Hi James,
Thank you very much for your prompt faster-than-light reply!
That's exactly what I was looking for.
Just as a side note regarding Camel docs, in the FAQ comparison (ie
http://activemq.apache.org/camel/how-does-camel-compare-to-servicemix.html)
the newborn spring-integration is not compared (even if I have my own ideas
on the difference).
Thanks,
Regards,
S=C3=A9bastien.
