Here's the code I'm using -- it's about as basic as it gets
public static void main(String[] args) {
EntityManager em = null;
EntityManagerFactory factory = null;
try
{
factory = Persistence.
createEntityManagerFactory("event",
System.getProperties());
// Create a new EntityManager from the EntityManagerFactory. The
// EntityManager is the main object in the persistence API, and is
// used to create, delete, and query objects, as well as access
// the current transaction
em = factory.createEntityManager();
Here's the standard error output I am getting (including the SAXParser type
SAXParser class --> gnu.xml.aelfred2.JAXPFactory
An error occurred while attempting to determine the version of
"file:/C:/workspaces/new-cmc/thead-new/bin/META-INF/persistence.xml".
