Red Hat JBoss Fuse - Connecting to A-MQ in EAP with Camel

JBoss EAP has a built-in Messaging solution, HornetQ. Sometimes we need A-MQ for more protocol support, reliable messaging and HA capability. By connecting through the resource adaptor in EAP, we will be able to connect EAP to A-MQ.

First install the A-MQ library into EAP.

You can find it in the A-MQ zip file, under /jboss-a-mq-6.2.x.redhat-xxx/extras/,
in there you can find a file, unzip it, there you can locate the library we need in apache-activemq-5.11.x.redhat-62xxxx/lib/optional. 

  • activemq-rar-5.11.x.redhat-62xxxx.rar

Make sure you start up both the JBoss A-MQ(with ID/PWD: admin/admin) and JBoss EAP, go to the JBoss Admin Console located at http://localhost:9990 and logon with the ID/PWD previously set by you when installing. There are several options here,
  1. Install the libraries through deployment
  2. Install as module

So I am going to do the easy way, which is deploy the libraries. This is not recommended in production (since anyone with admin right and remove, disable the library..).  In the admin console, go to Runtime/Manage Deployments, and click on "Add" button to add the rar file.

After successful deployment, enable the rar file.

And we are now ready to start setting the resource adaptor. Go to Configuration -> Under Connector, click on Resource Adapters, and it will display the configuration page. Click on Add to add our new Resource, which A-MQ.

A screen will then pop-up, enter
which is the name when you deploy the library on EAP. And select XATransaction.

Under Properties tab, enter the following settings,

  • UserName: admin
  • Password: admin
  • UseInboundSession: true
  • ServerUrl: tcp://localhost:61616?jms.rmIdFromConnectionId=true

We can now setup the ConnectionFactory for the broker, first click on view in In the Connection Definition configuration page, click on add, a popup will appear, enter following information.

  • Name: localhostConnectionFactory
  • JNDI Name: java:jboss/jms/activemq/ConnectionFactory
  • Connection Class: org.apache.activemq.ra.ActiveMQManagedConnectionFactory

Under Properties, please enter the following config. 
  • UserName: admin
  • Password: admin
  • UseInboundSession: true
  • ServerUrl: tcp://localhost:61616?jms.rmIdFromConnectionId=true
And lastly, enable the connection factory.

This is what it looks like.

Normally, that is all we need for Camel application. BUT! If you would like to map to your messaging queue or topics via Message Driven Bean, we need to go for an extra step to create the adapter for Queue and Topics as well. Here I am going to use queue as an example.

Go to Admin Objects unser Resource Adapter,

Click on Add to add an admin object, enter:

  • Name:testQueue
  • JNDI Name:java:jboss/jms/amq/queue/testQueue
  • Class Name: org.apache.activemq.command.ActiveMQQueue

In Properties tab add

  • PhysicalName:TEST.QUEUE

And enable the testQueue.
And to add resource mapping to Message driven bean, we need to map the resource adapter to our message driven bean in the container, go to standalone.xml or domain.xml (depends on if you are in standalone or domain mode). Here I am starting using standalone mode, so I will open my standalone.xml under standalone/configuration folder in JBoss EAP. 

Under ejb3 subsystem, add mdb mapping. 

<subsystem xmlns="urn:jboss:domain:ejb3:1.5">
      <resource-adapter-ref resource-adapter-name="activemq-rar-5.11.0.redhat-620133.rar"/>
      <bean-instance-pool-ref pool-name="mdb-strict-max-pool"/>

That's it for the setting. You have successfully created a Resource Adaptor from JBoss EAP to JBoss A-MQ. 

To do a little testing, I created a small MDB project, 
we can map the destination queue to "queue/testQueue" 

package com.redhat.mdb;

import java.util.logging.Logger;

import javax.ejb.ActivationConfigProperty;
import javax.ejb.MessageDriven;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.TextMessage;

@MessageDriven(name = "TestMDB", activationConfig = {
@ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"),
@ActivationConfigProperty(propertyName = "destination", propertyValue = "queue/testQueue"),
@ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge") })
public class TestMDB implements MessageListener {

  private final static Logger LOGGER = Logger.getLogger(TestMDB.class.toString());
  public void onMessage(Message recmsg) {
    TextMessage msg = null;
    try {
      if (recmsg instanceof TextMessage) {
        msg = (TextMessage) recmsg;"Received Message from queue: " + msg.getText());
      } else {
        LOGGER.warning("Message of wrong type: " recmsg.getClass().getName());
    } catch (JMSException e) {
      throw new RuntimeException(e);


Click here to download for the source code, if you would like to run it, please run
  • mvn clean install 

under the mdb project directory.

And then deploy the WAR file onto EAP. 

It will start printing our messages if we send message in to the queue, so, go to A-MQ admin console at http://localhost:8181, login with admin/admin, click on  ActiveMQ -> amq -> queue -> queue/testQueue, and then on the righthand side, click on the Send Tab. 
Here you can send data and messages into queue. 

And the result will appear in the log.

That's it. :)

Fuse Integration Service - Setup JBDS and create first quickstart application

Before we go and start creating our first application, I want to show you how to setup your JBoss Developer Studio, create a small application from the quickstart example and then running it on Fuse Integration Service.

I am using JBoss Developer Studio version 9, you can find it here.
After download the

double-click it, and start installing with default values.

After successful installation, we will need install the plugins for Fuse, on JBoss Central view, select software update, select enable early access.

And select JBoss Fuse Development for the plugin,

Click on install, and we are all set to go!

First thing first, we want to create a Fuse project to deploy on the base of Fuse Integration Service, which is OpenShift. If you have not installed it, please go back to my previous post for instructions. So on your JBDS, right click and start creating the project. Select new, maven project, if you have installed the plugin correctly, you should …

Red Hat JBoss Fuse/A-MQ - Fuse and A-MQ Version 6.3 GA is released!

Fuse and A-MQ 6.3 GA has just went out. Maybe, you would think this is just only a minor version release why should I care? Hold your thoughts on that! Because they have done a lot of improvements and also added many new features into this release.

Besides various bug fixes and making sure Fuse Fabric is much more stable. There are two major change in this version update:

New Tooling in JBoss Developer Studio (JBDS) 9.1 GA. Newer Apache Camel version – Camel v2.17. I was really impressed by the work put in to make developing Camel application much simpler. First is the installation of tooling itself. Now it has a all-in-one installer so you don't need to worry about which plugins you need to check. See the videos below to see the new "Getting Started" of Fuse 6.3.

And If you notice from the above video, the presentation of camel route in JBDS has also updated. It fixed some of the miss representation of logic and making it easier to read.

RHTE - Supercharge your integration services

Red Hat Tech Exchange has taken place in Vietnam, Ho Chi Minh city two weeks ago, it is a great event held by Red Hat in Asia Pacific Region. It is open to all Red Hat partners who are interested in learning what Red Hat is doing recently, see what the trend of the open source world, basically it is a great event to share your knowledge and experience, to meet other enthusiastic people.

I am very fortunate to talk in this great event, to talk about the things I have been working on and even discuss it with many. Also got lots of great ideas too. So here are the slide.

My first talk was with Thomas Qvarnström about how to handle large size data in JBoss Fuse and how JBoss Data Grid can help in the situation.

Here is the agenda of the talk, we will be talk about this in the up coming webinar on 24th Sept.

Integration often involves storing, retrieving, and transforming data. Using a traditional database in your integration is likely to becomes a bottleneck that is expensive and hard to …
