how to get connection from dedicated server?

the tnssetting looks below.

MYDB =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP) (HOST = 10.23.10.62) (PORT = 1521))
(ADDRESS = (PROTOCOL = TCP) (HOST = 10.23.10.61) (PORT = 1521))
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = MYSID)
(FAILOVER_MODE =
(TYPE = SELECT)
(METHOD = BASIC)
(RETRIES = 180)
(DELAY = 2)
)
)
)

in my java file
String url = "jdbc:oracle:thin:@10.23.10.62:1521:MYSID";
String user = "user";
String password = "passwd";
con = DriverManager.getConnection(url, user, password);

give the SQLException below.

java.sql.SQLException: IO Exception: Connection refused(DESCRIPTION=(TMP=)(VSNNUM=169870080)(ERR=12505)(ERROR_STACK=(ERROR=(CODE=12505)(EMFI=4))))

ORA-12505: TNS:listener does not currently know of SID given in connect descriptor
 *Cause:  The listener received a request to establish a connection to a
 database or other service. The connect descriptor received by the listener
 specified a SID for an instance (usually a database instance) that either
 has not yet dynamically registered with the listener or has not been
 statically configured for the listener. This may be a temporary condition
 such as after the listener has started, but before the database instance
 has registered with the listener.
 *Action:
  - Wait a moment and try to connect a second time.
  - Check which instances are currently known by the listener by executing:
    lsnrctl services <listener name>
  - Check that the SID parameter in the connect descriptor specifies
    an instance known by the listener.
  - Check for an event in the listener.log file.

I haven't checked your suggestions.
let me check at the office tomorrow ^^.

btw, this could happen depending on the oracle jdbc driver versions?

Looks like Oracle RAC.

Use url string like the below.

String url = "jdbc:oracle:thin:@(description=(address_list= (address=(host=172.18.137.231) (protocol=tcp)(port=1521))(address=(host=172.18.137.230)(protocol=tcp) (port=1521)) (load_balance=yes)(failover=yes))(connect_data=(service_name= slrac.bea.com)))";
