Problem with Hibernate Shards & JNDI

I'm trying to run a sample program for hibernate shards. I'm all done with it but whenever I run the test program I get an Exception

javax.naming.NoInitialContextException: Need to specify class name in environment or system property

After googling I got to know that I've to set the JNDI properties. I did like this

Hashtable env = new Hashtable();
env.put( Context.INITIAL_CONTEXT_FACTORY,"com.sun.enterprise.naming.SerialInitContextFactory");
env.put( Context.PROVIDER_URL, "<some-IP>:3306" );
Context initialContext = new InitialContext(env);

But still things are not working.:-( Please help. What n where I'm missing?

Here is the code :

public class SessionFactoryImpl {

    private static final String SHARD_CFG_0 = "/com/hibshards/config/shard0.hibernate.cfg.xml";
    private static final String SHARD_CFG_1 = "/com/hibshards/config/shard1.hibernate.cfg.xml";
    private static final String SHARDED_TABLE = "com/hibshards/orm/weather.hbm.xml";

    public static SessionFactory createSessionFactory() throws NamingException {
        Configuration prototypeConfig = new Configuration().configure( SHARD_CFG_0 );
        prototypeConfig.addResource( SHARDED_TABLE );

        List<ShardConfiguration> shardConfigs = new ArrayList<ShardConfiguration>();
        shardConfigs.add( buildShardConfig( SHARD_CFG_0 ) );
        shardConfigs.add( buildShardConfig( SHARD_CFG_1 ) );

        ShardStrategyFactory shardStrategyFactory = buildShardStrategyFactory();
        ShardedConfiguration shardedConfig = new ShardedConfiguration(
                prototypeConfig,
                shardConfigs,
                shardStrategyFactory);
        return shardedConfig.buildShardedSessionFactory();
    }

    private static ShardStrategyFactory buildShardStrategyFactory() {

        ShardStrategyFactory shardStrategyFactory = new ShardStrategyFactory() {
            public ShardStrategy newShardStrategy(List<ShardId> shardIds) {
                RoundRobinShardLoadBalancer loadBalancer = new RoundRobinShardLoadBalancer( shardIds );
                ShardSelectionStrategy pss = new RoundRobinShardSelectionStrategy( loadBalancer );
                ShardResolutionStrategy prs = new AllShardsShardResolutionStrategy( shardIds );
                ShardAccessStrategy pas = new SequentialShardAccessStrategy();
                return new ShardStrategyImpl( pss, prs, pas );
            }
        };
        return shardStrategyFactory;
    }

    private static ShardConfiguration buildShardConfig( String configFile ) {
        Configuration config = new Configuration().configure( configFile );
        return new ConfigurationToShardConfigurationAdapter( config );
    }
}

In a simple java application, you don't need a name for the session factory..try removing the name in your cfg.xml file and executing it
