Spring3 +JPA

1)META-INF/persistence.xml

This EntityManagerFactory bootstrap is appropriate for standalone applications

 * which solely use JPA for data access. If you want to set up your persistence

 * provider for an external DataSource and/or for global transactions which span

 * multiple resources, you will need to either deploy it into a full Java EE 5

 * application server and access the deployed EntityManagerFactory via JNDI,

 * or use Spring's {@link LocalContainerEntityManagerFactoryBean} with appropriate

 * configuration for local setup according to JPA's container contract.
