I am getting the following error while trying out this JPA tutorial:

Here is my persistence.xml:

Person.java

(getters and setters)
Part of my JUnit Test file:
@SuppressWarnings("unchecked")
@Test
public void insertAndRetrieve() {
em.getTransaction().begin();
em.persist(p1);
em.persist(p2);
em.getTransaction().commit();
final List<Person> list = em.createQuery("select p from Person p")
.getResultList();
System.out.println("here...");
assertEquals(2, list.size());
I am using MySQL db, the ‘person’ table is present in the database. And after
em.getTransaction().begin();
em.persist(p1);
em.persist(p2);
em.getTransaction().commit();
I can see the two records are inserted in the person table. But on the next statement, it fails.
EDIT 1:
JARs in my build path:
antlr-2.7.6.jar,
commons-collections-3.1.jar,
dom4j-1.6.1.jar, hibernate3.jar,
hibernate-annotations-3.5.5-Final.jar,
hibernate-commons-annotations-3.2.0.Final.jar,
hibernate-entitymanager-3.5.5-Final.jar,

slf4j-api-1.6.1.jar,
slf4j-simple-1.6.1.jar,
hibernate-jpa-2.0-api-1.0.0-CR-1.jar
Can anyone tell me what I am doing wrong?
Thanks.
Remove the ejb3-persistence.jar JAR file from the class path. It contains the interfaces of the JPA 1.0 specification. You’ll need to retain the hibernate-jpa-2.0-api-1.0.0-CR-1.jar JAR file, for it contains the interfaces for the JPA 2.0 specification.
Note: If you need to work against JPA 1.0, then do not use Hibernate 3.5.5 for it contains the JPA 2.0 implementation. In the future, use Maven for dependency management; it will help you avoid these issues.
Addendum:
If I were to setup Hibernate EntityManager 3.5.5 (JPA 2) from scratch, these would be the files I would consider. The following list has been inferred from the Hibernate documentation :
The last two haven’t been mentioned in the documentation, but are required. I don’t see the need for any of the other JARs, except for mysql-connector-java-5.1.15.jar and log4j-1.2.12.jar (both of which could be retained).
