We will create an object and then some more classes to persist (save/retrieve/delete) that object from the database. In Java speak, we call the object a Plain Old Java Object (a.k.a. a [POJO|http://forum.java.sun.com/thread.jsp?forum=92&thread=425300&tstart=0&trange=15]). This object basically represents a database table. The ''other classes'' will be:

At this point, the PersonDaoTest class won't compile yet because there is no PersonDao.class in our classpath, we need to create it. PersonDAO.java is an interface, and PersonDAOHibernate.java is the Hibernate implementation of that interface. Let's go ahead and create those.

Let's start by creating a PersonDaoHibernate class that implements the methods in PersonDao and uses Hibernate to get/save/delete the Person object. To do this, create a new class in src/dao/**/dao/hibernate and name it PersonDAOHibernate.java. It should extend [BaseDaoHibernate|http://raibledesigns.com/downloads/appfuse/api/org/appfuse/dao/BaseDAOHibernate.java.html] and implement PersonDAO. ''Javadocs eliminated for brevity.''

Now, if you try to run "ant test-dao -Dtestcase=PersonDao", you will get the same error. We need to configure Spring so it knows that PersonDaoHibernate is the implementation of PersonDAO, and we also need to tell it about the Person object.
