there should be "Caused by:" part of this stacktrace -- can you share that
too?

class to the entities package, right?
Right, but you don't even have to put your entities to the "entities"
package provided that you specify your persisted classes in your
persistence.xml. Which you actually did, but you also have this line in
there:
<exclude-unlisted-classes>**false</exclude-unlisted-**classes>
which is not necessary if you specified full list of persisted classes
there. I'd say more, that having this exclude-unlisted-**classes=false may
increase start-up time for your application significantly.
