You need to implement your own NamingStrategy (org.hibernate.cfg.NamingStrategy). Maybe subclassing the one you are currently using is the easiest way (by default hibernate is using the DefaultNamingStrategy).

Then configure the sessionFactory with your naming strategy:

SessionFactory sf = new Configuration()
    .setNamingStrategy(new YourNamingStrategy())
    .addFile(...)
    .buildSessionFactory();

Or via spring dependency injection on the session factory, if you are using it :

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
...
  <property name="namingStrategy">
    <ref bean="namingStrategy" />
  </property>
...
