JNDI lookup name in a standalone oc4j instance

Question

Hi,
Could you please let me know how to create a JNDI lookup name for a database in a stanalone OC4j Instance?
Both OC4J and oracle 9i database are in the same server.
Thanks in advance,

Hi,
I have the oracle 9i database as well as the oc4j instance in my local machine.I am trying to deploy a J2ee Application on the OC4j instance,using eclipse IDE.I have not created any connection pool or datasource in the oc4j instance but after i build the application I see that the connection pool and datasource instance have been created in the OC4j instance.
following are the contents of the build.xml file(for the ant build tool)

Following are the contents of Oc4J home->services->jdbc resources:
Datasource:
Name jdbc/TicketLoggingSystem
Application TicketLoggingSystem
JNDI Location jdbc/TicketLoggingSystem
Connection Pool
Managed by OC4j
Test
when i click the datasource name,I see that its type is Native datasource with no related connection pool.
Whereas for the default datasource oracleDS,
Type     Managed Data Source
Connection Pool     Example Connection Pool
However on deployment a connection pool is also created along with the datasource
Name jdbc/TicketLoggingSystem_connectionPool
Application TicketLoggingSystem
ConnectionFactory class : oracle.jdbc.pool.OracleDataSource
Do we need to bind this connection pool to our datasource?If yes how is it done.And if that is not required,why is this connection pool created?Are the datasource and connection pool already bound to each other?
Also when I test either the datasource or connection pool,it says
Confirmation     
Connection to "jdbc/TicketLoggingSystem_connectionPool" established successfully
or
Connection to "jdbc/TicketLoggingSystem" established successfully.
and displays both the connection pool and datasource details together for both the tests.
In my java code,while trying to establish connection to the database what should I mention in lookup i.e,
InitialContext context = new InitialContext();
DataSource dataSource = (DataSource) context.lookup("     jdbc/TicketLoggingSystem or      jdbc/TicketLoggingSystem_connectionPool");
con = dataSource.getConnection();
Sorry if I am sounding novice.Thanks a lot in advance,
