Halogen is an olap client viewer based primarily on OLAP4J and Google Web Tookit (GWT). Halogen is designed to fill a void in the availability of web based olap tools and as such was written in GWT.

Although Halogen is not officially a Pentaho product, but several key Pentaho developers are the initiators of the project.


In its early stage of development, Halogen has several features that may be of our interests.
  • The ability to connect to Mondrian's cube
  • Visually add dimension and measures from a chosen cube
  • Execute MDX query
  • Graphical Chart

Where to Download ?
