-------------------------------------
Hi Mike,
About camel-mail can't work on karaf out-of-box, I think the reason is that
karaf is designed to keep as small/simple as possible, it not by default ship
camel features with it and so not tune the jre.properties/customer.properties
to accommodate camel related features by default. However, Apache servicemix
already do this job for you, you can take a look at the
jre.properties/customer.properties shipped with sevicemix and you can tell the
difference with that in karaf. Actually you can edit
$SMX4_HOME/etc/org.apache.karaf.features.cfg and easily disable JBI components
there if you don't need the JBI stuff, which can make servicemix as simple as
karaf and it's a better start to install camel related features there.
Regards
Freeman
