Fluent Inteface for Message Sender

I would like to create fluent API for message sender. Lets take simple example.

messageSender.newMessage()
    .withSomeField("some value")
    .withAnotherField("some value")
.publish();

I have clases messagePublisher and message. messagePublisher has method publish(message). How I can wrap this all together to achieve the fluent way as described above?

I have came up with solution where I have class 'messageSender' which contains instance of 'messagePublisher' and use it to publish message. When I call messageSender.newMessage() it will return messageBuilder but this messageBuilder needs to have reference to messageSender, so I am than able to call the publish() method. I do not like that messageBuilder has reverence to messageSender but I am not sure how to do it differently.

Thanks in advance for any help or suggestions!

You can use inner class for MessageSender:

MessageSender.java:

public class MessageSender {
  private MessagePublisher messagePublisher;
  public void setPublisher(MessagePublisher publisher) {
    this.messagePublisher = publisher;
  }
  public static void main(String[] args) {
    MessageSender messageSender = new MessageSender();
    messageSender.setPublisher(new MessagePublisher());
    messageSender.newMessage()
      .withDestination("DEST")
      .withMsg("message")
      .publish();
  }

  public MessageBuilder newMessage() {
    return new MessageBuilder();
  }

  class MessageBuilder {
    private Message message = new Message();

    public MessageBuilder withMsg(String msg) {
      message.setMsg(msg);
      return this;
    }

    public MessageBuilder withDestination(String destination) {
      message.setDestination(destination);
      return this;
    }

    public void publish() {
      messagePublisher.publish(message);
    }
  }
}

MessagePublisher.java:

public class MessagePublisher {
  public void publish(Message message) {
    System.out.println(
      String.format(
        "Message to be sent: Msg=%s, Dest=%s", 
        message.getMsg(),
        message.getDestination()
      )
    );
  }
}

Message.java:

public class Message {
  private String msg;
  private String destination;

  public void setMsg(String msg) {
    this.msg = msg;
  }

  public void setDestination(String destination) {
    this.destination = destination;
  }

  public String getMsg() {return this.msg;}
  public String getDestination() {return this.destination;}
}
