Check out this persistence.xml configuration file on my high-performance-java-persistence GitHub repository:

Code:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0"
             xmlns="http://java.sun.com/xml/ns/persistence"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
    <persistence-unit name="persistenceUnit" transaction-type="JTA">

        <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>

        <exclude-unlisted-classes>false</exclude-unlisted-classes>

        <properties>
            <property name="hibernate.archive.autodetection"
                      value="class, hbm"/>

            <property name="hibernate.transaction.jta.platform"
                      value="org.hibernate.service.jta.platform.internal.BitronixJtaPlatform"/>

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

            <property name="hibernate.hbm2ddl.auto" value="update"/>

            <property name="hibernate.connection.release_mode" value="after_transaction"/>
        </properties>
    </persistence-unit>
</persistence>


There are two very important settings here:

1. exclude-unlisted-classes - which instructs Hibernate not to exclude classes that were not listed in the persistence.xml file.
2. hibernate.archive.autodetection - which instructs Hibernate to scan both classes for annotations and HBM files.
