There should be enough of Camel inside the ActiveMQ broker to do most
of what you need; but you might wanna add a few more jars depending on
how complex your camel routes are.

e.g. the out of the box ActiveMQ comes with core Camel support
(camel-core) within support for files, SEDA, XSLT and mock testing
endpoints - along with spring support (camel-spring) and JMS support.

However if you wanted support for other components; such as mail,
you'd need to add more jars (e.g. camel-mail and its dependencies such
as JavaMail etc)

Could you show me the stack trace?

Here's all the docs we've got so far...
http://activemq.apache.org/camel/user-guide.html

in particular
http://activemq.apache.org/camel/xml-configuration.html

which includes a link to the online reference for the XSDs etc

Hopefully the documentation will improve soon.
