ExchangeTimedOutException

[Darren Davison <da...@davisononline.org>]

hi

I have a route that takes a message from a queue, passes it to a
servicemix-http component and places the response on another queue.

When I inject a message to the input queue, I see the http component being
invoked and I see the output message placed on the output queue (can browse
or peek it using Hermes JMS for example).  All looks good, however, 20s
after this I get a org.apache.camel.ExchangeTimedOutException and the output
message is deleted from the output queue.

What am I missing here?

Cheers.


route as follows:

<camel:route>
  <camel:from uri="activemq:IN"/>
  <camel:inOut uri="nmr:{urn:oms}foo:fooEP"/>
  <camel:to uri="activemq:OUT"/>
</camel:route>


servicemix component config:

<bean class="org.apache.servicemix.common.osgi.EndpointExporter" />
<context:property-placeholder
    location="file:${karaf.home}/etc/oms.properties"/>
    
<http:provider service="oms:foo" 
               endpoint="fooEP"
               locationURI="${location.url}">
    <http:ssl>
        <http:sslParameters keyPassword="${ssl.cert.keypass}" 
                            keyStore="${ssl.cert.keystore}"
                            keyStorePassword="${ssl.cert.keypass}"  
                            trustStore="${ssl.fp.cert.truststore}"
                            trustStorePassword="${ssl.cert.keypass}"/>
    </http:ssl>
 </http:provider>

Hi Darren,

There are a few reasons, why this may be happening.
Keep in mind that camel will have to convert the in message to xml in order
to send it to nmr.

Hi,

this worked in that the response mesasge now remains on the output queue.
Thanks for that.  Unfortunately, the input message is going missing before
it reaches the backend service.

Trace logging shows that a 0 byte length request is being sent to the
back-end service which predictably returns an error response.  I'm in the
process of setting up a test harness to remove the SSL complexity I have
with the real service, but in principal the 2 line route described in XML
below is causing the servicemix-http component to view the incoming message
as being empty.

What fundamental thing am I not seeing in working with camel-nmr??  Is there
anyone who can tell me why this should fail to transmit an IN message to the
servicemix Exchange?

Cheers,

I think that the problem is that your http endpoint is sending the out
message to the OUT queue and the response never reaches the consumer
(activemq:IN).

I would try the following:

<camel:route>
  <camel:from uri="activemq:IN?replyTo=OUT"/>
  <camel:inOut uri="nmr:{urn:oms}foo:fooEP"/>
</camel:route>
