Can I have some suggestions on creating a excel spreadsheet from Birt?

<p>My Environment is a glassfish 4 server. The example birt application doesn't work on this version of the server unless I change the url to use preview instead of frameset. How would you guys go about exporting a report to .xls file using birt? I am open to all suggestions. But my ideal setup would be to have one .war project, run it on glassfish 4, and have it convert the report in the background and the user just clicks the button and it is prompted to save the report as xls file. But again I am open to any suggestion that results in using birt, and ends with a excel spreadsheet with some data pulled from the database.</p>
