Problems opening http connection from blackberry simulator

Question

I'm having trouble when opening a simple HttpConnection from the simulator, I've have appended the deviceside=true suffix to my url, however it's still not working, I'm receiving an empty httpconnection with response code of 0. This is the code that's giving me problems:

public void readUrl(){
     HttpConnection conn=null;
        try {
            conn = (HttpConnection) Connector.open("http://www.google.com;deviceside=true");
            conn.setRequestMethod("GET");
             if(conn.getResponseCode()==HttpConnection.HTTP_OK){
                 System.out.println("Create connection sucessfully");
             }

        } catch (ConnectionNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (IllegalArgumentException e) {
            e.printStackTrace();
        }




        DataInputStream din=null;
        ByteVector responseBytes=null;
        try {
            din = conn.openDataInputStream();
             responseBytes = new ByteVector();
              int i = din.read();
              while (-1 != i) {
                responseBytes.addElement((byte) i);
                i = din.read();
              }
        } catch (IOException e) {
            //TODO: HANDLE EXCEPTIONS
            e.printStackTrace();
        }
        responseBytes.toArray();

I have no idea what's going on. It supposed that by appending the deviceside=true it should connect directly. Anyway I tried too installing the MDS server and setting my url to deviceside=false, but the result was the same.

Now I tested the same code using a local url like http://localhost:8080/resources/mypage.html, and It worked as expected, so I was wondering if this could be a simulator configuration issue. How can I solve it?

Thanks a lot.

In my experience, you need to append ;deviceside=true when using the MDS simulator. There's a great post on the blackberry.com forums that shows you how to determine what connection suffix you should be using, as well as some general good advice on using connections in BlackBerry.

For something to help make it easier to get the content of your request, you can use the IOUtilities class:

InputStream stream = conn.openInputStream();
String contents = new String(IOUtilities.streamToBytes(stream));
