Oracle Reports-9i

Hi!

Could someone give me some simple assistance to write report in Oracle 9i.

I cannot purchase any reporting tool. I must either write it in JSP or use
a built-in Oracle function.

How can I write a simple Oracle report? Some idea should give me info how I
can build other reports.

Any on-line tutorial would be excellent. Please anything to get me started.

I would be most appreciated.

Thanks
Steve
