How to set PDF as default renderer in jasperserver?

Hi,

I've tried to search on this forum, on google and so on and not found any good solution how to display a report in PDF as default and not the HTML view, which I have figured out is the jasperviewer.

I've read that you could create your own jsp page and set that in the report unit. Tried that but with no success because I don't really know what the jsp page should contain.

Also read that you could change the viewReportFlow.xml to skip parts but no luck there either.

Anyone that have a good example?
