title: WELD-001408 Unsatisfied dependencies for type ... with qualifiers [@Default] at injection point
body: <p>I got a stupid problem when deploying my Java Application on JBoss. Before I changed my source code using an interface class everything was fine. So here is my problem:</p>
  
  <pre><code>public interface FWInterface {
     public FWResult process(FWRequest fwRequest, FWResult fwResult,
                             Integer commitRows) throws Exception;
  }
  </code></pre>
  
  <p>...</p>
  
  <pre><code>@Stateless
  public class FWHandlerSqrMind extends FWHandlerDefault implements FWInterface {
  
     public FWResult process(FWRequest fwRequest, FWResult fwResult, Integer commitRows)
                     throws Exception {
                  ... some JavaCode here
     }
  }
  </code></pre>
  
  <p>This ends up with the following Error at deployment on JBoss 7.1:</p>

  <p>If I remove the implementation everything is ok. Could anybody tell me what the problem is? Am I too stupid?? Thanks in advance!</p>
