Hi Brian, <br><br>The method <br><a href="http://java.sun.com/javaee/5/docs/api/javax/persistence/Persistence.html#createEntityManagerFactory(java.lang.String,%20java.util.Map)" target="_top" rel="nofollow">createEntityManagerFactory(String persistenceUnitName, Map properties)</a><br><br>takes a Map as the second argument, rather than a URL. <br><br><blockquote class="quote light-black dark-border-color"><div class="quote light-border-color"> <div class="quote-author" style="font-weight: bold;">Brian H1 wrote:</div> <div class="quote-message shrinkable-quote">Hi, <br><br>I'm wondering if I could get some clarification on this method from someone who's used this? I always seem to get a null back. If I make call this method <br>URL xxx = getClass().getResource("/META-INF/persistence.xml");, I get a valid url that has a fully qualified path to the persistence.xml. But, I haven't been able to turn around and use that path as the resource in the createEntityManagerFactory method. Is the string "resource" parameter meant to be a file path?
