BlackBerry Httpconnection post to a .Net Webservice not working on device

Question

I am developing an application to use httpconnection to get some data to a .Net Webservice. The code is working fine when i host the webservice locally and test it with Eclipse simulator, but when i host the webservice on the public deployment server and package the Blackberry app to my device all am getting is is a respose code 500. Please can someone give me a clue, an answer or a solution to what migth be causing this?

Below are the code i used:

String URL = WebServiceURL+"/Login"+getConnectionParameter();

public static String getConnectionParameter() {
    String ConnectionParameter ="" ;
    if (WLANInfo.getWLANState() == WLANInfo.WLAN_STATE_CONNECTED) {
        // Connected to a WiFi access point
        ConnectionParameter = ";interface=wifi";
    } else {
        int coverageStatus = CoverageInfo.getCoverageStatus();
        ServiceRecord record = getWAP2ServiceRecord();
        if (record != null && (coverageStatus & CoverageInfo.COVERAGE_DIRECT) == CoverageInfo.COVERAGE_DIRECT) {
            // Have network coverage and a WAP 2.0 service book record
            ConnectionParameter = ";deviceside=true;ConnectionUID="+ record.getUid();
        } else if ((coverageStatus & CoverageInfo.COVERAGE_MDS) == CoverageInfo.COVERAGE_MDS) {
            // Have an MDS service book and network coverage
            ConnectionParameter = ";deviceside=false";
        } else if ((coverageStatus & CoverageInfo.COVERAGE_DIRECT) == CoverageInfo.COVERAGE_DIRECT) {
            // Have network coverage but no WAP 2.0 service book record
            ConnectionParameter = ";deviceside=true";
        }
    }
    return ConnectionParameter;
}

URLEncodedPostData oPostData = new URLEncodedPostData(
                URLEncodedPostData.DEFAULT_CHARSET, false);
                oPostData.append("username",username.getText());
                oPostData.append("compressedpicture",HomeScreen.convertByteArrayToString(imageArray));
                oPostData.append("email",email.getText());
                oPostData.append("password",password.getText());
                oPostData.append("pin",pin.getText());
                oPostData.append("extension",extension);
                String URL = MYAPP.WebServiceURL+"/SignUp"+MYAPP.getConnectionParameter();
                String result = HomeScreen.postinfo(URL,oPostData);
                Dialog.inform(result);
                if(result.indexOf("success")!= -1){
                    Dialog.inform("You Have just sign up. Congratulations.");
                }else{
                    Dialog.inform("There is an issue registering you"); 
                }




public static String postinfo(String _URL,URLEncodedPostData _PostData) {
    String result = "";
    try {
        HttpConnection conn = (HttpConnection) Connector.open(_URL,
                Connector.READ_WRITE);
        if (_PostData != null) {
            conn.setRequestMethod(HttpConnection.POST);
            conn.setRequestProperty("Content-type",
                    "application/x-www-form-urlencoded");
            conn.setRequestProperty("Content-Length",
                    Integer.toString(_PostData.size()));
            OutputStream strmOut = conn.openOutputStream();
            strmOut.write(_PostData.getBytes());
            strmOut.close();
        } else {
            conn.setRequestMethod(HttpConnection.GET);
        }

        int responseCode = conn.getResponseCode();
        if (responseCode == HttpConnection.HTTP_OK) {
            InputStream data = conn.openInputStream();
            StringBuffer raw = new StringBuffer();
            byte[] buf = new byte[4096];
            int nRead = data.read(buf);
            while (nRead > 0) {
                raw.append(new String(buf, 0, nRead));
                nRead = data.read(buf);
            }
            result = raw.toString();
            //Dialog.alert("Result:" + raw.toString());
            //_Dest.updateDestination(raw.toString());
        } else {

            _Dest.updateDestination("responseCode="
                    + Integer.toString(responseCode));
            result = "responseCode= "+ Integer.toString(responseCode);
        }
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        //_Dest.updateDestination("Exception:" + e.toString());
        result = "Exception:" + e.toString();
    }
    return result;
}

Thanks for all your suggestion Guys. I appreciate them all. I discovered my production server was throwing the internal server error 500 because of of the /WebserviceMethod at end of my URL e.g.

String URL = WebServiceURL+"**/Login**"+getConnectionParameter();

I found a solution using KSOAP2. It worked perfectly well. Though u might av to write some lines of code to handle the parsed response format(KSOAP2 return a parsed format of the response XML).

Am sure you will find the article at this link useful: KSoap Android Web Service Tutorial With Sample Code

It applies to most J2ME based mobile platform.

Once again Thank you all for your time and help.
