Camel and spring XML

[Glenn Macgregor <gm...@pocketkings.ie>]

Hi All,

I have installed activemq 5.2.0 and see that a minimal set of camel functionality is included, activemq-camel.jar, camel-core, camel-jetty, camel-jms and camel-spring. I have added a route in my activemq.xml config file:

<route>
 <from uri="activemq:topic:el1"/>
 <to uri="activemq:topic:test1"/>
</route>

This route works fine, I get the message in the el1 topic listener and the test1 topic listener.

When I add a filter to the route:

<route>
 <from uri="activemq:topic:el1"/>
 <filter>
 <simple>header.testto = "test1"</simple>
  <to uri="activemq:topic:test1"/>
</filter>
</route>

I do not get the message in the test1 topic listener.

Is this EIP included in the default camel jars in activemq or do I need to install the camel disto?

Also is there a way to set the uri attribute of the from and to elements using JMS message variables like header.testto?

Thanks

 Glenn

Yes all EIP is included in camel-core.


The simple language DOES not support operators in Camel 1.x. This is a
new feature in Camel 2.0
So you can only test if there is a header or not in Camel 1.x

You can use xpath instead

<xpath>$testto = 'test1'</xpath>

where $testto will refer to the header with that name. Its a special
function added to xpath by Camel.

Do you mean something like the recipient list EIP?
