Hi
Yes this is possible. The solution is to use a queue where you "split" the
request. You can use a JMS queue or a the SEDA queues that Camel has
out-of-the-box.
http://activemq.apache.org/camel/seda.html
The transform DSL is used for setting the OUT body = the response to the
original caller.
Here is an example of such a scenariou. I have build a unit test to demonstrate
this:
public void testSendAsync() throws Exception {
MockEndpoint mock = getMockEndpoint("mock:result");
mock.expectedBodiesReceived("Hello World");
Object out = template.requestBody("direct:start", "Hello World");
assertEquals("OK", out);
assertMockEndpointsSatisfied();
}
@Override
protected RouteBuilder createRouteBuilder() throws Exception {
return new RouteBuilder() {
public void configure() throws Exception {
from("direct:start")
// send it to the seda queue that is async
.to("seda:next")
// return a constant response
.transform(constant("OK"));
from("seda:next").to("mock:result");
}
};
}
Med venlig hilsen

Subject: Synchronous/asynchronous bridge
Hi,
I am using Camel embedded in ServiceMix via the servicemix-camel service
engine.
I need to implement the following routing scenario:
HTTP Consumer BC ---> Camel ---> Transformation --> HTTP Provider BC
/|\ |
|______________ |
Basically, I receive a SOAP request through an HTTP endpoint in ServiceMix
and it gets directed to Camel. As soon as Camel receives it, it should
immediately return back a fixed response (<Response>OK</Response>), and then
it should invoke an XSLT Transformer, and should finally send the
transformed message to the HTTP Provider.
I am OK with the bit where I have to use a pipeline, but I don't understand
how to return the response half-way through the routing flow.
Could someone help me with this, please?
Thanks a lot!
