Hibernate 可编程配问题?100分

                        Configuration   cfg   =   new   Configuration()
                        .addFile( "CcCifNgtvInfo.hbm.xml ");
                        SessionFactory   sessions   =   cfg.buildSessionFactory();//到这里抛出异常
                        Session   sess   =   sessions.openSession(conn);//程序已有的连接

------解决方案--------------------
Hibernate Dialect must be explicitly set
就是说你hibernate方言没设正确 检查你的hibernate.cfg.xml
<?xml version= "1.0 " encoding= "utf-8 "?>
<!DOCTYPE hibernate-configuration
PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN "
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd ">

<hibernate-configuration>
<session-factory>
<!-- datasource connection properties -->
<property name= "connection.datasource ">
java:comp/env/jdbc/arts
</property>
