How to store a table's data from oracle database into an excel file?

Hi,
I am doing a small application using JSP, Servlets, Oracle DataBase express edition.
In this, I store some data into a particular table of the database from the application. The user of the application wants the data from that table to have it stored in an excel file.
To be specific, I have to provide an option for the user to delete a particular "vehicle" under operation from the application after its agreement expires. But the user wants all the data in an excel file.
How do I do it?

Some applications solve this by pushing a .csv file to the user.
This extension is usualy associated with Excel (if they have MSOffice installed).

Another solution is to build real Excel files. You could use Apache POI.
The POI project consists of APIs for manipulating various file formats based upon Microsoft's OLE 2 Compound Document format using pure Java. In short, you can read and write MS Excel files using Java.

And (works in my setup XP with Excel 2003):
Create a file with extension .xls, and write the contents as tab delimited values. It opens in excel as if it was a real excel document.

I understood that I should use Apache POI API for my application in order to convert database tables to excel.
Do I need to do any pre-configuration for that? like writing an xml file... or any such kind of stuff??
and one more thing.. how do I get the javadocs download for Apache POI?

The Displaytag library (http://displaytag.sourceforge.net) has options to output to Excel.
