You don't need to create your own threads for that (though you could). >From your component or endpoint (you could simply use servicemix-bean for >that), just create the four JBI exchanges and send them asynchronously. On each exchange, set a correlation id (you can use the id of the exchange received). When you have received all the exchange you need, just aggregate those and set the out message from the original exchange. Note that camel or servicemix-eip may help there: they both can do aggregation, but given that you'll have to split the exchanges yourself, it may be easier to just write an endpoint and do the whole.
