Introduction
The previous versions of Pentaho Data Integration contained an experimental step called "Formula". This step is based on the experimental Pentaho Reporting library "LibFormula".
We have made this step available as a plugin because we fear not many people have used this step in the past.
Source code
The source code for the plugin is available under an LGPL license over here in Subversion.
Installation
The files attached to this page contain the required libraries to run and use this step.
Place all 3 files in the libext/ directory of your Pentaho Data Integration distribution. Version 3 or higher is required.
| jcommon-1.0.8.jar | 298 kb | JFree Commons core library, required by LibFormula |
| libformula-0.1.13.jar | 254 kb | The latest Pentaho Reporting LibFormula library. |
| formula3.jar | 23 kb | The annotated PDI plugin |

Can'T find the file "formula3.jar" on subversion following the link above. Can you help?
Click on "Page operations" on the left upper corner and you see "Attachments". I changed the site to clarify and added this link: http://wiki.pentaho.org/pages/viewpageattachments.action?pageId=2130081
Thanks,
Jens
I could not find the attachments mentioned here. I checked out the hyperlink on LibFormula but it pointed to a zip file which contains its own build.xml, lib folder etc. Can you please clarify the same please?
