.getResponseCode() hangs when trying to connect java(blackberry project) to webservice

Question

I am trying to connect to a webservice from my blackberry project in eclipse. My code for URLConnector is the following

import java.io.InputStream;
import javax.microedition.io.Connector;
import javax.microedition.io.HttpConnection;
import net.rim.device.api.ui.component.Dialog;


public class URLConnector 
{
HttpConnection con = null; 
InputStream is = null; 

public URLConnector()   {
    try 
    {
    Dialog.inform("1"); 
    String url = new String("https://webserviceBlahBlah");

    Dialog.inform(con.toString()); 
        int responseCode = con.getResponseCode(); 
        Dialog.inform("3"); 
        if (responseCode != HttpConnection.HTTP_OK) { 
            Dialog.inform("3.5"); 
            System.out.println(responseCode); 
        } 
        is = con.openInputStream(); 
        byte[] responseData = new byte[10000]; 
        int length = 0; 
        Dialog.inform("4"); 
        StringBuffer rawResponse = new StringBuffer(); 
        while (-1 != (length = is.read(responseData))) { 
            Dialog.inform("5"); 
            rawResponse.append(new String(responseData, 0, length)); 
        } 
        final String result = rawResponse.toString(); 
        System.out.println(result); 
        Dialog.inform("6"); 
    } 
    catch (Exception ex) 
    { 
        Dialog.inform("ex.getMessage()"); 
        System.out.println(ex.getMessage()); 
    } 
    finally 
    { 
        try { 
            is.close(); 
            is = null; 
            con.close(); 
            con = null; 
            Dialog.inform("8"); 
        } 
        catch(Exception e){
            Dialog.inform("e"); 
        } 
    } 
}

The application hangs on the con.getReponse() call. It is running on the blackberry 9800 simulator. Any help would be super appreciated because I am very stuck

Answer 1

James, I'm assuming after you turned the MDS Simulator on, you discovered that you also had a problem because you never opened the connection?

Anyway just to give a final working solution:

    HttpConnection con = null;
    InputStream is = null;
    try {
        System.out.println("1");
        String url = new String("http://myserver.com/index.html");

        //I added these two lines to your code and tested it with my own server and got a 200 RC.
        net.rim.device.api.io.transport.ConnectionFactory cf = new net.rim.device.api.io.transport.ConnectionFactory();
        con = (HttpConnection)cf.getConnection(url).getConnection();

        System.out.println(con.toString());
        int responseCode = con.getResponseCode();
        System.out.println("3 responseCode = " + responseCode);
        if (responseCode != HttpConnection.HTTP_OK) {
            System.out.println("3.5");
            System.out.println(responseCode);
        }

Also if you have to support BBJava 5.0 minus, you can have a look at : http://www.versatilemonkey.com/HttpConnectionFactory.java . It's not prefect but its a good place to start with creating connections for pre 5.0 platforms.
