    Using Ejb3Configuration()

    mat Newbie

      In our application we must dynamically connect different users to different databases. According to a previous thread:
      http://www.jboss.com/index.html?module=bb&op=viewtopic&t=77371

      we can use Ejb3Configuration() to eliminate the need for Persistent.xml


      Hoping this is the right solution, I started with:

      
       Properties properties = new Properties();
       properties.put("cache.provider_class","org.hibernate.ejb.HibernatePersistence");
       properties.put("hibernate.transaction.factory_class.","org.hibernate.ejb.HibernatePersistence");
       properties.put("connection.datasource","java:/testDS");
       properties.put("hibernate.dialect","org.hibernate.dialect.SQLServerDialect");
       properties.put("hibernate.transaction.flush_before_completion","true");
       properties.put("hibernate.hbm2ddl.auto","update");
       properties.put("hibernate.show_sql","true");
      
      
       Ejb3Configuration cfg = new Ejb3Configuration();
       EntityManagerFactory emf =
       cfg.addProperties( properties )
       .createEntityManagerFactory();
      
       EntityManager em = emf.createEntityManager();
      


      But the following NoClassDefFoundError is raised:
