I would not have using mailing list this unless I was truely frustrated. I want to implement a very simple example using HibernateOGM but I get some exceptions, which I don't know really how can to solve them.
in the main I have started with this lock of code: OgmConfiguration cfgogm=new OgmConfiguration(); cfgogm.configure(); serviceregistry=new ServiceRegistryBuilder().applySettings(cfgogm.getProperties()).buildServiceRegistry(); sessionfactory=cfgogm.buildSessionFactory(serviceregistry); I can build my code successfully but if I run it I get some exceptions: Exception in thread "main" org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.engine.transaction.spi.TransactionFactory] at org.hibernate.service.internal.AbstractServiceRegistryImpl.createService(AbstractServiceRegistryImpl.java:186) at org.hibernate.service.internal.AbstractServiceRegistryImpl.initializeService(AbstractServiceRegistryImpl.java:150) at org.hibernate.service.internal.AbstractServiceRegistryImpl.getService(AbstractServiceRegistryImpl.java:131) at org.hibernate.cfg.SettingsFactory.buildSettings(SettingsFactory.java:180) at org.hibernate.cfg.Configuration.buildSettingsInternal(Configuration.java:2283) at org.hibernate.cfg.Configuration.buildSettings(Configuration.java:2279) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1748) at hogm.hibernateogm_mongodb.App.main(App.java:33) Caused by: org.hibernate.HibernateException: Unable to instantiate specified TransactionFactory class [org.transaction.JDBCTransactionFactory] at org.hibernate.engine.transaction.internal.TransactionFactoryInitiator.initiateService(TransactionFactoryInitiator.java:80) at org.hibernate.ogm.transaction.impl.OgmTransactionFactoryInitiator.buildServiceInstance(OgmTransactionFactoryInitiator.java:61) at org.hibernate.ogm.transaction.impl.OgmTransactionFactoryInitiator.buildServiceInstance(OgmTransactionFactoryInitiator.java:41) at org.hibernate.ogm.service.impl.OptionalServiceInitiator.initiateService(OptionalServiceInitiator.java:37) at org.hibernate.service.internal.StandardServiceRegistryImpl.initiateService(StandardServiceRegistryImpl.java:69) at org.hibernate.service.internal.AbstractServiceRegistryImpl.createService(AbstractServiceRegistryImpl.java:176) ... 7 more Caused by: org.hibernate.service.classloading.spi.ClassLoadingException: Unable to load class [org.transaction.JDBCTransactionFactory] at org.hibernate.service.classloading.internal.ClassLoaderServiceImpl.classForName(ClassLoaderServiceImpl.java:141) at org.hibernate.engine.transaction.internal.TransactionFactoryInitiator.initiateService(TransactionFactoryInitiator.java:77) ... 12 more Caused by: java.lang.ClassNotFoundException: Could not load requested class : org.transaction.JDBCTransactionFactory at org.hibernate.service.classloading.internal.ClassLoaderServiceImpl$1.findClass(ClassLoaderServiceImpl.java:99) at java.lang.ClassLoader.loadClass(ClassLoader.java:423) at java.lang.ClassLoader.loadClass(ClassLoader.java:356) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:266) at org.hibernate.service.classloading.internal.ClassLoaderServiceImpl.classForName(ClassLoaderServiceImpl.java:138) ... 13 more If I do this line of code comment, I see no exceptions: sessionfactory=cfgogm.buildSessionFactory(serviceregistry); it is my *hibernate.cfg.xml:* * * * <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" " http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <property name="hibernate.o"></property> <property name="hibernate.transaction.factory_class">org.transaction.JDBCTransactionFactory</property> <property name="hibernate.current_session_context_class">thread</property> <property name="hibernate.ogm.datastore.grid_dialect">org.hibernate.ogm.dialect.mongodb.MongoDBDialect</property> <property name="hibernate.ogm.datastore.provider">mongodb</property> <property name="hibernate.ogm.mongodb.database">rcfdb</property> <property name="hibernate.ogm.mongodb.host">127.0.0.1</property> <property name="hibernate.ogm.mongodb.port">27017</property> <mapping resource="hibernate-contact.hbm.xml"/> </session-factory> </hibernate-configuration> * could you please explain me, why I get this problem and how can I solve this? _______________________________________________ hibernate-dev mailing list hibernate-dev@lists.jboss.org https://lists.jboss.org/mailman/listinfo/hibernate-dev
