Routing an ActiveMq topic to an external broker.

Question

Hi All,

I have an ActiveMq topic which I wish to transform and share with an external broker. At present I have the following which performs the transformation:

<camelContext id="camel" xmlns="http://activemq.apache.org/camel/schema/spring"&gt;
    <route>     
        <from uri="activemq:topic:OriginalTopic"/>
        <to uri="xslt:file:///xslt/transformation.xsl"/>
        <to uri="activemq:topic:NewTopic"/>
    </route>
</camelContext>

However this just sends the message to the current broker network. I'd like to pass the NewTopic messages to an external broker only. I don't want to join the external broker using a <networkConnector .. > as only this topic should be send to the external broker and no others.

Is there a simple way to route messages to an external broker?

Many thanks.

UPDATE

The above method also has the disadvantage that subscribers to original topic no longer receive messages, is there a way to route to another destination whilst not losing the original topic?

Answer 1

Simply just define a spring bean with id activemq2 and have its brokerURL configured for the 2nd external broker.

Then the last to url will be: activemq2:topic:NewTopic

Answer 2

Just for the reference, you can filter destinations that will be forwarded in network of brokers. Take this configuration for example:
