Question

what i am trying to do is, i am creating a very simple iphone app, textfield and a button that when pressed it should send the text in the text field to a servlet hosted locally (glass fish 3.1.1) and just to make sure the request is done i type a simple

system.out.println("Request received");

and each time i hit the button and i go to check the server log, it empty !
i tried the same url in the browser then check the log,”Request received” is in the log.

the method connected to the button is:

-(IBAction) connectToServer:(id)sender{
NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://localhost:8080/Test/Home"]];
NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
}

i really dont know if i am missing any thing here, any help ??

Answer 1

You haven’t started the connection

So, your action’s method should look like:

- (IBAction)connectToServer:(id)sender {
    NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://localhost:8080/Test/Home"]];
    NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
    [theConnection start];
}

Or, you may use a different initializer:

- (IBAction)connectToServer:(id)sender {
    NSURLRequest *theRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://localhost:8080/Test/Home"]];
    [NSURLConnection connectionWithRequest:theRequest delegate:self];
}

Or

- (IBAction)connectToServer:(id)sender {
    NSURLRequest *theRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://localhost:8080/Test/Home"]];
    [[NSURLConnection alloc] initWithRequest:theRequest delegate:self startImmediately:YES];
}
