Answer 1

Ok, I Solved this..

What i did is to put the persistence.xml file within the META-INF folder as vikdor and axtavt suggested. but in the application context i didn't import any file.. just wrote this

<bean id="JPA" class="pack.jpa.JPAQueries"/>

and its work!

Answer 2

It should be imported as follows:

<import resource="classpath:META-INF/persistence.xml"/>

assuming the persistence.xml is present in META-INF directory which is a top-level directory in one of your jars on the classpath.

Answer 3

Your attempt to use persistence.xml as a Spring config makes absolutely no sense, because persistence.xml is not a Spring config.

If you want to use JPA with Spring, you need to put persistence.xml into META-INF folder inside your source folder, and declare LocalContainerEntityManagerFactory in applicationContext.xml:

<bean id="emf" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name = "persistenceUnitName" value = "MyJPA" />
</bean>

Then you can inject EntityManager into your Spring bean using @PersistenceContext:

@PersistenceContext
private EntityManager em;
