You need to configure a persistence.xml file and then pack it in the META-INF dir of the ejb jar.  The persistence.xml will look somethjing like so:

<?xml version="1.0" encoding="UTF-8"?>
  | <persistence>
  |         <persistence-unit name="myPU">
  |                 <jta-data-source>java:/<you firebird ds name></jta-data-source>               
  |                 <class><managed class name></class>
  |                 <properties>
  |                         <property name="hibernate.dialect" value="org.hibernate.dialect.FirebirdDialect"/>
  |                         <property name="hibernate.hbm2ddl.auto" value="create-drop"/>                                           
  |                 </properties>
  |         </persistence-unit>
  | </persistence>

You can then inject an EntityManager with the @PersistenceContext annotation within a Session bean.
