title: Sw architecture - Comunication between java modules
body: <p>I have to make an app in java defined in a multi module maven project that will be executed in a jboss server.</p>
  
  <p>The app's modules will be defined in the parent pom file this way:</p>
  
  <pre><code>.................
  &lt;module&gt;dbModule&lt;/module&gt;
  &lt;module&gt;securityModule&lt;/module&gt;
  &lt;module&gt;auditoryModule&lt;/module&gt;
  ..........
  </code></pre>
  
  <p>And the question is :
  How can be made the comunication btw modules?With ejbs?Is there any sample?</p>
  
  <p>Thanks!</p>
