Cannot view reports on the web in 11g.

We have migrated from Application Server /Forms/Reports 10g to 11g. We have a forms and reports application. We can generate the reports through the forms application. They get generated on the server as .pdf documents. We cannot view them via the forms web application.  Please advise as to which reports /forms/Apache configuration files needs to be modified and configured. I already have a virtual directory set up in forms.conf in 11g.(this is all I had to do in 10g). It does not work in 11g. Pl help. Thanks.
