Can't get JBoss to start, deployment missing

Question

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.

When I try to get the current project to run, I get this error:

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

Any ideas?

I have deleted all these projects, so I don't know why it's looking for them...

Answer 1

It seems that you haven't set the Hibernate database dialect property correctly for the database your using in your application. Try setting your database dialect in your persistence.xml file like this:

<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>

In case you're using MySQL. Here is a list of the most common hibernate dialects used.

I have deleted all these projects, so I don't know why it's looking for them

Deleted from where? Maybe double check that they aren't any remaining traces under the deploy or tmp directories of the server configuration you're using.
