Unable to call REST service with POST method

[mohana krishna]

I am implementing AsyncTask to consume a REST service.
When I invoke the service I am getting the error java.io.FileNotFoundException: https://www.testurl.in/service.php.
Can you please help me what is wrong with this code.

        protected Void doInBackground(String... params) {

            BufferedReader reader = null;
            try {

                URL url = new URL(params[0]);
                String urlParameters  = "service=forgot&email=[e-mail]&id=007";
                byte[] postDataBytes       = urlParameters.getBytes("UTF-8");

                HttpURLConnection conn = (HttpURLConnection) url.openConnection();
                conn.setRequestMethod("POST");
                conn.setRequestProperty("Content-Type", "application/text");
                conn.setRequestProperty("Content-Length", String.valueOf(postDataBytes.length));
                conn.getOutputStream().write(postDataBytes);
                //conn.connect();

                reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
                StringBuilder sb = new StringBuilder();
                String line = null;

                while ((line = reader.readLine()) != null) {
                    sb.append(line);
                }
                resultText = sb.toString();

            } catch (Exception ex) {
                Log.e("ATTEST", "Error is :" + ex.toString());
            } finally {
                try {
                    if(reader!=null)
                    reader.close();
                } catch (Exception ex1) {
                    
                }
            }

            return null;
        }

I am getting the error

Can you post the full stack trace that shows where the error happened?
Add a call to printStackTrace to get the stack trace.

Hi Norm Radder,

Thanks for your reply.I am getting exception at line number 17 when i run in debug mode.

reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));

           
tried with ex.printStackTrace(); to print stace strace buy i can not see message in Android monitor or Android device monitor log cat.

Strange the stack trace does  not show in the logcat.  Where did you add the call to the printStackTrace?  All catch blocks should have the call.

Hi Norm Radder,

Finally i am able to solve the issue , also i am able to read print stack trace.

I modified the code to read status of the response.

int status =conn.getResponseCode();
if(status<400){
	reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
	//read response
}else{
	reader = new BufferedReader(new InputStreamReader(conn.getErrorStream()));
	//read response
}

With the above code i came to know that request is not reaching the REST web service.
So i modified the URL with the service name with following code modification system is working as expected.

URL url = new URL("https://www.anytraining.in/service.php?service=forgot");
String urlParameters  = "email=[e-mail]&id=118";
byte[] postDataBytes       = urlParameters.getBytes("UTF-8");

Thanks for your prompt replies.

Regards,
Mohan.
