It seems that schema of "persistence.xml" has been changed with xmlns="http://java.sun.com/xml/ns/persistence".
Try with this other one "persistence.xml": <?xml version="1.0" encoding="UTF-8"?> <persistence-unit name="articles" transaction-type="JTA"> <jta-data-source>java:/DefaultDS</jta-data-source> </persistence-unit> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3916325#3916325 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3916325 ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
