I've worked out an implementation with some inspirations from SpringMVC with application of FrontController pattern to Servlets. https://github.com/sshams/Entitlement
There are three major integration points to connect the Servlet (Router) to the PureMVC apparatus.
1. ServletContextListener on contextInitialized instantiates the ShellFacade and passes servletContextEvent to startup. StartupCommand
then instantiates modules (and plumbs) and registers them with the ServletContext using attributes.https://github.com/sshams/Entitlement/blob/master/src/Application.java
2. common/PipeAwareModule includes acceptRouter
function which then sends out the notification with router in it's body. RouterMediator
responds to this notification to and sets the router as it's viewComponent
and sets itself as a Delegate.
3. Servlet (Router) on init
method retrieves it's related Module from Servlet Content and calls acceptRouter
and passes itself.https://github.com/sshams/Entitlement/blob/master/src/modules/entitlement/view/components/Router.java
Each additional module will have it's own Servlet/Router defining it's own set of URI's and will receive the Router via acceptRouter
just like above.
So far it worked out fine but I'm open to any ideas, any other strategies that can polish it further from you or the community.
