Summary

 

This article applies to the BlackBerry® 8707 smartphone.

 


Problem

 

The BlackBerry 8707 smartphone running BlackBerry® Device Software 4.1.x does not support direct Hyptertext Transfer protocol (HTTP) or TCP/IP connections to the Internet using a wireless service provider’s gateway. If an application is attempting a direct HTTP or TCP/IP connection, the following error appears:

Protocol not found: null

 

Note: This error indicates that the protocol is not supported.

Resolution

 

Complete one of the following options:

  • Update the BlackBerry Device Software. Check your wireless service provider’s web site for updated BlackBerry Device Software.
  • For the HTTP connection to the Internet, the application needs to be leveraged to use the BlackBerry® Enterprise Server. For more information on how to leverage BlackBerry Enterprise Server connections, see the BlackBerry Application Developer Guide Volume 1 or the Javadoc™ for javax.microedition.io.Connector.
  • If you do not have a BlackBerry Enterprise Server, the application needs to be modified to use the BlackBerry® Internet Service gateway that is hosted by Research In Motion. Currently, the BlackBerry Internet Service connection model is only available to registered BlackBerry Alliance Program partners. For more information on joining the BlackBerry Alliance Program, see the BlackBerry ISV Alliance Program web site.

Additional Information

 

As a member of the BlackBerry Alliance Program, you receive development, marketing, and sales support, access to beta programs, and the BlackBerry Internet Service connection service.
