The onCreate event fires when the report item is being created by the report engine’s generation task. The onRender event fires when the report item is being rendered by the report engine’s render task. These events and example are described on the BIRT website. Some report ite... (more)

Below are just some of the resources that have been posted to BIRT Exchange that should help you with cubes and crosstabs. Introduction Resources To get an idea of what a BIRT cube is and how to tie it to a crosstab report item, take a look at this article which provides a detailed write-up of the technology and supplies some examples. To see a recorded demonstration of a crosstab style report being build s... (more)

Java Feature — Developing an Eclipse BIRT Report Item Extension

The Eclipse platform is an Open Source, integrated system of application development tools that you implement and extend using a plug-in interface. Eclipse provides a set of core plug-ins that configures the basic services for the platform's framework. A platform developer can build and integrate new tools in this application development system. Business Intelligence Reporting Tool (BIRT) is a set of plug-in extensions that lets a developer add reporting functionality to an application. The APIs in BIRT define extension points that let the developer add custom functionality to t... (more)
