[Java][Jboss]classToLaunch cannot be null
<p>I'm beginner (Java/JBOSS), and I'm trying to launch JBOSS on Java EE, but I got always same error when I launch the server from Eclipse :</p>

<p><strong>With JBOSS 7.1.1</strong></p>

<blockquote>
  <p>An internal error occurred during: "Starting JBoss 7.1 Runtime Server".
  classToLaunch cannot be null</p>
</blockquote>

<p><strong>Or with JBOSS EAP 6.1.0</strong></p>

<blockquote>
  <p>An internal error occurred during: "Starting JBoss EAP 6.0 Runtime Server".
  classToLaunch cannot be null</p>
</blockquote>

<p>When I configure Server runtime environment, I have choice with :</p>

<ul>
<li>[JBoss Community]<em>JBoss 7.0 Runtime</em> or <em>JBoss 7.1 Runtime</em></li>
<li>[JBoss Enterprise Middleware]<em>Jboss Enterprise Application Platform 6.x Runtime</em></li>
</ul>

<p>One thing import think : I can't have internet connection where i'm installing the server (but I can copy from my local machine)</p>

<p>Versions :</p>

<ul>
<li>Eclipse Java EE, Kepler Release 2 (Build id: 20140224-0627)</li>
<li>jboss-as-7.1.1.Final</li>
<li>jboss-eap-6.1</li>
</ul>
