Stuck sending Message to JMS Queue

I wrote the following code to send a text message to JMS Queue:

package com.poc.jms;

import java.util.Hashtable;

import javax.jms.*;

import javax.naming.Context;
import javax.naming.InitialContext;

import javax.naming.NamingException;

public class JMSSender {
  public JMSSender() {
    super();
  }

public static void main(String[] args) {
    JMSSender jMSSender = new JMSSender();
    
    Context cxt;
    ConnectionFactory cf;
    Destination queue;
    Connection conn = null;
    Session sess = null;
    MessageProducer prod = null;
    TextMessage txt =  null;
        
    try {
      cxt = jMSSender.getInitialContext();
      cf = (ConnectionFactory)cxt.lookup("learn.confact-generic");
      conn = cf.createConnection();
      sess = conn.createSession(false, Session.AUTO_ACKNOWLEDGE);
      queue = (Destination)cxt.lookup("learn.queue-generic");
      prod = sess.createProducer(queue);
      txt = sess.createTextMessage("This is a test message.");
      System.out.println("Sending Message.");
      prod.send(txt);
      prod.send(sess.createMessage()); //Control message; marks end of message
      System.out.println("Message Sent.");
    } catch (NamingException e){
        e.printStackTrace();
    } catch (JMSException e) {
        e.printStackTrace();
    } catch(Exception e){
        e.printStackTrace();
    }
  }
  
  private Context getInitialContext() throws NamingException {
    Hashtable env = null;
    
    env.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
    env.put(Context.PROVIDER_URL, "t3://localhost:7001");
    
    return new InitialContext(env);
  }
}

I got the following error:

I'm using Jdeveloper 11g and Weblogic 10.3.4. Could some one please point out my mistake(s)?

Look at line 50: you assign null to the "env" variable. Then in line 52 (where the error occurred) you tried to call a method on that variable. You can't call a method of a null value.

The fix is to assign something other than null to "env" in line 50.

Jesus, I deserve to be shot! Thanks a lot man, for pointing out what kind of prize numbskull i am.

Should I mark this as "solved", then?

Yes, please. Sorry for wasting everybody's time like this, I'm so embarrassed.

Sometimes the "second pair of eyes" is helpful. Stick around here and maybe you can provide a similar service to some other unfortunate.
