Can't create a service for failover on 2 node windows2008 RAC

Question

To create a new service for failover,
1)Enterprise Manager can not be used by prompting an error: many people already mentioned.
2)Net Manager could create a service but it fails to test showing:
Attempting to connect using userid: qa1
The test did not succeed.
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
Q1: According to doc, it should be used ONLY for Non-cluster and single instance. Is this why I have an error?
Q2: If not, what should I need to do to fix this problem?
3)Using command line like
C:\Users\administrator.QAPF2>srvctl add service -d ORCL -s NLS -r orcl1 -a orcl2
C:\Users\administrator.QAPF2>srvctl start service -d ORCL -s NLS
C:\Users\administrator.QAPF2>srvctl status service -d ORCL -s NLS
Service NLS is running on instance(s) orcl1
C:\Users\administrator.QAPF2>sqlplus /nolog
SQL> connect sys as sysdba
SQL> alter system register;
When I try to connect from client using "jdbc:oracle:thin:@orarac-scan:1521:NLS" connection string, I got the following error:
Listener refused the connection with the following error:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptor
The Connection descriptor used by the client was:orarac-scan:1521:NLS
Note: If I use "ORCL1" instead of NLS, then it works. ORCL1=SID on node1, NLS=service name.
Q3: Are there anything I should do more?
Q4: How do I add a listener for this new service(NLS)? I added the following using Net Manager but no effect:
(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = orarac-scan)(PORT = 1521)))

Yes, it worked with sqlplus commandline(local or from remote) like:
C:\>sqlplus system@NLS

From a remote client:
C:\oracle>sqlplus qa1@NLS

However, if I use the connection string suggested by you:
C:\oracle>sqlplus qa1@\"orarac-scan:1521/NLS\"
SQL*Plus: Release 11.1.0.6.0 - Production on Tue Apr 24 10:14:30 2012
