I'm a newbie trying to implement the scatter-gather patten using web services only. I say "web services only" because all the examples I've seen implementing this pattern involved a message queue so not sure this can even be done.
My problem I'm hitting is when I output what's suppose to be gathered. In a multicast tag, I have two web services being called via jbi endpoints (they are set up as http providers). I then send the results to my aggregation strategy code. Finally, I print to the logs what was gathered. However, instead of outputting a result containing two messages, it only outputs one message. After a bit of testing, I noticed it only outputs the message from the last service called (based on my server log and order in camel-context.xml file).
I modified the bridge-camel example that came with servicemix as follow:
1) in the client and bridge-jms-su code, I did nothing since I don't need it.
2) in the bridge-http-su code, I added two http providers that take soap messages.
3) in the bridge-camel-su, I added the source code for my aggregation strategy and I modified the camel-context.xml (to remove references to the jms endpoint and add my own logic).
new camel-context.xml (unnecessary content hidden for simplicity, hopefully)

My aggregation stategy follows Torten's (http://tmielke.blogspot.com/2009/01/using-camel-aggregator-correctly.html) since I just want to combine the messages.
I've tried adding the strategy reference to the multicast tag (with no aggregrate tag) and the aggregate tag, individually, with no desired results.
