If your BlackBerry device is associated with a BlackBerry® Enterprise Server and uses an HTTPS proxy server that requires authentication, you will not be able to use end-to-end TLS.

1. Import the following classes:
   • net.rim.device.api.system.CoverageInfo
   • javax.microedition.io.Connector
2. Import the following interfaces:
   • net.rim.device.api.system.CoverageStatusListener
   • javax.microedition.io.HttpsConnection
3. Use the CoverageInfo class and CoverageStatusListener interface of the net.rim.device.api.system package to make sure that the BlackBerry device is in a wireless network coverage area.
4. Invoke Connector.open(), specifying HTTPS as the protocol and cast the returned object as an HttpsConnection object to open an HTTP connection.

   HttpsConnection stream = (HttpsConnection)Connector.open("https://host:443/");

5. To specify the connection mode, add one of the following parameters to the connection string that passes to Connector.open()
   • Specify that an end-to-end HTTPS connection must be used from the BlackBerry device to the target server: EndToEndRequired
   • Specify that an end-to-end HTTPS connection should be used from the BlackBerry device to the target server. If the BlackBerry device does not support end-to-end TLS, and the BlackBerry device user permits proxy TLS connections, then a proxy connection is used: EndToEndDesired.

   HttpsConnection stream = (HttpsConnection)Connector.open("https://host:443/;EndToEndDesired");
