# ColdSpring XML Reference

Model-Glue:Unity introduces the ColdSpring.xml file to the Application Template.

This file replaces the <config> block that was at the top of 1.x ModelGlue.xml files.

It acts as a place to both configure your application and define additional beans accessed through the GetBean() method of the Model-Glue API.

By default, it contains two beans:

1. ModelGlueConfiguration - the settings for the Model-Glue framework instance in your application. Each setting is explained in the "Model-Glue Configuration Setting Definitions" section of this reference.

2. ReactorConfiguration - if the Reactor framework is installed (necessary for automated database access and scaffolding), these are the settings that will be used to configure Reactor in place of a <config> block at the top of Reactor.xml. Each setting is explained in the "Reactor Configuration Setting Definitions" section of this reference.
