Re: camel route with temporary queue seems to just hang

[Christian Schneider]

Hi Dana,

as far as I know you can not directly use a temp queue as a destination. 
Temp queues are special in jms as you ask jms to create a temp queue for 
you and then get its name.
So in camel you can use temp queues only for replies. I have no idea why 
there is a temp: syntax in the jms component as I think it can not work.

Another thing are dynamic queues. You just use them like a normal queue. 
The only difference is that the jms server creates it if it is not 
already present.

I'm still pretty new  to camel and activemq.

//env
java 1.5
spring 3.0.5
camel 2.6.0
activemq 5.4.2

I'm trying to create a route from a regular activemq queue to a temp queue.
I'm not 100% sure where I'm going wrong.
If I set my camel route from ->  to  to use a regular queue everything works
fine.

I'm thinking I'm missing super simple.  The request, reply works fine using
regular queues.  Any help would be a much appreciated!!

Thanks Dana
