Spring Hibernate (JPA) integration

[Anup Om]

Hello Everybody,

I am running a webapp on Jboss 6. I have a UserDAO class that perists User objects annotated with JPA annotations.
Everything works fine when I use

<jee:jndi-lookup id="entityManagerFactory" jndi-name="java:/MyABookFactory" />

But, when I use below, I am getting a "java.lang.IllegalArgumentException: Unknown entity: com.mypackage.User", when I am trying to save the User object using entitymanager's persist.

<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean">
<property name="persistenceUnitName" value="MyABook" />
</bean>

Can some one please point out where I am going wrong.

Here is my applicationContext.xml

persistence.xml
