I am assuming this to be a typo. You probably wanted to write
EntityManager instead of EntityManagerFactory. If not, then you must fix
your code.

I don't understand why you need al the above entries in ejb-jar.xml when
you are already using annotations. You should reconsider use of ejb-jar.xml.

The error indicates that the ejb module is not able to see the
persistence units. If you run "glassfish_home/bin/verifier <your ear
file>," you will get a better diagnostic message. The problem seems to
be that you have packaged your persistence units in some other ejb-jar
and you are trying to use them from another ejb-jar. As per the
visibility rules of persistence units, when a persistence unit is
packaged in a component jar like ejb-jar, it is considered private to
that jar. To fix your issue, you need to package your persistence units
in a library jar. Check out [1].
