if (cl instanceof ReportClassLoader)
{
List items = ((ReportClassLoader)cl).getCachedItems();
java.net.URL[] urls = new java.net.URL[items.size()];
for (int i=0; i<items.size(); ++i)
{
urls[i] = new java.io.File(""+items.get(i)).toURL();
}
URLClassLoader urlClassLoader = new URLClassLoader(urls, cl );
Thread.currentThread().setContextClassLoader(urlClassLoader );
}
// System.out.println(Misc.nvl(getProperties().get("PersistenceUnit"), null));
emf = Persistence.createEntityManagerFactory(
Misc.nvl(getProperties().get("PersistenceUnit"), null), new HashMap());
//if (emf == null) throw new Exception("Unable to create the EntityManagerFactory for persistence unit " + Misc.nvl(getProperties().get("PersistenceUnit"), null));
//Thread.currentThread().setContextClassLoader().
