# Deploying Endeca data source configuration on WAS 6.1

To configure one or more MDEX Engines as data sources for the Discovery Framework, a JSON configuration file needs to be deployed for each MDEX Engine.

These files should be deployed relative to the Liferay Home directory. Sample data source configuration files are provided as .json.sample files in the endeca-portal-dependencies-<version>.zip file you downloaded.

To deploy Endeca data source configuration:

Upload the files to the data/endeca-data-sources/ subdirectory. For example: /home/endeca/liferay/data/endeca-data-sources/default.json
