FRM-10142 error message

Please explain the following error message: "FRM-10142: HTTP Listener is not running on rmurthy at port 8888. Please start the listener."

Please explain the following error message: "FRM-10142: HTTP Listener is not running on rmurthy at port 8888. Please start the listener."

This error may be happening because Forms 9i does not support client-server. A form run from the Forms Builder...

is a 'Web-deployed form.' To do this Forms 9i Builder needs to integrate with some form of HTTP Listener. This is provided by another component of the Oracle 9iDS Release 2 install -- the OC4J (Oracle Container For J2EE). If there is no HTTP Listener started, the FRM-10142 error will occur.

Once an OC4J instance has been started it acts as lightweight HTTP Listener enabling the developer to test the forms/reports application modules in a true Web (even if only intranet) architecture.

  • Start the OC4J instance:
    • In the Start menu click StartProgramsOracle 9i Developer SuiteReports DeveloperStart OC4J Instance, or find and run the startinst.bat file in your Dev 9i home. It is usually in Dev9i homej2eeOracle9iDS.
    • On MS Windows a command window should appear indicating that an OC4J instance has been started; simply minimize this command window to the taskbar.
  • Then try running the form again from Forms Builder.
  • Having finished with Forms Builder, to stop the OC4J instance:
    • Use the Stop OC4J Instance shortcut, located in the same place as the Start shortcut, or close the command window that you had minimized previously.
