Websphere JMS queue connection issue - ConfigURL property file is not set - websphere

Question

Facing the below exception when try to push msg into jms queue in Wrbsphere server.
Please let me know if any help can get on this.
Exception:
JSAS1480I: **Security is not enabled because the ConfigURL property file is not set.**
javax.naming.NamingException: Error getting WsnNameService properties [Root exception is org.omg.CORBA.TRANSIENT: initial and forwarded IOR inaccessible vmcid: 0x4942f000 minor code: 3591 completed: No]
My code:
private void putmsg() throws NamingException, JMSException, IOException {
Context namingContext = null;
final Properties prop = new Properties();
prop.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory");
prop.put(Context.PROVIDER_URL, "iiop://localhost:2809");
prop.put(Context.SECURITY_PRINCIPAL, "admin");
prop.put(Context.SECURITY_CREDENTIALS, "admin");
prop.put("connection.factory", "jms/t24ConnectionFactory");
namingContext = new InitialContext(prop);
ConnectionFactory connectionFactory =
(ConnectionFactory) namingContext.lookup("jms/t24ConnectionFactory");
Destination queue = (Destination) namingContext.lookup("jms/t24OFSQueue");
Connection connection = connectionFactory.createConnection();
Session session = connection.createSession();
String input = FileUtils.readFileToString(new File("C:\\inflow\\ResponseOut1.xml"));
MessageProducer producer = session.createProducer(queue);
TextMessage txtMsg = session.createTextMessage(input);
((MessageProducer) producer).send(txtMsg);
connection.close();
}
I think i have missing some configuration related to websphere.
