Hi all,

I can connect to webservice using the simulator(using Research In Motion in background) but cannot via actual Black Berry device.

How do i go about connecting to web service using a Blackberry device.

Code:

try {
			int length = bodytext.getBytes().length;
			String contentlength = Integer.toString(length); 
			HttpConnection connection = (HttpConnection) Connector.open(webserviceurl,Connector.READ_WRITE,true);
			
			connection.setRequestProperty("SOAPAction", soapAction);
			connection.setRequestProperty("Content-Type", "application/soap+xml;charset=UTF-8");
    		connection.setRequestProperty("Content-Length",contentlength);
    		connection.setRequestProperty("User-Agent", "kSOAP/2.0");
    		connection.setRequestMethod(HttpConnection.POST);
    		OutputStream os = connection.openOutputStream();
    		os.write(bodytext.getBytes(), 0, bodytext.getBytes().length);
    		os.close();
    		bodytext = null;
    		InputStream is = connection.openInputStream();
    		XmlPullParser xp = new KXmlParser();
    		xp.setFeature(XmlPullParser.FEATURE_PROCESS_NAMESPACES, true);
    		xp.setInput (is, null);
    		envelope.parse(xp);
    		obj= (SoapObject) envelope.getResponse();
		} catch (IOException e) {
			System.out.println(e);
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (XmlPullParserException e) {
			System.out.println(e);
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		catch (Exception e) {
			System.out.println(e);
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

do you use any kind of connection suffix on your webservice url?
maybe http://www.blackberry.com/developers/docs/7.1.0api/net/rim/device/api/io/transport/ConnectionFactory... can help you out.

Agree with SImon.

To understand the connection suffix and the various connection paths that the BlackBerry can use, I recommend reviewing the following:

Hi Simon and Peter,

I have added a suffix to the url but still unable to connect to web service as connection fails

The phone picks up "Carrier coverage" and has "carrierUid". I also get a java.io.IOException error if this means anything

Code

Connection String

private static String getConnectionString()
    {
        // This code is based on the connection code developed by Mike Nelson of AccelGolf.
        // http://blog.accelgolf.com/2009/05/22/blackberry-cross-carrier-and-cross-network-http-connection
        String connectionString = null;
        System.out.println("Connection String:");
        // Simulator behavior is controlled by the USE_MDS_IN_SIMULATOR variable.
        if(DeviceInfo.isSimulator())
        {
        	System.out.println("Device is a simulator and USE_MDS_IN_SIMULATOR is false");
            connectionString = ";deviceside=false";   
        }

        // Wifi is the preferred transmission method
        else if(WLANInfo.getWLANState() == WLANInfo.WLAN_STATE_CONNECTED)
        {
        	System.out.println("Device is connected via Wifi.");
            connectionString = ";interface=wifi";
        }

        // Is the carrier network the only way to connect?
        else if((CoverageInfo.getCoverageStatus() & CoverageInfo.COVERAGE_DIRECT) == CoverageInfo.COVERAGE_DIRECT)
        {
        	System.out.println("Carrier coverage.");

            String carrierUid = getCarrierBIBSUid();
            if(carrierUid == null)
            {
                // Has carrier coverage, but not BIBS.  So use the carrier's TCP network
            	System.out.println("No Uid");
                connectionString = ";deviceside=true";
            }
            else
            {
                // otherwise, use the Uid to construct a valid carrier BIBS request
            	System.out.println("uid is: " + carrierUid);
                connectionString = ";deviceside=false;connectionUID="+carrierUid + ";ConnectionType=mdspublic";
            }
        }

        // Check for an MDS connection instead (BlackBerry Enterprise Server)
        else if((CoverageInfo.getCoverageStatus() & CoverageInfo.COVERAGE_MDS) == CoverageInfo.COVERAGE_MDS)
        {
        	System.out.println("MDS coverage found");
            connectionString = ";deviceside=false";
        }

        // If there is no connection available abort to avoid bugging the user unnecssarily.
        else if(CoverageInfo.getCoverageStatus() == CoverageInfo.COVERAGE_NONE)
        {
        	System.out.println("There is no available connection.");
        }

        // In theory, all bases are covered so this shouldn't be reachable.
        else
        {
        	System.out.println("no other options found, assuming device.");
            connectionString = ";deviceside=true";
        }

        return connectionString;
    }

[peter_strange]

This is not correct:

connectionString = ";deviceside=false;connectionUID="+carrierUid + ";ConnectionType=mdspublic";

Review this KB article to see what you should be specifying:

http://supportforums.blackberry.com/t5/Java-Development/Different-ways-to-make-an-HTTP-or-socket-con...

Also I recommend that you put MDS first - if you are being used on a corporate phone this is the best connection method - it will automatically swap to WiFi if WiFi is available.

Hi Peter,

I changed the connection string as follows: connectionString = ";deviceside=false;ConnectionUID="+carrierUid + "";

Is that correct because just get a error saying "IOException: Stream not in setup state".

I thought this was the WAP 2 connection method in which case the connection suffix is:

";deviceside=true;ConnectionUID=" + uid

not deviceside=false;....
