I found the solution by myself:

Hi,

I need to configure Jboss jndi Context to connect to a remote activeMQ broker. Using tomcat this configuration is very simple and it's sufficient define the jndi resource on context.xml as follow: 

<Context>
<Resource
    name="jms/ConnectionFactory"
    auth="Container"
    type="org.apache.activemq.ActiveMQConnectionFactory"
    description="ActiveMQ JMS Connection Factory"
    factory="org.apache.activemq.jndi.JNDIReferenceFactory"
    brokerURL="tcp://remoteBroker:61616"
    brokerName="NetMJMSBroker"/>

<Resource
    name="jms/topicTest"
    auth="Container"
    type="org.apache.activemq.command.ActiveMQTopic"
    description="ActiveMq topic"
    factory="org.apache.activemq.jndi.JNDIReferenceFactory"
    physicalName="topic.test"/>
</Context>

Adding the following jars in the classpath:

activemq-core-5.3.1.jar
commons-logging.jar
geronimo-j2ee-management_1.0_spec-1.0.jar
geronimo-jms_1.1_spec-1.1.1.jar

And nothing more!! it works successful!!

Now,
I would like do the same on Jboss:
Despite the web container embedded on Jboss is still tomcat, I tried to use again the same context.xml described above, but without success!
Even though I put it under META-INF or WEB_INF or in another place, there's no way to Jboss to load this file! 
Anyone could confirm this ?

Said that, second question:
Assuming that I can configure jms datasources using only jboss specifics descriptors files, like: jboss-web.xml, jboss-application.xml and, *-ds.xml to define jms datasources...
The only documentation that I found about it is the activeMq jboss integration. 
My question is:
Should I add all the following resources on jboss classpath even though I needn't to configure a broker locally but only configure jndi context to connect to a remote broker ? 

-add activemq-jms-ds.xml
-add activemq-rar-5.3.1.rar
-configure META_INF/ra.xml under activemq-rar-5.3.1.rar
-configure broker-config.xml under activemq-rar-5.3.1.rar

Third question:
Anyway, I tried to configure the above resources to try to connect to a remote broker but without success. 
Following how I configured these resources:

- activemq-jms-ds.xml
...
<tx-connection-factory>
<jndi-name>jms/ConnectionFactory</jndi-name>
<xa-transaction/>
<track-connection-by-tx/>
<rar-name>activemq-rar-5.3.1.rar</rar-name>
<connection-definition>javax.jms.TopicConnectionFactory</connection-definition> 
<ServerUrl>tcp://remoteBroker:61616</ServerUrl>
</tx-connection-factory>
...

- ra.xml
...
<resourceadapter>
<resourceadapter-class>org.apache.activemq.ra.ActiveMQResourceAdapter</resourceadapter-class> 
<config-property>
            ...
<config-property-name>ServerUrl</config-property-name>
<config-property-type>java.lang.String</config-property-type>
<config-property-value>tcp://remoteBroker:61616</config-property-value>
            ...
</resourceadapter>
...

- broker-config.xml
...
<broker useJmx="true" useShutdownHook="false">
...
<transportConnectors>
<transportConnector uri="tcp://remoteBroker:61616"/>
</transportConnectors>
</broker>
...


This is the outcome:
/ERROR [BrokerService] Failed to start ActiveMQ JMS Message Broker. Reason: java.io.IOException: Transport Connector could not be registered in JMX: Failed to bind to server socket: tcp://remoteBroker:61616 due to: java.net.BindException: Can't assign requested address/ 


Thanks a lot!
