Hi,

If camel can't send the JMS message into the jms queue, it will throw 
the exception , and camel will use the default error handler[1] (which 
will try to redeliver the message few times) to deal with this error, 
then the jetty consumer can get the error and send back an error message 
to the client.
So If you just want to send the OK message back to the jetty endpoint, 
you may need to the work like this
from("jetty:http://localhost:9080/myapp/myservice")
   .process(new Processor() {...})
    // set the exchange pattern, since there is no response from jms queue
   .inOnly()
   .to("jms:queue:some_queue")
   // set the out message for jetty consumer to send back to client
   .inOut().setBody(constant("OK"));
