Hibernate Mapping Package

I'm using Hibernate Annotations.

In all my model classes I annotate like this:

@Entity
@Table
public class SomeModelClass {
//
}

My hibernate.cfg.xml is

<hibernate-configuration>
   <session-factory>
      <!-- some properties -->

      <mapping package="com.fooPackage" />
      <mapping class="com.fooPackage.SomeModelClass" />
    </session-factory>
</hibernate-configuration>

For every class I add to the com.fooPackage I have to add a line in the hibernate.cfg.xml like this:

<mapping class="com.fooPackage.AnotherModelClass" />

Is there a way I can add new model classes but don't need to add this line to hibernate.cfg.xml?
