First, java is not a plus IMHO. Any time I have used anything java based, it's been quite slow. You also have to deal with all the typical java issues like memory and heap space, but that is another diacussion all together. NoSQL is just that, no SQL. If you want an SQL database, use one. The creators of the nosql db's did so for a reason, I don't see the need to back port it in. Sorry for the rant.
