Unable to Initialize InitialContext in JBoss AS 7.1 - jboss7.x

Question

I am unable to initialize InitialContext and lookup for a string. Here is my code snippet :
java.util.Hashtable env = new java.util.Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,"org.jboss.naming.remote.client.InitialContextFactory");
env.put("java.naming.provider.url","remote://localhost:4447");
env.put("java.naming.factory.url.pkgs","org.jboss.naming:org.jnp.interfaces");
try
{
if(env != null)
ic = new InitialContext(env);
else
ic = new InitialContext();
this.connectionFactory = (ConnectionFactory)ic.lookup("java:/ConnectionFactory");
this.queue = (javax.jms.Queue)ic.lookup("java:jboss/exported/jms/queue/test");
}catch(Exception e){
e.printStackTrace();
}
Always ic is being null and I am getting Exception NullPointer Exception.
Can anyone tell me where the wrong I have done or any configuration? Any suggestion/advice are acceptable.

It looks like you don't have the InitialContextFactory class on your classpath. The jar you need will be in the bin/client directory of your JBoss installation. See this link for details : https://docs.jboss.org/author/display/AS72/JNDI+Reference
