In the docs we see



I'm using JMS queues. Assuming I have my queue wired to inChannel, does this mean that every single time a message is written to inChannel, ExampleServiceActivator.foo() will be called?

What if two messages are written to inChannel at the same time (or close enough. You know what I mean ) ? Will it kick off one thread per message and potentially process them concurrently? Or will the ExampleServiceActivator be invoked serially, once for each message?

I'm having an issue that I originally thought was a JMS issue, but now I think it's some manner of ServiceActivator issue, or an XA transaction issue.

Namely, I'm putting 5 messages into a queue but my service activator is only being invoked twice. As I look at the queue using Gems I can see the other messages are there... But they'll never be processed.

Any ideas?
