could anyone help me with the code.
i'm putting the code here but when i'm using this the server is geting
a null value.
if something can be done in tis code itself or if something else can
be suggested.
#import "ConverterController.h"
@implementation ConverterController
- (IBAction)convert:(id)sender
{
int num1,num2;
num2 =[dollarField floatValue];
num1 = [rateField floatValue];
NSNumber *number1 = [NSNumber numberWithInt:num1];
NSNumber *number2 = [NSNumber numberWithInt:num2];
NSString* tempurlstring;
NSString* URLString;
NSString* resultString;
NSMutableData *receivedData=nil;
unsigned char *firstBuffer,*buffer;
NSURLConnection* theConnection;
int stringlen;
tempurlstring = [NSString
stringWithCString:"http://145.36.149.31:8080/CBuild/servlet/HelloAddition";];
NSString *inputs;
NSString *tempinputs;
tempinputs = [NSString stringWithCString:"input_1="];
inputs = [tempinputs stringByAppendingFormat:@"%@ &input_2=%@",
number1,number2];
NSMutableURLRequest *postURLRequest=[NSMutableURLRequest
requestWithURL:[NSURL URLWithString:tempurlstring]
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0];
[postURLRequest setHTTPMethod:@"POST"];
[postURLRequest setValue:@"text/xml" forHTTPHeaderField:@"Content-type"];
NSData *data = [NSData dataWithBytes:inputs length:[inputs length]];
[postURLRequest setHTTPBody:data];
theConnection=[[NSURLConnection alloc] initWithRequest:postURLRequest
delegate:self];
if (theConnection)
{
receivedData=[[NSMutableData data]retain];
}
firstBuffer = [receivedData mutableBytes];
resultString = [NSString stringWithCString:firstBuffer];
[amountField setStringValue:resultString];
