Best solution for embedding EJB3 persistence

[Michelone]

Hi everybody,

I'd like to use EJB3 persistence in my standalone applications and
webapps without using an appserver.

So I'm looking at different solutions:

- glassfish implementation: I got it working with a few libraries, but I
needed to use a provider from Oracle (I'm not sure I'm doing everything
correclty )

- hibernate: I downloaded the EntityManager wrapper with annotations and
Hibernate core. Of course it works, but it needs really *too much*
libraries! I can't deliver my 50KB swing application with 30MB of libraries!

- JBoss embedded: fro their website it seems to me the best promising
solution: all-in-one, just(!) 13MB of libraries (but I must check if all
of them are mandatory ). But it's still ALPHA and from their site I
see very few people have already downloaded it.

Is anybody trying to do the same? Any better solution?

Thanks
M.
