Hello all,
I'm trying to get started in a little BB programming, and my first task is to make a HTTPS connection to a server, but the below code (which I took from an example on these forums) does not work for me, either on the simulator or on my actual BB 8800.

When run, I get my "Could not connect...", but the printing of the stack trace simply says "no stack trace", which is not very helpful.

Can anyone show me the error of my ways? Code is paste below. Note that I've taken out the actual URL as this forum will not let me post a link if I've got fewer than 10 posts under my belt, and I guess the parser has not noticed that the URL is in the CODE tags.

Cheers

Garry

 public void createConnection() {
                StreamConnection s = null;
                HttpsConnection connection = null;
                OutputStream outputStream = null;
                String result = new String();
                String httpConnString = new String();
                try {

                        httpConnString = "the URL goes here";
                        connection = (HttpsConnection) Connector.open(httpConnString);

                        connection.setRequestMethod(HttpsConnection.POST);

                        outputStream = connection.openOutputStream();

                        outputStream.write(httpConnString.getBytes());


                        InputStream inputStream = connection.openInputStream();
                        byte[] responseData = new byte[10000];
                        int length = 0;
                        StringBuffer rawResponse = new StringBuffer();
                        while (-1 != (length = inputStream.read(responseData))) {
                                rawResponse.append(new String(responseData, 0, length));
                        }

                     

                   
                        int responseCode = connection.getResponseCode();
                        if (responseCode != HttpConnection.HTTP_OK) {
                                throw new IOException("HTTP response code: " + responseCode);
                        }

                        
                         result = rawResponse.toString();
                         net.rim.device.api.ui.component.Dialog.alert(result);

                } catch (Exception e) { 
                    net.rim.device.api.ui.component.Dialog.alert("Could not connect...");
                    e.printStackTrace();
                 }   
    }

[Ivanov]

which exception is it?

Dialog.alert("Could not connect... " + e + ": " + e.getMessage());

[thegman]

Hi Ivanov,
Thanks for taking the time to help, here is the response I get:

Could not connect... java.io.IOException: Failed to transmit: Failed to transmit

That's on the simulator.

Any ideas?

Cheers

Hi

I am facing similar problem while using https and POST method if i use GET method it wrks fine, but i need POST.

Does anyone have any ideas.

try to change HttpsConnection to HttpConnection but provide the https:// protocol in the connection string.

[ggovind]

I have problem in GET method also. My ConnectionOpen(url) Times out in BB Bold. I'm sure this is something to do with the device/service setup, because the code works fine in my simulator for the same URL.

First when running on the simulator make sure you also have the MDS simulator running. Second HTTP transactions have to happen off the main execution thread.

Here is a code snippet from one of my apps that pulls objects off a queue and reports the content via HTTP GETs to a server.

 private class HttpThread extends Thread
 {
        ...
        public void run()
        {
            int returnCode = 0;
            try
            {
                while (outputQueSize() > 0)
                {
                    String returnContent, returnContentType;
                    
                    Object obj = peekOutputQue();
                    if (obj instanceof TrackPosition)
                    {
                        String url = makeUrl((TrackPosition)obj);
                        HttpConnection http = (HttpConnection)Connector.open(url);
            
                        returnCode = http.getResponseCode();
                        String returnMessage = http.getResponseMessage();
                        InputStream in = http.openInputStream();
                        
                        returnContentType = http.getType();
            
                        int cl = (int)http.getLength();
                        if (cl > 0)
                        {
                            byte[] buf = new byte[cl];
                            in.read(buf);
                            returnContent = new String(buf);
                        }
                        else
                        {
                            StringBuffer sb = new StringBuffer();
                            byte[] buf = new byte[1024];
                            int n = 0;
                            
                            while ((n = in.read(buf)) > 0)
                            {
                                sb.append(new String(buf,0,n));
                            }
                            returnContent = sb.toString();
                        }
                        
                        in.close();
                        http.close();
                    }
                    dequeueOutput();
                }
            }
            catch (Exception e)
            {
                System.err.println(e.toString());
                System.err.println(e.getMessage());
            }
            
            System.out.println(returnCode);
            done = true;
        }
    }
 }

Also, remember that unless you specify deviceside=true HTTPS connections are established from the Rim Operations Centre, which may not be what you want, and my not work depending on your server certificate. If you do set deviceside=true, then you may also need to set the APN on the device at Options -> Advanced Options -> TCP.

For the string URL, just use https://<blah blah> .. Make sure you have your MDS server running.

import java.io.InputStream;

import javax.microedition.io.Connector;
import javax.microedition.io.StreamConnection;

public class HTTPClient {
	public static String getPage(String url) {
		String response = "";

		try {
			StreamConnection s = (StreamConnection)Connector.open(url);

			InputStream input = s.openInputStream();

			byte[] data = new byte[256];
			int len = 0;
			StringBuffer raw = new StringBuffer();

			while( -1 != (len = input.read(data))) {
				raw.append(new String(data, 0, len));
			}

			response = raw.toString();

			input.close();
			s.close();
		} catch(Exception e) { }

		return response;
	}
}

Do i need to make any changes in the MDS config file to enable HTTPS POST
