To invoke an application in Oracle Forms using URL, you must configure it in formsweb.cfg file. Then you would be able to access it by providing config parameter is equal to your application name. Below I am giving an example to configure formsweb.cfg to run Oracle Forms application. This configuration is valid for Oracle Forms 10g/11g.
formsweb.cfg Configuration Example
[yourappname] workingDirectory=c:\serverdir\ userid=yourid/psw@orcl form=mainform.fmx
Save the changes in formsweb.cfg file and then access it as follows.
Run Oracle Forms Application
http://localhost:8889/forms/frmservlet?config=yourappname
You can see above the application URL using the config parameter with your application name [yourappname], you defined in formsweb.cfg file using square brackets [].
