No qualifying bean of type 'javax.persistence.EntityManagerFactory' available for OSGi Application

Question

I am working on a Maven OSGi bundle that incorporates JPA (through EclipseLink ) and when I deploy the bundle into the OSGi container (Virgo), I receive the following error:

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'javax.persistence.EntityManagerFactory' available

The class in question that causes the error is:

@Configurable
@Entity
@Table(name = "SCHEDULE")
@RooJavaBean
@RooToString
@RooJpaActiveRecord(versionField = "", table = "SCHEDULE")
@RooDbManaged(automaticallyDelete = true)
public class Schedule {

    @PersistenceContext
    transient EntityManager entityManager;

    ...
}

Both the persistence.xml and orm.xml files have been placed in the src/main/resource/META-INF directory. The contents of the persistence.xml file is as follows:

Lastly, there is a database.properties file in src/main/resource/META-INF/spring/ that contains the following:

database.driverClassName=com.mysql.jdbc.Driver
database.url=jdbc\:mysql\://localhost\:3306/<hidden>
database.username=<hidden>
database.password=<hidden>

Am I making a configuration or wiring mistake somewhere that is causing the EntityManagerFactory not to be created or wired correctly upon deployment?

Thank you for the help.

Aside

I have also attempted to follow A Guide to Hibernate with Spring 4 and include the following in the definition of org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean :

<bean id="myEmf" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    ...
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
    </property>
</bean>

I follow through and added all of the OSGi bundles that go along with the HibernateJpaVendorAdapter class (eg hibernate-core, hibernate-osgi, etc.) and that led back to the same error as above.

Answer 1

I'm hazarding a guess at this but you have two persistence units defined, name="PGSQLPersistence" and name="PGSQLTESTPersistence" .

I think you need to specify which PU you want to use in your @PersistenceContext annotation, eg @PersistenceContext(unitName = "PGSQLPersistence") although I would have expected a slightly different exception thrown as a single PU cannot be automatically determined.

Answer 2

尝试按照Kerry的建议通过名称更改@PersistenceContext上的unitName属性

Answer 3

The solution I found was to circumvent the JPA portion of the bundle I was creating and directly create a HibernatePersistenceProvider :

EntityManagerFactory factory = new HibernatePersistenceProvider().createEntityManagerFactory("persistenceUnitName", null);

This does not solve the issue itself but removes the issue of resolution entirely. My suspicion is that OSGi and JPA are not being configured correctly in our environment and therefore, OSGi cannot find any EntityManagerFactory instances to inject.
