scanforMappings() method in trunk/hibernate-int/src/main/org/jboss/hibernate/jmx/Hibernate.java was changed around Beta3 to handle .hbm.xml files from ClassLoader URLs (JBAS-4242). The hibernate integration tests noted in that JIRA are failing to deploy in the latest trunk as the URLs can't be determined from the classloader which is a BaseClassLoader.

URL[] urls;
ClassLoader cl = Thread.currentThread().getContextClassLoader();
if ( cl instanceof RepositoryClassLoader )

{ urls = ( ( RepositoryClassLoader ) cl ).getClasspath(); }

else if ( cl instanceof URLClassLoader )

{ urls = ( ( URLClassLoader ) cl ).getURLs(); }

else

{ throw new DeploymentException( "Unable to determine urls from classloader [" + cl + "]" ); }
