The EAC Development Toolkit uses the Spring Framework's Inversion of Control container to load an EAC application based on configuration specified in an XML document.

A great deal of functionality and flexibility is provided in Spring's IoC Container and in the default bean definition XML file handled by Spring's XmlBeanDefinitionReader class. For details about either of these, refer to Spring Framework documentation and JavaDoc.

The EAC Development Toolkit uses a customized document format and includes a schema and custom XML handlers to parse the custom document format. It uses Spring to convert this customized configuration metadata into a system ready for execution. Specifically, the toolkit uses Spring to load a set of objects that represent an EAC application with the configuration specified for each object in the configuration document.
