Oracle Forms Runtime error
This is Weblogic. The FORMS services are actually answered by a Weblogic Java Server. It is named WLS_FORMS and you can start it via the web logic management console (available by default as http://localhost:7001/console).

Click on the servers link on the left, then on the main pane, select "Control" tab. Select the checkbox next to WLS_FORMS and select "Start listening".
