Creating JMS temporary destinations
I can't seem to find any documentation or examples that show how to create a
temporary queue/topic endpoint for ActiveMQ or JMS components. Is this
supported?

Thanks for the response, but that link doesn't discuss using Camel and
doesn't discuss creating temporary queues/topics. My current goal is not to
implement a request-response setup but to create a temporary private message
channel.

Yes!

I was assuming that
jms:tempQueue:<name>
would lazily create a new temporary queue if a temporary queue is not
registered by that name. We could then add some way to set the
temporary destination manually if required if you wanted to reuse an
existing temporary destination.

Thanks James, I appreciate the help.
If temporary destination URLs are going to be supported, will the ability to
create a temporary destination also be supported (either explicitly or in
the url somehow) -- otherwise you can only use camel on one end of a
communication over a temporary destination without dropping down to the raw
JMS api.
Perhaps 2 different url syntaxes could be used, 1 for creating a new temp
dest and another for using an already created one:
jms:newTempQueue
jms:tempQueue:<name>

We don't currently support the explicit creation of temporary
destinations yet in camel-jms.
But I guess we could support some kind of syntax like...
jms:tempQueue:foo
which would refer to a named temporary queue (ditto for tempTopic).
We'd just have to put a warning on the component that you cannot use
CACHE_NONE cacheLevelName value for this to work; as otherwise the
Connection would not be reused (which would mean it would be closed so
that the temporary destination would become closed).
I've raised a JIRA to support this...
