Posting message to weblogic JMS

Use following code snippet to post message to Weblogic JMS:

import java.util.Hashtable;
import javax.jms.*;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

public class MsgProducer {
  public MsgProducer() {

  public static void main(String[] args) {
    MsgProducer msgProducer = new MsgProducer();
    String str = "Testing JMS connectivity. Posting sample JMS message";
    Context ctx;
    ConnectionFactory cf;
    Destination queue;
    Connection conn = null;
    Session session = null;
    MessageProducer msgProd = null;
    TextMessage msg =  null;
    try {
      ctx = msgProducer.getInitialContext();
      cf = (ConnectionFactory)ctx.lookup("<Connection Factory JNDI Name>");
      conn = cf.createConnection();
      session = conn.createSession(false, Session.AUTO_ACKNOWLEDGE);
      queue = (Destination)ctx.lookup("<JMS Queue JNDI Name>");
      msgProd = session.createProducer(queue);
      msg = session.createTextMessage(str);

    } catch (NamingException e){
    } catch (JMSException e) {
    } catch(Exception e){
  private Context getInitialContext() throws NamingException {
    Hashtable env = new Hashtable();
    env.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
    env.put(Context.PROVIDER_URL, "t3://serverhost:port(8001)");
    return new InitialContext(env);
