| <div class="paragraph"> |
| <p>This sample implements a simple polling application.</p> |
| </div> |
| <div class="paragraph"> |
| <p>You can create polls and then vote (+1 or -1) for each poll (called Subject).</p> |
| </div> |
| <div class="paragraph"> |
| <p>The front is a JAX-RS front and the backend uses EJBs and JPA.</p> |
| </div> |
| <h1 id="_module" class="sect0">Module #</h1> |
| <div class="paragraph"> |
| <p>The application contains several modules:</p> |
| </div> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>polling-domain: entities used by the client side too</p> |
| </li> |
| <li> |
| <p>polling-core: the middle/dao layer</p> |
| </li> |
| <li> |
| <p>polling-web: front layer (REST services)</p> |
| </li> |
| </ul> |
| </div> |
| <h1 id="_what_is_noticeable" class="sect0">What is noticeable #</h1> |
| <div class="paragraph"> |
| <p>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 ;)).</p> |
| </div> |
| <div class="paragraph"> |
| <p>It manages a dynamic datasource too. It manages in the example configuration 2 clients.</p> |
| </div> |
| <div class="paragraph"> |
| <p>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.</p> |
| </div> |
| <h1 id="_client" class="sect0">Client #</h1> |
| <div class="paragraph"> |
| <p>It lets you create poll, retrieve them, find the best poll and vote for any poll.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Please type help for more information.</p> |
