<session-factory>  <property name="hibernate.dialect">   org.hibernate.dialect.mysql5innodbdialect  </property>  <property name="hibernate.connection.driver_class">   com.mysql.jdbc.driver  </property>  <property name="hibernate.connection.url">   jdbc:mysql://{dbinstancename}.us-west-2.rds.amazonaws.com:3306/{dbname}  </property>  <property name="hibernate.connection.username">   {username}  </property>  <property name="hibernate.connection.password">   {password}  </property> </session-factory>
