      <properties>
          <property name="hibernate.dialect" value="org.hibernate.dialect.DB2Dialect" />
          <property name="hibernate.connection.driver_class" value="com.ibm.db2.jcc.DB2Driver" />
          <property name="hibernate.connection.password" value="world" />
          <property name="hibernate.connection.url" value="jdbc:db2://localhost:50000/hello" />
          <property name="hibernate.connection.username" value="db2admin" />
          <property name="hibernate.ejb.autodetection" value="none" />
          <property name="hibernate.max_fetch_depth" value="3"/>          
    </properties>
   </persistence-unit>
</persistence>

my question is if I delete the class list,It also could find all of classes with '@Entity' annotation, even there is no class in the list.
Is it right?
If I have two or more EntityManager in my application.How it could work good for each other?

You also need to remove the hibernate.ejb.autodetection overriding to make it work.

The idea behind autodetection is to put the entities of a given Persistence Unit in the same jar and add the persistence.xml in it. So having 2 PUs usually means having 2 jars.
