sounds like wrong db or persistence not being loaded.
 
If using Studio to generate project click edit in initial wizard and go to driver properties and make sure those are in fact your db. Make sure when deploying app that you see it found in the hibernate log.
 
If using JBoss 5 make sure you are retrieving your entityManagerFactory from JNDI.
 
persistence.xml

         <property name="jboss.entity.manager.factory.jndi.name" value="java:/myEntityManagerFactory"/>
 
components.xml
     <transaction:entity-transaction entity-manager="#{em}"/>
                  
    <persistence:entity-manager-factory name="myDatabase" installed="@loadPersistenceUnits@"/>

    <persistence:managed-persistence-context name="em" auto-create="true"
       entity-manager-factory="#{myDatabase}" persistence-unit-jndi-name="java:/myEntityManagerFactory"/>
