= Polling

== Sample

This sample implements a simple polling application.

You can create polls and then vote (+1 or -1) for each poll (called
Subject).

The front is a JAX-RS front and the backend uses EJBs and JPA.

== Module

The application contains several modules:

* polling-domain: entities used by the client side too
* polling-core: the middle/dao layer
* polling-web: front layer (REST services)

== What is noticeable

The front layer contains a MBean managed by CDI (VoteCounter) which is
used by REST services to update information you can retrieve through JMX
protocol (JConsole client is fine to see it ;)).

It manages a dynamic datasource too. It manages in the example
configuration 2 clients.

It is a simple round robin by request. That’s why from the client if you
simply create a poll then find it you’ll not find the persisted poll,
you need to do it once again.

== Client

It lets you create poll, retrieve them, find the best poll and vote for
any poll.
