configure hibernate using oracle rac

The ordinary way to configure hibernate link oracle database is just like this:

jdbc:oracle:thin:@192.100.99.103:1521:Orcl

But some times the database server using double network-cards or using rac. Then the configure will be:

jdbc:oracle:thin:@
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.100.99.103)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.100.99.104)(PORT = 1521))
(LOAD_BALANCE = yes)
)
(CONNECT_DATA =
(SERVICE_NAME = Orcl)
)
)

The segment of connection url is copied from oracle configuration file(usually under Oracle_Home\app\product\11.2.0\dbhome_1\NETWORK\ADMIN\tnsnames.ora).
