JBoss Fuse/A-MQ - Easy way to achieve fault tolerant messaging Part 2

So here is the step by step video to create Failover Client I promise last time.
Before you begin, please make sure you have created the Master/Slave broker beforehand.
Here are the videos:
  • Create Master/Slave Broker
  • Create Client Camel Application

You can find my sample code in github:
https://github.com/weimeilin79/failoverdemo

Before begin, there are some setups you need to do,
Download JBoss Fuse from http://www.jboss.org/products/fuse/overview/



Add fabric server passwords for Maven Plugin to your ~/.m2/settings.xml file the fabric server's user and password so that the maven plugin can login to the fabric.

<server>
  <id>fabric8.upload.repo</id>
  <username>admin</username>
  <password>admin</password>
</server>

There are 2 ways to tackle this example, First is to everything manually, create a Master/Slave Broker, build the client Camel Application from scratch and then deploy them onto Fuse. Second way is to everything install and configured and just to play with it.

So, in side my github project, you will find 2 shell scripts

  • init.sh
    • This is an simple installation, it basically just install the Fuse and setup the fabric for you, with this setting, you will need to follow along the 2 videos or the instructions from last blog (Part1) and find all the related code here
  • install-all.sh  
    • This shell will install everything for you. Including setting up the broker, creating a container, and then deploy the camel application on to Fuse container. 

Have fun with this demo, and please, if you are a window user, feel free to add the window .bat file and contribute back! Thanks!

Hello Christina,

It's Waldemar again. I'm having some problems to execute this example. I tried to download it from github and to execute the blueprint.xml as "local camel context (without test)" as showed in the demo video. It does not run (as presented in the video) and I got the following error message:
java.lang.IncompatibleClassChangeError: Found class jline.Terminal, but interface was expected
at org.apache.karaf.shell.console.jline.TerminalFactory.destroy(TerminalFactory.java:42)
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
...


Then I tried to deploy it in a Jboss fuse that was running locally. And I got a failure in building with the following error message:
[ERROR] Failed to execute goal io.fabric8:fabric8-maven-plugin:1.2.0.redhat-046:deploy (default-cli) on project failoverdemo: Execution default-cli of goal io.fabric8:fabric8-maven-plugin:1.2.0.redhat-046:deploy failed: Unable to load the mojo 'deploy' in the plugin 'io.fabric8:fabric8-maven-plugin:1.2.0.redhat-046' due to an API incompatibility: org.codehaus.plexus.component.repository.exception.ComponentLookupException: io/fabric8/maven/DeployToProfileMojo : Unsupported major.minor version 51.0

[ERROR] urls[1] = file:/Users/neto/.m2/repository/org/eclipse/aether/aether-api/0.9.0.M2/aether-api-0.9.0.M2.jar
...


And finally, I tried to execute the init.sh (and the init_all.sh), any container is created and I got the following message:
retrying (attempt 1) ...
retrying (attempt 2) ...
retrying (attempt 3) ...
64451 [pool-2-thread-1] WARN org.apache.sshd.client.keyverifier.AcceptAllServerKeyVerifier - Server at /0.0.0.0:8101 presented unverified key:
Waiting for container: root
Waiting for container root to provision.
Using specified zookeeper password:admin
To stop the backgroud Fuse process, please go to bin and execute stop
...

Finally, I followed step-by-step the demo guide. And I configured everything else (MVN_HOME; I put it in my OS Path, the .m2/settings.xml). Do you think that it is due to a configuration problem, or have you any idea for a solution to my problem?

Thanks for the attention,
Neto

Hi Christina, I have a Cluster Master / Slave MQ installed in 3 nodes, the temp is that I try to scalar and always process the messages approximately 1000 requests per minute, whatever I do I always have the same processing time, which parameter I have to fine tune So that the processing is faster?

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

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 …
