Learning resource for Configuring Hibernate JPA 2.0 on Glassfish server

Question

Hi guys, I am trying to create a new JEE project using hibernate and JPA 2.0 on the glass fish server.Can you guys provide me some resources to configure the above so that they work seemlessly. I have tried using netbeans and generated the persistence unit by using the hibernate provider,but i end up getting this error javax.persistence.PersistenceException: [PersistenceUnit: DBAppPU] Unable to build EntityManagerFactory I am new to all this technologies so i am looking for good resource to learn also.Your help will be greatly appreciated :) Thanks!

First, install Hibernate support via the update tool (or follow the manual procedure). Second, provide a JPA 2.0 persistence.xml to use Hibernate as JPA provider:

<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd" version="2.0">
  <persistence-unit name="MyPu" transaction-type="JTA">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <!-- JNDI name of the database resource to use -->
    <jta-data-source>jdbc/__default</jta-data-source>
    <properties>
      <!-- The database dialect to use -->
      <property name="hibernate.dialect" value="org.hibernate.dialect.DerbyDialect" />
      <!-- update database tables at deployment -->
      <property name="hibernate.hbm2ddl.auto" value="update"/>
      <!-- log the generated SQL -->
      <property name="hibernate.show_sql" value="true"/>
    </properties>
  </persistence-unit>
</persistence>
