The Spring BlazeDS Integration is very simple.
The flex:message-broker initializes BlazeDS
and it's configuration files, which by default are expected in '/WEB-INF/flex' and for the main configuration to be called
'services-config.xml'. Two services are loaded, 'personDao' and 'personService'. It's not best practice to expose the DAO directly as a service, but
for this example it was done to illustrate exposing a remoting service using annotations and the custom namespace.
One from the context:component-scan and the other is
exposed using the Spring BlazeDS Integration custom namespace.
The PersonService exposed through scanning will be shown later in the Code Example section,
and the JPA Person DAO is exposed using flex:remoting-destination. It's created just by referencing
the Person DAO. To have a remoting destination name other than the bean name the destination-id could specify something different.
