Reports, creating them, running them, distributing them - are the bane of every developers, users, and administrators existance. But people LOVE their reports. Many commercial solutions exist to try and ease the agony of report creation and management; most famously (or notoriously) is "Crystal Reports". Open Reports is the Open Source answer to reporting. Using the renowned Jasper reports format and libraries Open Reports provides a power report server that runs reports on the server side, while letting you develop reports in a client-side GUI assemble-it manner. And not just any reports, but beautiful and colorful reports. Output can be delivered right to a user's browser window as PDF, to their desktop as XLS, or as plain old CSV - all from the same report. Access to reports can be restricted (on the server!) to certain users and groups - and just for kicks a powerful schedular is built in too.
