I try to programmatically configure hibernate 3.2 in MBean:

String mappings = " <?xml version=\"1.0\"?><hibernate-mapping></hibernate-mapping>";
new Configuration()
.addXML(mappings)
.setProperty("hibernate.session_factory_name", "hibernate/Test")
.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQL5Dialect")
.setProperty("hibernate.connection.datasource", "java:/database")
.setProperty("hbm2ddl.auto", "update")
.setProperty("current_session_context_class", "thread").buildSessionFactory();

and recieve this exception:

If I place xerces-3.2.6.jar from hibernate distribution, configuration will succeed, but jboss will not deploy any jar because it will be unable to parse descriptor
