It looks like your persistence.xml is missing the root element.

Adding the <persistence> element

i.e.

<persistence xmlns="http://java.sun.com/xml/ns/persistence"; 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; 
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence persistence_1_0.xsd" 
version="1.0">

--- Your current persistence.xml contents here ---

</persistence>
