I’ve created an e-book reader app & it supports in-app-purchase. The transaction receipt which gets generated is being sent to a jboss server. The following piece of code has been written to send the transaction receipt to server. here i’m converting .xml file to NSdata & passing the NSdata object to server. 

-(IBAction)download:(id)sender{
    NSString *XMLPath = [[NSBundle mainBundle] pathForResource:@"ebook" ofType:@"xml"];

    NSString *name = @"photo1"; 
    NSData *imageData = [NSData dataWithContentsOfFile:XMLPath];
    NSLog(@"size of imageDATA %d",imageData.length);
    //NSString *Datastring = [NSString strin]
    NSString *dataString = [[NSString alloc] initWithData:imageData encoding:NSUTF8StringEncoding];
    //transaction.transactionReceipt;
    //NSData * imageData = UIImagePNGRepresentation(image); 
    // NSString *postLength = [NSString stringWithFormat:@"%d", [imageData length]];        
    NSString *urlString = @"http://172.18.11.162:8080/DRM_15April/ReceiptDownload";
    //urlString = [urlString stringByAppendingString:@"tranReceipt"];
    //urlString = [urlString stringByAppendingString:@"&name="];
    //urlString = [urlString stringByAppendingString:name]; 
    //urlString = [urlString stringByAppendingString:@"&lang=en_US.UTF-8"]; 
    NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
    [request setURL:[NSURL URLWithString:urlString]];
    NSLog(@"the url is %@",urlString);
    [request setHTTPMethod:@"POST"];
    NSMutableData *postBody = [NSMutableData data];



    //add data field and file data
    [postBody appendData:[NSData dataWithData:imageData]];
    NSLog(@"size of DATA %d",postBody.length);
    // ---------

    [request setHTTPBody:postBody];

    // now lets make the connection to the web
    NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
    NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];

    NSLog(@"return strind is %@",returnString);

}

This is logging the following in my console window.

-[KitabooBookShelf download:] the url is http://172.18.11.162:8080/DRM_15April/ReceiptDownload

    You trying to read an XML data with an ObjectInputStream, but as the javadoc says:

    An ObjectInputStream deserializes primitive data and objects previously written using an ObjectOutputStream.

    So actually there is nothing wrong on client side, but on server side.
