Funny thing about Oracle Reports, is that it is run through a Servlet to get the reports. If you have Oracle Reports, aren't your running Oracle Forms? If I remember Oracle Reports creates PDFs, so If you just wanted access to them then you just point to the PDF, although Oracel gives them undistinguishable filenames.
Have you thought about going through MetaLink, posting a question on how to call the Reports Servlet to generate a report directly in a Web Page? They should have the best information and even some white papers showing you how to do it.
