Java app store receipt validation

I am trying to validate an Apple App Store receipt from a Java service. I can not get anything back other than an error 21002, "Receipt Data Property Was Malformed". I have read of others with the same problem, but, have not see a solution. I thought this would be fairly straight forward, but, have not been able to get around the error. Here is my code:
EDIT By making the change marked // EDIT below, I now get an exception in the return from the verifyReceipt call, also makred //EDIT:
String hexDataReceiptData = "<30821e3b 06092a86 4886f70d 010702a0 .... >";
// EDIT
hexDataReceiptData = hexDataReceiptData.replace(">", "").replace("<", "");
final String base64EncodedReceiptData = Base64.encode(hexDataReceiptData.getBytes());
JSONObject jsonObject = new JSONObject();
try
{
jsonObject.put("receipt-data",base64EncodedReceiptData);
}
catch (JSONException e)
{
e.printStackTrace();
}
URL url = new URL("https://sandbox.itunes.apple.com/verifyReceipt");
HttpURLConnection.setFollowRedirects(false);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoOutput(true);
//Send request
OutputStreamWriter wr = new OutputStreamWriter(connection.getOutputStream());
wr.write(jsonObject.toString());
wr.flush();
//Get Response
BufferedReader rd =
new BufferedReader(new
InputStreamReader(connection.getInputStream()));
StringBuilder httpResponse = new StringBuilder();
String line;
while ((line = rd.readLine()) != null)
{
httpResponse.append(line);
httpResponse.append('\r');
}
wr.close();
rd.close();
// EDIT
// {"status":21002, "exception":"java.lang.IllegalArgumentException"}

As posted here: Java and AppStore receipt verification, do the base64 encoding in iOS and send to the server. But, why?

Http post request to php script

I have a java program which makes an http post request to a php script on my website. Here is the code. I am also using the new Apache HTTP Components API. Here is a link to the download -> http://hc.apache.org/downloads.cgi
public static void main(String args[]) throws ClientProtocolException, IOException
{
HttpPost httppost = new HttpPost("http://ftstoo.com/public_html/TheFinalTouchSecurity/Database/test.php");
List<BasicNameValuePair> parameters = new ArrayList<BasicNameValuePair>();
parameters.add(new BasicNameValuePair("name", "Cannon"));
httppost.setEntity(new UrlEncodedFormEntity(parameters));
HttpClient httpclient = new DefaultHttpClient();
HttpResponse httpResponse = httpclient.execute(httppost);
HttpEntity resEntity = httpResponse.getEntity();
// Get the HTTP Status Code
int statusCode = httpResponse.getStatusLine().getStatusCode();
// Get the contents of the response
InputStream in = resEntity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(in));
StringBuilder out = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
out.append(line);
}
System.out.println(out.toString()); //Prints the string content read from input stream
reader.close();
}
}
My test.php file is located at http://ftstoo.com/public_html/TheFinalTouchSecurity/Database/test.php
Here is my php code.
<?php
$name = $_POST['name'];
echo "Success, . $name . !";
?>
The output I am getting when I run the java program is the html from a redirecting page on my website that says the page does not exist. I want the output to return a string that says "Success, Cannon!" I think there are probably several things I am doing wrong, but if someone could please give me a hand I would really appreciate it!

Corrupted Json in Android Eclipse

im having a strange problem when receiving json results from the server. I have no idea what the problem is. The thing is that my String json result is corrupted, with strange symbols.
The result is like this (taken from eclipse debug)
Image :
Another strange thing that happens is that when I change the URL of the service to an alternative one, it works and the data is not corrupted. The URLs are the same but once redirects everything to the other.
The URL is use always is (example) http://www.hello.com
The URL that works is http://www.hello.com.uy
(cant post the exact link for security reasons)
The second one redirects everything to the first one, its the only thing it does.
I have tried changing the encoding to UTF-8 and it is still not working, here is the code (with one of the URLs commented)
I have also tried using Dev HTTP Client extension from chrome to check the service and it works fine, no corrupted data. Also, it works perfectly on iOS so i think its just and android/java issue.
DevClient:
try {
JSONObject json = new JSONObject();
HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams, 10000);
HttpConnectionParams.setSoTimeout(httpParams, 10000);
HttpClient client = new DefaultHttpClient(httpParams);
//String url = TAG_BASEURL_REST +"Sucursal";
String url = "http://www.-------.com/rest/Sucursal";
//String url = "http://www.--------.com.uy/rest/Sucursal";
HttpGet request = new HttpGet(url);
request.setHeader("Accept", "application/json");
request.setHeader("Content-type", "application/json");
HttpResponse response = client.execute(request);
HttpEntity entity = response.getEntity();
if (entity != null) {
InputStream is = entity.getContent();
BufferedReader reader = new BufferedReader(
new InputStreamReader(is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
String jsonRes = sb.toString();
JSONArray jObj = new JSONArray(jsonRes);
return jObj;
}
} catch (Throwable t) {
Log.i("Error", "Request failed: " + t.toString(), t);
}
return null;

InputStream is = entity.getContent();
// check if the response is gzipped
Header encoding = response.getFirstHeader("Content-Encoding");
if (encoding != null && encoding.getValue().equals("gzip")) {
is = new GZIPInputStream(is);
}

extra \ in json response before every / in java, android

My code to get image Urls
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(new UrlEncodedFormEntity(params));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
InputStream inputStream = httpEntity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream, "iso-8859-1"), 8);
StringBuilder stringBuilder = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
stringBuilder.append(line + "\n");
}
inputStream.close();
return stringBuilder.toString();
where server code is in php
But problem is there is extra \ before every /
e.g. in database image Url is, http://www.dvimaytech.com/markphoto/upload/herwadeshirish123#Gmail.com/Pic.jpg
but I get every time http:\/\/www.dvimaytech.com\/markphoto\/upload\/herwadeshirish123#Gmail.com\/Pic.jpg
Is this problem isn't solvable, then another solution(its last option for me) is to remove every .
But when I try that using url = url.replace("\","");
it gives syntax error String literal is not properly closed by a double-quote

Just use a JSON parser library like gson to decode your JSON packets for you.
http://code.google.com/p/google-gson/
It will make your life much easier and avoid having to string.replace() specific characters.

You can use the following method to handle that
public static String extractFileName(String path) {
if (path == null) {
return null;
}
String newpath = path.replace('\\', '/');
int start = newpath.lastIndexOf("/");
if (start == -1) {
start = 0;
} else {
start = start + 1;
}
String pageName = newpath.substring(start, newpath.length());
return pageName;
}

Get web content

I'm trying to get XML content from an URL:
HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet();
request.setURI(new URI("http://www.domain.com/test.aspx"));
HttpResponse response = client.execute(request);
in = response.getEntity().getContent();
When I write out the response content, this is truncated before the end of the content.
Any idea?

Did you use a InputStreamReader for the input stream in?
String s = "";
String line = "";
BufferedReader rd = new BufferedReader(new InputStreamReader(in));
try {
while ((line = rd.readLine()) != null) { s += line; }
} catch (IOException e) {
// Handle error
}
// s should be the complete string

maybe i have solved, was the android emulator. Simply restarting it all works fine.
Thanks to all
