title: Can't get JBoss to start, deployment missing
body: <p>I'm having this strange error with JBoss. It's strange because it's looking for some old projects that aren't even related to my current project and are also deleted from my workspace in eclipse.</p>
  
  <p>When I try to get the current project to run, I get this error:</p>
  
  <pre>
  DEPLOYMENTS MISSING DEPENDENCIES:
    Deployment "jboss.j2ee:ear=BibliotheekEAR.ear,jar=BibliotheekEJB.jar,name=Bibliotheek,service=EJB3" is missing the following dependencies:
      Dependency "" (should be in state "Described", but is actually in state "** UNRESOLVED Demands 'persistence.unit:unitName=BibliotheekEAR.ear/BibliotheekJPA.jar#BibliotheekJPA' **")
    Deployment "jboss.j2ee:ear=BibliotheekEAR.ear,jar=BibliotheekEJB.jar,name=Bibliotheek,service=EJB3_endpoint" is missing the following dependencies:
      Dependency "jboss.j2ee:ear=BibliotheekEAR.ear,jar=BibliotheekEJB.jar,name=Bibliotheek,service=EJB3" (should be in state "Configured", but is actually in state "PreInstall")
  
  DEPLOYMENTS IN ERROR:
    Deployment "" is in error due to the following reason(s): ** UNRESOLVED Demands 'persistence.unit:unitName=BibliotheekEAR.ear/BibliotheekJPA.jar#BibliotheekJPA' **
    Deployment "persistence.unit:unitName=BibliotheekEAR.ear/BibliotheekJPA.jar#BibliotheekJPA" is in error due to the following reason(s): org.hibernate.HibernateException: Hibernate Dialect must be explicitly set
  </pre>
  
  <p>Any ideas?</p>
  
  <p>I have deleted all these projects, so I don't know why it's looking for them...</p>
