Guice JPA + HIbernate

[Ronak Patel]

HI,

How do I use Guiceyfruit's JPA support with Hibernate??

I can't seem to find anything written about it on your website....

Thanks!!

So, all I ever get is:

When I have the following Guice Module:

public class ServiceModule extends AbstractModule {

private static final Logger logger = Logger.getLogger
(ServiceModule.class);

/* (non-Javadoc)
* @see com.google.inject.AbstractModule#configure()
*/
@Override
protected void configure() {

ServiceModule.logger.info("AFE Service: Configure Start
Initialization Commencing...");
final long now = System.currentTimeMillis();

//Install the JPA and JSR-250 modules
this.install(new JpaModule());

//Install Hibernate as the JPA Provider
this.bind(PersistenceProvider.class).to(HibernatePersistence.class);
}
}

How do I use Guiceyfruit with JPA here?? If I don't get an answer...I
will have to switch to Spring Framework to get this to work
correctly....

I think you need to register a EntityManager instead?

I've hacked the test case for JPA to show how you could register an
EntityManagerFactory instance object; then a provider method to use it
to create the EntityManager objects (the method annotated with
@Provides).

http://code.google.com/p/guiceyfruit/source/browse/trunk/guiceyfruit-jpa/src/test/java/org/guiceyfruit/jpa/InjectionTest.java

Does that help? The only change from the JpaModule used in this test
case should be a different instance of the EntityManagerFactory

James,

When I try to register Hibernate using Hibernate EntityManager's
EntityManagerImpl.class, Guiceyfruit complains that EntityManagerImpl
does not have a default constructor...which it does not....

What do I do then? I don't control Hibernate nor want to....(I've
spent many hours frustrated with this...as I'm sure you can tell....)
