Hi guys,
I've got this design issue with reporting. You see, we have this 3rd party app (which we bought off the shelf) and it uses Oracle as the DB. Now, we initially wanted to use Crystal reports for the web reporting purposes. But, it sucks big time in terms of scalability and interoperability with EJBs and Solaris.
OK, since we got rid of Crystal, we thought of using java servlet and JSP to develop a reporting component. Now, we want the web user to login just once to this 3rd party app and be able to click a link which directs them to the web report query page. The trick is to make sure the user only views/reports his authorized data. This means the reporting portion has to make use of the 3rd party app's DAOs and security related java objects. OR alternatively we write our own security framework and DAOs to report directly off the Oracle DB.
Any comments?
Does anyone has any open source reporting framework out there that could accelerate this sort of work?

Hi Simon,
One open source report generator for Java is JFreeReport:

A couple of alternatives (JasperReports and Datavision) have links near the bottom of the JFreeReport page.
Maybe one of these will help a little...
