Thanks Jeff, I was able to get a stand alone Tomcat working. But for a speedy development embedded server make so much sense. Further, our team is used to running Tomcat/Jetty inline (via Maven). For some reason that configuration is not able to load the UserTransaction. Will try to switch off JTA but I am afraid when we actually deploy, we might have some unforeseen issues.
