How can I integrate a BIRT report in a web application?

system_migrated

I am looking for some basic steps on how to integrate the BIRT engine in a web application.

I have created some sample reports using Actuate BIRT Report Designer professional. This creates *.rptdesign.

How can I invoke and show this report from within my web application? The web application is hosted using weblogic and Oracle. Which jar files do I need to include in my web application project? Can some body point me to a tutorial for doing this?

Thanks much!
