/**
 * Used by {@link AbstractOpenEJBDbUnitTest}, but can be used directly from application
 * project (<code>test.ejb-jar</code> file) also. The 'openejb.deployments.classpath.include'
 * will cause this EJB to be automatically discovered and deployed when OpenEJB
 * boots up. When using multiple persistence units you have to skip auto deploy
 * by adding the following property to <code>openejb-test.properties</code>:
 * <pre>
 * openejb.deployments.classpath.include=
 * </pre>
 * <p>
 * Instead you should deploy it via <code>test.ejb-jar</code> file and define the persistence
 * unit to use.
