Routing from restlet to activemq

[Michael Dewitte <mi...@gmail.com>]

Hi,

I'd like to have a rest interface for my clients to publish events on a
topic (with some transformation and filtering in between). To do that, I
thought about using a route like this :
<camel:camelContext xmlns="http://camel.apache.org/schema/spring">
<route id="MyEventGateway">
<from uri="restlet:http://localhost:9080/Events?restletMethod=post"/>
<to uri="log:events" />
<to uri="activemq:topic:VirtualTopic.EventGateway"/>
</route>
</camel:camelContext>

But as restlet is an InOut endpoint, it seems by default to create a temp
queue to receive a response that is never sent, resulting in a timeout that
the client gets ("ExchangeTimedOutException: The OUT message was not
received within: 20000 millis.")

My question are :
- how can I sent the response to restlet ?
- is there a way to have a direct response to the rest client, just a simple
ack, so that I can process further without having to send a response ?
- what is the RobustInOnly Message Exchange Pattern ? I haven't found
explaination nor on the site nor in the book...
- Maybe have you got a better way of doing what I want ?

Thanks for any help,

Mike

Hi,
 you should be able to use
<inOnly uri="activemq:topic:VirtualTopic.EventGateway"/>

or use at <setExchangePattern pattern="InOnly" />
