Can you include the code for the class this is in?  You can't do this
in client code, and in server code, you'll need to make sure your
persistence.xml file is found (my most common mistake).

Hmm.. but, without exception?

Please, make sure that your persistence.xml is in META-INF folder inside 
your war folder. JPA implementations usually cannot find the persistence 
unit if it arent inside this folder.
