BlackBerry app unable to establish Http Connection with server


This is the code that I am using for an HTTP connection:

HttpConnection connection = null;
// InputStream inputstream = null;
connection = (HttpConnection) Connector.open("http://www.google.com");
//HTTP Request
connection.setRequestMethod(HttpConnection.GET);
connection.setRequestProperty("Content-Type","//text plain");
connection.setRequestProperty("Connection", "close");
add(new LabelField(""+connection.getResponseMessage()));
connection.close();

Solution

  • This BlackBerry Development Guide titled "Code sample: Creating a connection over HTTP by using the first available transport" worked!!

    ConnectionFactory connFact = new ConnectionFactory();
    ConnectionDescriptor connDesc;
    connDesc = connFact.getConnection("http://www.google.com");
    if (connDesc != null) {
        HttpConnection httpConn;
        httpConn = (HttpConnection)connDesc.getConnection();
        try { 
            final int iResponseCode = httpConn.getResponseCode();
            UiApplication.getUiApplication().invokeLater(new Runnable() {
                public void run() {
                    Dialog.alert("Response code: " + 
                        Integer.toString(iResponseCode));
                }
            });
        } catch (IOException e) {
            System.err.println("Caught IOException: " + e.getMessage());
        }
    }
