What is iReport?

iReport is a program that helps users and developers that use the JasperReports library to visually design reports.

Through a rich and very simple to use GUI, iReport provides all the most important functions to create nice reports in little time. iReport can help people that don't know the JasperReports library create complex reports and learn the XML syntax, taking a look to the generated code. iReport can help skilled report designers compose very complex pages, saving a lot of time. iReport is written in Java.

iReport is a visual designer for JasperReports. But What's JasperReports? JasperReports is the best (IMHO) open source reporting engine available for java community. It is developed by a small big genius called Teodor Danciu. JasperReports has always had one lack: it doesn't provide an adapted tool to visually design reports. JasperReports has hundred of features; possibilities of use are infinitely... a person that does not have much confidence with the XML could have some problems to take fully advantage from the JasperReports library.
