 Post subject: No Dialect mapping for JDBC type -4 image longblob byte[]

I have one problem, I do this:

imagen=(byte[]) entityManager.createNativeQuery(select image from images where imageid=43).getSingleResult();

And I get this exception:

No Dialect mapping for JDBC type -4

I'm running Mysql, with driver 5.0.8, the field's type is longblob, do I have to do something different to retrieve the image?
