Here's my code:
NSStrring * x= @"{\"GetVehicleInventory\": {\"ApplicationArea\": {\"Sender\": {\"ComponentID\":}}}" (something like that)

NSStrring * sample = [NSString stringWithFormat:@"https://trialservice.checkitout?XML_INPUT=%@",x];
NSMutableRequest * request = [NSMutableREquest requestWithURL:[NSURL URLWithString:sample]];

When i am trying to NSlog sample its give me the complete URL which on pasting on browser give me result back but when i am doing NSlog for request, it shows null and nothing happend after this.
The control never goes to its NSURLConnection delegate method.

Please help.
Thanks,
