Send/receive data to a server using Cocoa

Hi All

I am new to Cocoa Development.
I am trying to modify the currency converter application to work as a
client server model.
For this I have used JBoss server as the backend and I am trying to
send two inputs from the Cocoa UI to the server and get the conversion
back to the UI from JBoss.
I have been trying to achieve this by using NSURLConnection and
NSURLRequest. My code is as follows:

NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL
URLWithString:@"http://145.36.149.31:8080/CBuild/servlet/HelloAddition?input1=4&input2=6"]
                                               cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0];
                                                   // create the connection with the request
   // and start loading the data
   NSURLConnection *theConnection=[[NSURLConnection alloc]
initWithRequest:theRequest delegate:self];
   if (theConnection) {
       // Create the NSMutableData that will hold
       // the received data
       receivedData=[[NSMutableData data] retain];

Though we are not getting any error message we cannot get any data in
the variable receivedData.

Am I missing anything here?

Please advice.

Thank you
