In Listing 18-3, the webflow-config-namespace is declared as the default namespace. Also, the faces
namespace is defined for JSF-related configurations.
First, the <flow-executor> tag defines an instance of the
org.springframework.webflow.executor.FlowExecutor interface, which is the central façade and entry-
point service interface into the Spring Web Flow system for driving the executions of flow definitions.
Second, the <flow-registry> tag defines a registry for the flow definitions within the application.
From the listing, the flow definitions are stored in files named flow.xml, under the parent folder /WEB-
INF/flows. For example, the file /WEB-INF/flows/contacts/flow.xml will store the flow definition for the
contact application.
The <faces:flow-builder-services> tag defines an instance of the
org.springframework.webflow.engine.builder.support.FlowBuilderServices class, with JSF integration,
which is required for Spring Web Flow when building the flows within the flow registry.
Finally, the bean with an ID of facesContextListener and the implementation class
FlowFacesContextLifecycleListener defines an instance of the
org.springframework.webflow.execution.FlowExecutionListener interface, which creates an instance of
the org.springframework.faces.webflow.FlowFacesContext class. The FlowFacesContext class extends
JSF's FacesContext abstract class (under the package javax.faces.context), which provides the context
for the underlying JSF 2 runtime environment.
