Hi Now I remenber I had to pass a blank persistence.xml file so that the enhancer would work. See my previous post for the ant target, and below for the dummy persistence file.
<?xml version="1.0"?> <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 http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"; version="1.0"> <persistence-unit name="none"/> </persistence> This method has been working great for me.
