Dynamic CBR with camel

I have been successfully using camel to perform routing
between jbi,  
jms, logs, etc. However, all of the routing has been static
as  
defined in the camel-context.xml. What is the best way to
acquire the  
NMR's CamelContext object to add routes dynamically from
other services?

Thanks!
Aaron

Sounds cooll..
Could you please highlight  at highlevel the procedure that
you followed.

cheers.

Sure, here is the basic idea:

- Create a camel service unit based on the example. Within
the  
RouteBuilder class, use DSL to create routes between
endpoints . I'm  
using xpath predicates etc. I'm also using camel JBI
endpoints to  
serve as proxies to other services in a clustering
environment.
- Create several lightweight components for the application.
Provide  
the static wiring between POJOs within the component
servicemix.xml  
file (including defaults etc)
- Create a plain service assembly that contains the above
service units
- Deploy the service assembly

At some point during normal operation, a new route needs to
be  
created. Is the camel context available through JNDI or
something  
similar? I'm thinking the right answer may be to deploy
another camel  
SU that has the capability for dynamic configuration. This
suggests a  
better design since the routing logic is separate from the
application.

Just thinking out loud... comments are welcome.

There is no global camel context.  When you deploy a SU to
the Camel
SE, a context will be created for this SU.   Though, you
should be
able to create a new Camel context and add JBI routes to it;
you just
need to feed it with a ComponentContext at some point.
