Hi
I tried Glassfish 3.1.1 and configured resources and everything and got it
working. My application was happily connecting to database but the same
problem has started acting up again. I again have started getting
*java.lang.IllegalStateException: Unable to retrieve EntityManagerFactory for
unitName null* error. [jpa] engine is not listed with [web, ejb] and my
application can't connect to database anymore.
Could someone help me solve this problem?
Thanks.
