The Application Configuration property allows you to configure the connectivity and level parameters for an application that you have created, and without changing or rebuilding the application, deploy the same application into a different system. For example, you can take an application that is running in a test environment and deploy it to a production environment without rebuilding the application. A Composite Application's external connectivity parameters, which are normally defined in the WSDL service extensibility elements, can be configured in the runtime properties. For more information on using Application Configurations see Defining an HL7 Binding Component Application Configuration.
