22.11. Configuring the HornetQ JCA Adapter for Remote Connections

Procedure 22.11. Configure an RA adapter to connect to two remote JBoss EAP instances

1. Create outbound socket bindings:

   <outbound-socket-binding name="remote-jms-server-a">
   	<remote-destination host="${remote.jms.server.one.bind.address:127.0.0.1}" port="${remote.jms.server.one.bind.port:5445}"/>
   </outbound-socket-binding>
   <outbound-socket-binding name="remote-jms-server-b">
   	<remote-destination host="${remote.jms.server.two.bind.address:127.0.0.1}" port="${remote.jms.server.two.bind.port:5545}"/>
   </outbound-socket-binding>

2. Create two netty connectors:

   <netty-connector name="netty-remote-node-a" socket-binding="remote-jms-server-a"/>
   <netty-connector name="netty-remote-node-b" socket-binding="remote-jms-server-a"/>

3. Create the RA configuration using the two netty connectors:

   <pooled-connection-factory name="hornetq-remote-ra">
     <inbound-config>
       <use-jndi>true</use-jndi>
       <jndiparams>java.naming.factory.initial=org.jboss.naming.remote.client.InitialContextFactory;java.naming.provider.url=remote://${remote.jms.server.one.bind.address}:4447,${remote.jms.server.two.bind.address}:4547;java.naming.security.principal=${user.name};java.naming.security.credentials=${user.password}</jndi-params>
     </inbound-config>  
     <transaction mode="xa"/>  
     <user>${user.name}</user>  
     <password>${user.password}</password>  
     <connectors>  
       <connector-ref connector-name="netty-remote-node-a"/>  
       <connector-ref connector-name="netty-remote-node-b"/>  
     </connectors>  
     <entries>  
     <entry name="java:/RemoteJmsXA"/>  
     </entries>  
   </pooled-connection-factory>

4. Annotate the MDB to use the resource adapter using the @ResourceAdapter annotation:

   @MessageDriven(name = "InQueueMDB", activationConfig = {
   @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"),  
   @ActivationConfigProperty(propertyName = "destination", propertyValue = "${hornetq.in.queue.short}"),  
   @ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"),  
   @ActivationConfigProperty(propertyName = "useJNDI",propertyValue = "true")  
   },mappedName = "${hornetq.inf.queue.long}")  
   @ResourceAdapter("hornetq-remote-ra")

5. Run the following CLI commands to enable property substitution in order to use properties in deployment descriptors:

   /subsystem=ee:write-attribute(name=jboss-descriptor-property-replacement,value=true)
   /subsystem=ee:write-attribute(name=spec-descriptor-property-replacement,value=true)
   /subsystem=ee:write-attribute(name=annotation-property-replacement,value=true)

6. Create an external context to find the remote destinations in order to send message from the MDB:

   <bindings>
   	<external-context name="java:global/remote" module="org.jboss.remote-naming" class="javax.naming.InitialContext">
   		<environment>  
   			<property name="java.naming.factory.initial" value="org.jboss.naming.remote.client.InitialContextFactory"/>  
   			<property name="java.naming.provider.url" value="remote://${remote.jms.server.one.bind.address:ragga}:4447,${remote.jms.server.two.bind.address:ragga}:4547"/>  
   			<property name="java.naming.security.principal" value="${user.name}"/>  
   			<property name="java.naming.security.credentials" value="${user.password}"/>  
   		</environment>  
   	</external-context>  
   </bindings>

7. The MDB code would look like:

   @MessageDriven(name = "InQueueMDB", activationConfig = {
   	@ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"),
   	@ActivationConfigProperty(propertyName = "destination", propertyValue = "${hornetq.in.queue.short}"),  
   	@ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"),
   	@ActivationConfigProperty(propertyName = "useJNDI",propertyValue = "true"),  
   	@ActivationConfigProperty(propertyName = "hA", propertyValue = "true")  
   },mappedName = "${hornetq.inf.queue.full}")  
   @ResourceAdapter("hornetq-remote-ra")  
   	public class InQueueMDB implements MessageListener {  
   		private static final Logger log = Logger.getLogger(InQueueMDB.class);  
   		@Resource(lookup = "java:global/remote")  
   		private InitialContext context;  
   		@Resource( name = "${hornetq.jms.connection}")  
   		private ConnectionFactory  qcf;
   		public void onMessage(Message message){  
   		try {  
   			if ( message instanceof TextMessage){
   				Object obj =  (Queue) context.lookup("/jms/queue/outQueue");  
   				qConnection = (QueueConnection) qcf.createConnection("quickuser","quick123+");  
   				qSession = qConnection.createQueueSession(true, Session.SESSION_TRANSACTED);  
   				qSender = qSession.createSender(outQueue);
   				qSender.send(message);

8. You must remember that the hornetq RA module contains remoting-naming dependency for the MDB code given above to work:

   <module xmlns="urn:jboss:module:1.1" name="org.hornetq.ra">
   	<properties>  
   		<property name="jboss.api" value="private"/>  
   	</properties>  
   	<resources>  
   		<resource-root path="hornetq-ra-2.3.25.Final-redhat-1.jar"/>  
   		<!-- Insert resources here -->  
   	</resources>  
   	<dependencies>  
   		<module name="org.hornetq"/>  
   		<module name="org.jboss.as.transactions"/>  
   		<module name="org.jboss.as.messaging"/>  
   		<module name="org.jboss.jboss-transaction-spi"/>  
   		<module name="org.jboss.logging"/>  
   		<module name="org.jboss.remote-naming"/>  
   		<module name="javax.api"/>  
   		<module name="javax.jms.api" />  
   		<module name="org.jboss.jts"/>  
   		<module name="org.jboss.netty"/>  
   		<module name="org.jgroups"/>  
   		<module name="javax.resource.api"/>  
   	</dependencies>  
   </module>

9. You must also add org.hornetq to global modules so the JMS API is visible to the application:

   <global-modules>
   	<module name="org.jboss.common-core" slot="main"/>
   	<module name="org.hornetq" slot="main"/>
   </global-modules>
