Create Consumer Project

Create Java Project in Eclipse. Right click the project select Build Path\Configure Build Path menu. In Libraries tab, select all jar files above to the project. Besides, we need add appserv-rt library in glassfish4\glassfish\lib folder from GlassFish Server as photo below:

Consumer Project Structure

Create Message Listener class

This class contains methods to receive file from destination

package demo.spring_jms;

import java.io.FileOutputStream;

import javax.jms.BytesMessage;
import javax.jms.Message;
import javax.jms.MessageListener;

public class FileMessageListener implements MessageListener {

	@Override
	public void onMessage(Message message) {
		try {
			if (message instanceof BytesMessage) {
				BytesMessage bytesMessage = (BytesMessage) message;
				int TEXT_LENGTH = new Long(bytesMessage.getBodyLength()).intValue();
				byte[] textBytes = new byte[TEXT_LENGTH];
				bytesMessage.readBytes(textBytes, TEXT_LENGTH);

				// Save file
				FileOutputStream fos = new FileOutputStream("src\\data\\b.txt");
				fos.write(textBytes);
				fos.close();

				// Show content of file
				String content = new String(textBytes);
				System.out.println(content);
			}
		} catch (Exception e) {
			System.err.println(e.getMessage());
		}
	}

}

Spring JMS Configuration File

The Spring configuration shows a context:component-scan that picks up the JMS listener.

Run Application

package demo.spring_jms;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Main {

	public static void main(String[] args) {

		try {
			ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
		} catch (Exception e) {
			System.err.println(e.getMessage());
		}

	}

}

Output

Hello World
