This guide is for developers who want to create their own Data Transformation widgets for Yellowfin. After development, widgets may be imported into Yellowfin using the plug-in manager. Developers may write their own Input, Transformation and Output widgets.


Setup Overview

These are the prerequisites for setting up the development environment for writing any Yellowfin plug-ins:

  • Set up your preferred IDE. The steps in this guide use Eclipse for EE developers.

  • Install the Tomcat plug-in for your IDE, if it’s not already included in the installation.

  • Install the version of Yellowfin to be used for development.

  • Start up Yellowfin to extract the WAR file.

    See our guide on the basics of developing plugins and steps.
