Hi! I'm working on an app that requires the user to log in. I'm trying to use HttpsConnection to submit the username and password to a website that will verify the username/password. I haven't been able to find any tutorials so I've been trying to piece together sample code I've found, but I really have no idea what I'm doing. When I run this code, the whole application just freezes. Any help would be greatly appreciated!

    void postViaHttpsConnection() throws IOException 
    {
        HttpsConnection c = null;
        int rc;
        String url = "https://www.loginwebsite.com";

        try 
        {
            c = (HttpsConnections)Connector.open(url);

            // set the request method and headers
            c.setRequestMethod(HttpsConnection.POST);
            c.setRequestProperty("id", "authenId");
            c.setRequestProperty("type", "text");
            c.setRequestProperty("name", "_authen_id");
            c.setRequestProperty("value", "00000000"); // THIS IS THE USERNAME
            c.setRequestProperty("size", "40");
            c.setRequestProperty("tabindex", "10");
            c.setRequestProperty("maxlength", "71");
            
            // getting the response code will open the connection, send the request, and read the HTTP response headers
            // the headers are stored until requested
            rc = c.getResponseCode();
            if (rc != HttpsConnection.HTTP_OK) 
            {
                throw new IOException("HTTP response code: " + rc);
            }
        } 
        
        catch (ClassCastException e) 
        {
            throw new IllegalArgumentException("Not an HTTP URL");
        }
    }

Like the app freezes, you can use System.out.println() in lines to see WHERE the app is locked. Maybe help to debug your app

Thanks. I know that the problem occurs in the following line:

c = (HttpsConnections)Connector.open(url);

Hi

One reason for the app freezing could be u running app on UI thread.
Perform this network checking and connection establishment in a separate Thread.

Try to implement the Transport Detective class to find out available transport and getFullURL funtion before opening the Https connection, since I referred the Peter's sample for https connection and it worked great for my https connection.
String _connectionURL = getFullURL(url, _transportType);
c = (HttpsConnections)Connector.open(_connectionURL);

private static String getFullURL(String requestedURL, int transport) {
        URLFactory urlFactory = new URLFactory(requestedURL);
        if ( (transport & TransportDetective.TRANSPORT_MDS) > 0 ) {
            return urlFactory.getHttpMdsUrl(false);
        } else
        if ( (transport & TransportDetective.TRANSPORT_TCP_WIFI) > 0 ) {
            return urlFactory.getHttpTcpWiFiUrl();
        } else
        if ( (transport & TransportDetective.TRANSPORT_BIS_B) > 0 ) {
            return urlFactory.getHttpBisUrl();
        } else
        if ( (transport & TransportDetective.TRANSPORT_TCP_CELLULAR) > 0 ) {
            // Only here for Simulator
            return urlFactory.getHttpDefaultUrl() + ";deviceside=true";
        } else {
            return urlFactory.getHttpDefaultUrl();
        }
    }

Good tips, guys! hannahb, and now? The connection works?
