Hi Ken ,
I tried modifying your code as
NSURL *url = [NSURL URLWithString:@"http://www.apple.com";];
NSData *data; // data from the website
KHTTPSocket *socket = [KHTTPSocket socketWithURL: url];
id result = [socket send: @"testing 1, 2, 3"];
But when I run the code, I get the following error:
NSURLErrorDomain
Error Code : 1012
User info : 2 key/value paris
Please help me out.
THANKS,
DEEP

Hi Deep
I wrote this little class to encapsulate HTTPRequests using POST and
it's been working nicely for several months. It doesn't deal with
Java specifically, but it shouldn't require too many tweaks
@interface KHTTPSocket : NSObject
{
NSURL *url;
}
+ (id) socketWithURL:(NSURL *) inURL;
- (id) initSocketWithURL:(NSURL *) inURL;
- (id) send:(id) inData;
@end
@implementation KHTTPSocket
+ (id) socketWithURL:(NSURL *) inURL
{
return [[[KHTTPSocket alloc]
initSocketWithURL: inURL]
autorelease];
}
- (id) initSocketWithURL:(NSURL *) inURL
{
if (self = [super init])
{
url = [inURL retain];
}
return self;
}
- (void) dealloc
{
[url release];
[super dealloc];
}
- (id) send:(NSString *) inData
{
// serialize inData into PHP form
// NOTE: "query=" prefix is what the PHP script looks for in the
$_POST
// variable to see if there's anything for it to process
NSMutableURLRequest *request = [NSMutableURLRequest
requestWithURL: url];
const char *temp = [inData UTF8String];
NSData *body = [NSData dataWithBytes: temp length: strlen(temp)],
*result;
NSString *bodyLength = [[NSNumber numberWithInt: [body length]]
stringValue];
NSCharacterSet *returnChars = [NSCharacterSet
characterSetWithCharactersInString: @"\r"];
NSHTTPURLResponse *response;
NSError *error;
NSLog(@"php query string = %@", phpData);
// generate the HTTP POST
[request setHTTPMethod: @"POST"];
[request setValue: @"application/x-www-form-urlencoded"
forHTTPHeaderField: @"Content-type"];
[request setValue: bodyLength forHTTPHeaderField: @"Content-length"];
[request setValue: @"close" forHTTPHeaderField: @"Connection"];
[request setHTTPBody: body];
// send it away
result = [NSURLConnection sendSynchronousRequest: request
returningResponse: &response
error: &error];
NSLog(@"result = %@, error = %@", result, error);
// process result if any
if ((result != nil) && ([result length] > 0))
{
// You may need to change this part. I use it with PHP scripts that
return PList formatted data
NSString *temp = [[[NSString alloc] initWithBytes: [result bytes]
length: [result length]
encoding: NSUTF8StringEncoding]
stringByTrimmingCharactersInSet: returnChars];
return [temp propertyList];
}
else if (error != NULL)
{
// something went awry log HTTP header and error
NSLog(@"response = %@", [response allHeaderFields]);
NSLog(@"error = %@", error);
}
return nil;
}
@end
And to use it
KHTTPSocket *socket = [KHTTPSocket socketWithURL: inURL];
id result = [socket send: @"testing 1, 2, 3"]; // <- do something
with the data in your server side java
NSLog(@"result = %@", result);
