Hi everybody,
Today i have played around with JasperReports. Really nice java tool to created very easy reports. I did not find many examples on internet. Therefor I post my first try. I hope this will help other developers starting up with this great tool.
This example runs a query (JDBC connected) with some parameters define in Java. The result is converted to PDF and then zipped.

Hi,
I recommend you to use DynamicReports (http://dynamicreports.sourceforge.net), is based on Jasperreports and you can create reports very easy and fast
