Pentaho Design Studio

The Pentaho Design Studio is an Eclipse-based development environment used to enrich report distribution and end user interaction. It enables report scheduling, e-mail distribution, dynamic and static prompting, and more.

The Eclipse wiki, and especially the FAQ pages, include much information on how to use and troubleshoot Eclipse (and hence the Design Studio).

For tips on integration of the design studio (xaction files) with the report designer (prpt files), refer: Report Designer (Flow)
