I have an application deployed in Websphere which should push a message in a queue implemented in JBoss using HornetQ. That message will then be consumed by an MDB within another application (on JBoss). Is that even possible?
In summary:
WAS (producer) -> JBoss (consumer)
I think yes because the protocol JMS is shared, but what are the details? should I load JBoss with MQ libraries or is it all in the way I refer to the JBoss queue from WAS?
Thank you so much.
If the MDB deployed on JBoss EAP is receiving a message from a local queue in HornetQ, then you do not need to deploy any MQ jars.
All you will need to do is write a MDB application and read the messages in your onMessage(Message msg) method. It should be really as simple as that.
You can see an example of a MDB in the jboss eap quick start . The HelloWorldQueueMDB.java class is the one you might be interested in. Follow the code in that class and modify the destination annotation value for your particular HornetQ queue name (from standalone-full.xml or standalone-full-ha.xml or the full or full-ha profile in your domain.xml file).
On a side note, JBoss EAP 6.1 is quite old. I would highly recommend upgrading to JBoss EAP 6.4.13 or later.

i'm using Wildfly to deploy an EJB war that use an external messaging broker Apollo not the the one that come with wildfly ActiveMQ artemis.
What i must to do setup a JNDI configuration in standalone-full.xml file but there isn't any helpful tutorial to do this i don't know what exactly i need to change in the configuration to make this happen?
Is this post any help?
https://docs.jboss.org/author/display/WFLY10/Connect+a+pooled-connection-factory+to+a+Remote+Artemis+Server
I was able to use an external artermis broker (not the Wildfly container) following the above example.
Thanks to Maarten I was able to get basic ActiveMQ JMS topics and connection factories working in WAS. He has a nice write up in his reply to this topic: ActiveMQ 5.11 with WebSphere Application Server 8.5
But I cannot find a way to define any ActiveMQ JMS Activation Specs in the WAS admin console. And of course I need those in order to trigger my MDBs. ActiveMQ simply doesn't show up as a JMS provider when creating a new AS.
How do I configure Activation Specs in WAS using ActiveMQ as the provider? Am I missing a jar file?
activemq-client-5.11.0.jar
hawtbuf-1.11.jar
slf4j-api-1.7.10.jar
If you want to use Activation specification, you need to install ActiveMQ as JCA 1.5 compliant resource adapter. As far as I know, ActiveMQ provides resource adapter as separate install.
See also:
Deploying the ActiveMQ Resource Adapter into IBM WebSphere
Managing messaging with a third-party JCA 1.5 or 1.6-compliant messaging provider
ActiveMQ resource adapter
Listener ports are stabilized, and should only be used if provider doesn't support JCA.
Really straight forward once you understand (of course).
From the IBM Redbook mentioned above, sg247770.pdf, we need to configure ActiveMQ as a Generic JMS provider in WAS. And since we want to use Activation Specs, again from the Redbook, we need to use the ActiveMQ Resource Adapter, or rar file. There is a link on the ActiveMQ page to the latest rar, I don't need to provide it here. Once the rar is installed, using the WAS Console/Resources/Resource Adapters menu, you can configure J2C CFs, ASs, and administered objects including Queues and Topics from the rar configuration page. These will all have custom properties where you will enter your destinations, etc.
I am using tomcat as webserver. Planning to use active mq for messaging purpose. Just started learning about jms and activeMQ.
Gone thru https://activemq.apache.org/getting-started.html. What i have got is active mq comes with its own web
server(probably apache IS not sure). My question is what if I want to use existing tomcat server instead of installing
new server for active mq. Is it possible?
UPDATE: i think i can itegrate existing tomcat with https://activemq.apache.org/tomcat.html
Yes Apache ActiveMQ is a light-weight broker, so you can deploy it in Apache Tomcat as a WAR file. Or try Apache TomEE which comes out of the box with AcitveMQ.
http://tomee.apache.org/apache-tomee.html
If you deploy ActiveMQ as a WAR file then it does not come with its own web service, its only the standalone distribution of ActiveMQ that comes with Jetty as its web server. You just don't need to include Jetty in your WAR file with ActiveMQ embedded.
At Apache Camel we have an example of a WAR file with ActiveMQ and Camel as a WAR file you can deploy in Tomcat. You can take a look, and just remove Camel from the example:
http://camel.apache.org/activemq-camel-tomcat.html
See these:
http://blog.octera.info/2011/06/how-to-embed-activemq-in-tomcat/
http://activemq.apache.org/how-do-i-embed-a-broker-inside-a-connection.html
Basically, you just start a broker in your web application. If you need to retrieve some resource like ConnectionFactory or Destination(Queue/Topic), you can use Tomcat JNDI support to do this.
Is there any way to restart JMS in running JBOSS.
Use the web-console, admin-console or jmx-console depending on which version of jboss you are using. They are deployed in the default JBoss server config.
http://localhost:8080/admin-console
You may want to set the passwords though..

I need to write a Message Driven Bean. I'm using JBoss IDE 1.5. I understand the concept behind MDB's but I don't really know how to install the JMS provider (JBoss MQ? I think) and use it so that it will be used to broker my message to an MDB.
does anyone know of a tutorial I can use ?
JBossMQ is the default JMS provider in JBoss 3.2.x and 4.x but is replaced by JBoss Messaging1 in JBoss AS 5.0 (JBoss Messaging 1.x is the default JMS provider in JBoss AS version 5).
Depending on the version of JBoss you are using, you already have a JMS provider so I'm not sure what you want to install. And for the configuration part (e.g. how to create a Queue/Topic to which you could send messages), you have to provide some XML files.
Check the Configuration section of http://www.jboss.org/community/wiki/jbossmq and especially the Destinations page for JBossMQ. This blog post might help too.
Check the chapter 6.6 Configuring Destinations of the Jboss Messaging 1.4 user guide. This blog post might help.
Note that starting with JBoss AS version 5.1.0, there is an admin console that allows to create JMS Destinations (expand the "JMS Destinations" entry in the tree view, click on either Queues or Topics, and the in the right panel click the "Add a new resource" button) and/or Connection Factories.
1Starting from version 2.0, JBoss Messaging has been rebranded to HornetQ.
