Looking for a framework for print output and more

I’m looking for a Java tool that can produce print output for web applications. What should it be able to do and support?

• A user-friendly tool (a graphical designer) for creating report layouts
• A sensible way to process returned data
• HTML and PDF output formats
• Integration and management within web applications
• Easy integration and deployment in the application server

The idea is that the reports will be prepared by ordinary users who don’t know Java as well as by specialists. That makes it very important for the framework to have a graphical template designer, preferably with localization support.

So far I’ve only looked at open-source tools and came across the widely recommended JasperReports. Unfortunately I haven’t tested it yet, so if you use JasperReports I’d be interested in your observations.

Of course, I’d also welcome any other experiences and tips on Java reporting tools.
