About

The g2 Report Engine is an open source reporting framework that integrates with your Java/J2EE application to produce reports. The project focuses on creating a simple, easy to use API that implements the majority of required reporting features.

A report can be executed directly from Java in 1 line of code... it doesn't get any easier!

HTMLReportBuilder.build(inputFile,params,outputFile);

Why another reporting engine, you ask? I need a reporting engine that can ultimately live inside Google App Engine (GAE) or any other "restricted" platform that I may choose. Rather that wait around for the possibility of an existing project to support GAE I thought I would build my own. As of 5/21 I have added some basic support for JDO-based App Engine queries, see the App Engine Support section.

The only down side to building your own Reporting Engine is having to create a GUI report designer... if you have any suggestions for this let me know!
