Using EntityManager in Hibernate Validator

[csl]

I try to use the EntityManager in a Hibernate Validator, for I'd like to ensure the uniqueness of a username. This should get reported to the user using ajax4jsf. I implemented it using a JSF Validator and it worked, but the Hibernate Validator approach would be preferable, I guess.

How can I inject the EntityManager into my Validator? I also tried Component#getInstance but it returns a proxy to an already closed Entity Manager...

Just guessing here but can you get the EntityManagerFactory from JNDI?

Yes, this works.

Context ctx = new InitialContext();
EntityManagerFactory entityManagerFactory = (EntityManagerFactory) ctxlookup("java:/myprojectEntityManagerFactory");
entityManager = entityManagerFactory.createEntityManager();

But isn't there a better way to do this? It would be great if I could obtain Seam components (e.g. Log).

Hibernate Validators are not Seam components and don't fall within the Seam lifecycle hence you can't do injection in there.
