Red Hat JBoss Fuse - Deploy a WAR file with Servlet

In normal integration project we built SOA architecture, or more recently microservice seems to be the hottest buzz word around, but no matter that how big or small the service is, it's still a service. In integration our primary job is to become the moderator between systems, allow systems to talk, communicate smoothly, by that, we have lots of protocols to work with, MQTT, AMQP for messaging, Restful JSON or SOAP XML for web service, Files, FTPS etc... But what if or end communication or response end is a human? We can't expect a human being to process a bunch of large text, XML or stream of bits, I mean, yes, some may, but not in most cases. There for we often process and simplify information on a page, that is readable by human. For that by creating a web application renders these data to users comes in very handy.

In java space, we will most likely to create a WAR file and run it on a Java EE container (JBoss EAP). But what about running the WAR file on Karaf container in Fuse? And how do I add my Camel file on to it? Here is how.

First, I am going to create a WAR project, just like what  we will normal do when creating a web application.  I prefer to use maven archetype for this.

And then we will need to add the dependency needed to run Camel route, please add the following camel related dependencies in pom.xml.

    <!-- Spring Web -->
    <!-- logging -->


Then we need to think about setting Spring, since all the Spring beans lives in ApplicationContext,we need to set it up. By setting the ContextLoaderListener it will load my camel files match *-context.xml and create an ApplicationContext for it.



And then we can start adding our Camel application. Here I am going to create a very simple Hello World Camel route, that prints out "Hello world" in every 5 seconds.

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns=""
        Simple camel route which send every one minute a message on the console.
    <camelContext xmlns="">
        <route id="timer-to-console">
            <from uri="timer://foo?fixedRate=true&amp;period=5s"/>
               <simple>Hello Web Application, how are you?</simple>
            <to uri="stream:out"/>


There are many options available to deploy our WAR application in JBoss Fuse, I am going to show you on of them, maybe later, if I have time, I can go through how to deploy through Maven plugins. But let's stick to the basics for now. First we do what we normal do to generate the WAR file.

mvn clean install

Go to JBoss Fuse, Install it, and make sure you have created Fabric. If you are not sure how, please check out my Fuse 101 Workshop. Once JBoss Fuse is started, go to http://localhost:8181. Create a container with Profile name feature-fabric-web

After container started. Go into container view, and in console, click on the OSGi tab. And on the top right corner, enter

  • war:mvn:com.redhat/springtest/1.0.0-SNAPSHOT/war?Web-ContextPath=springtest

and click the tick to install.

After install successful message appear, select it on the list and start it.

You will see the logs running under log console.

So, this is how you add Camel Route to your web application. That's all.

Red Hat JBoss Fuse - Getting Started with Fuse Integration Service 2.0 Tech preview

I just realized that I did not do a getting started for Fuse Integration Service 2.0 Tech preview before I did the pipeline demo, thanks for those of you who reminded me! :)

To get started with FIS 2.0, for people who has just getting to know the technology, here is how I interpret it. Basically, it's divide into two aspect,

1. Integration development, FIS uses Apache Camel as the core technology that creates, orchestrate, compose microservices into a super lightweight thin integration layer, and become the API provider and service orchestrator through exposing RESTful or messaging service endpoints. And you can choose to either package and run it with Spring-Boot or Karaf.

2. Application Deployment and Management, FIS takes advantages of OpenShift platform, and allows you to separately deploy the micro-integration service among distributed environment, at the same time takes care of the failover, high availability, load balancing and service lookup problem for you.

So, now we know …

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.

Old Camel Route
New Camel Route

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 …
