J2SE and binding Datasource to JNDI

Question

Hi all,
I am trying to create a ODBC-Bridge datasource as per :http://java.sun.com/j2se/1.5.0/docs/guide/jdbc/bridge.html
I get the initailContect not defined with the following code
InitialContext ic = new InitialContext();
ic.bind("jdbc/OdbcDB1",ds);
so tried adding this :
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://localhost:389/o=JNDITutorial");
Context ctx = new InitialContext(env);
This also produces an error as LDAP not running i guess??
I do not understand the initial context, and am not sure the type i should use (LDAP / DNS / CORBA) etc.
I guess when running a web or J2EE the JNDI is already running and the initial contect is already setup?

Here is the whole piece of code. I need the program to be a standalone Java program. wlclient.jar is in the classpath.
It works when binding strings and looking up existing objects registered to JNDI.
import java.util.Properties;
import javax.naming.Context;
import javax.naming.InitialContext;
import com.mockrunner.mock.jdbc.JDBCMockObjectFactory;
import com.mockrunner.mock.jdbc.MockDataSource;
JDBCMockObjectFactory factory = getJDBCMockObjectFactory();
MockDataSource ds = factory.getMockDataSource();
Properties env = new Properties();
env.put( Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory" );
env.put( Context.PROVIDER_URL, "t3://localhost:7001" );
InitialContext context = new InitialContext(env);
context.rebind("MockDataSource", ds);
