First of all make your local machine to act as a server for Forms and Reports.
This can be done by mentioning the report server name as 'localhost' or your system IP address and mentioning your port,report service name and report source name in your main form.
Then Start OC4j instance on your machine.
And while you run your forms through web browser ensure that the servername : (your port id)/ is given correctly.
Hope it will help you.
Steps to take.
(1.) In command prompt type RWSERVER SERVER=repserver1 to star the rep server.
(2.) If you get "Javaw.exe The procedure entry point psoasyn could not be located in the dynamic link library orapls10.dll." error do one of the following

or, if it does not work
(b.) Add D:\OracleDevR2\bin to the system env. variable PATH
(3.) Start OC4j
(4.) Now you can access the jobs using URL like:
where 22.214.171.124 is your machine's IP address.
