[hibernate-dev] Hbm mapping with hibernate 4

Hey, guys, I created the simplest hbm mapping and try to build session factory(full project attached, Hibernate-core4.0.0.CR6): /new MetadataSources( new ServiceRegistryBuilder().configure() .buildServiceRegistry()).buildMetadata().buildSessionFactory();/ And I get this exception(full log attached): Caused by: org.xml.sax.SAXParseException; lineNumber: 5; columnNumber: 26; cvc-elt.1: Cannot find the declaration of element 'hibernate-configuration'. at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.createSAXParseException(ErrorHandlerWrapper.java:198) ... When I build session factory using old syntax /new Configuration().configure().buildSessionFactory();/ it works only with DTD schema(not 100% sure I found a correct header to use xsd for hibernate.cfg.xml): <hibernate-configuration xmlns="http://www.hibernate.org/xsd/hibernate-configuration" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.hibernate.org/xsd/hibernate-configura... https://raw.github.com/hibernate/hibernate-core/master/hibernate-core/src... . This seems like a bug, or I do something wrong? Dmitry Geraskov
