Eclipse seems to set up persistence.xml with:- xmlns="http://xmlns.jcp.org/xml/ns/persistence";
while Tomee2.0 snapshot seems to want:- xmlns="http://java.sun.com/xml/ns/persistence"; I have Eclipse Luna installed and as up to date as is available, and JPA is set to use JPA 2.1 which seems to be the latest generic version it knows about, the alternative being EclipseLink 2.5. I take it that I have configured Eclipse wrongly somewhere, anyone got any idea where? David
