Forms 6i is very old and no longer supported. Oracle DB 11 is very new. Win7 is very new.
Forms 6i was not supported for use with Oracle db 11 or Win7. With that in mind, in order to run Oracle Forms 6 web deployed, you will need to have Application Server version 220.127.116.11.x installed. This AS version is also very old and is no longer supported and therefore not supported with new databases or on new operating systems.
Also, you said "...how to configure ...", but provided a URL. Are you wanting to configure or run?
I want to develop a small app on a local server where students to be able to insert their name/surname, age and class to a competition. On oracle forms I just created the fmb file but I don't know how to get this online on our local server.
What I need is when someone go to http://localhost:7777/forms/frmservlet? for example to see that fmb and to be able to insert their details..
Hope this clear the things and you can help me with some details.
