Service provider ServiceMix + Camel

I am trying to send a messasge to an ActiveMQ queue from a web service that is deployed in ServiceMix 5.4.0. For this reason, I get the producer template from the camel context and send the message like this:

ProducerTemplate template = camelContext.createProducerTemplate();
template.send(
    "activemq://ExecutePaymentInputQueue",
    new Processor() {
        @Override
        public void process(Exchange exchange) throws Exception {
            exchange.getIn().setBody(
                ...
            );
        }
    }
);

There must be an open JTA transaction when the message is sent (see the config for declarative rams in the blueprint.xml file).

The problem is that the producer appears to be ignoring the jta transaction and the message is put on the destination queue outside of that transaction (immediately after the dispatch method returns). How can I change this behavior and force the producer to join the JTA transaction?
