Hi David, I have settled this problem with your suggestion plus some reference to old msg in this mailing list
I do not sure which steps that I took that solve this problem but I follow all the below steps still does not work , I finally try a few other steps and at the end , adding <non-jta-data-source> tag in persistence.xml solve my problem. Thanks for your help.
