This figure shows the request flow through Oracle Application Server Forms Services. The request is sent from a client to the Oracle HTTP Server. mod_oc4j sends the request to the Forms Listener Servlet in OC4J. The request then goes to Oracle Application Server Forms Services, where the Forms Runtime Process sends the request to the database. The response is then delivered from the database back through Oracle Application Server Forms Services, through OC4J, through Oracle HTTP Server, back to the client.
