Upon installation, all components that require a backing data source are bound to a data source called default.json. This file does not exist by default; you must either manually create it under endeca-portal\data\endeca-data-sources, or switch to another data source in the Framework Settings component.
This task leads you through creating a default.json file based on the simplest possible model.
To create a default.json file:
{ "server":"localhost", "port":"8080" }
After you have established your default.json file, you can log on to the Discovery Framework and begin building your application by adding components.
