Getting list of contexts or getting context by name

[Gustav Sinder <gu...@ferrologic.se>]

Hi,

I'm working on a solution where I dynamically setup/remove routes based on external configuration. So far so good, it works good, a manager route handles this just good.
A thought would be to place the dynamic routes in another context. I can create new contexts from within the Java without problem but I can't seem to find a way to either list the active contexts and/or get a context by its name.

Also, are there any drawbacks on using another CamelContext instead of placing it all in the same one where the "manager route" also runs?

Thanks
/Gustav

Hi,

Correct, it's Camel Context I was thinking of.
Thanks, I was suspecting that the context is only aware of itself and others created from it. I'll stick with the same Context for the dynamic ones.

Regards
/Gustav

I just assume the context means Camel Context, am I right?
If you create the Camel Context you need to manage it yourself. I don’t think it is possible to look up the other Camel Context from the route which only knows about the CamelContext holds it.
There are some components can only be used to talk each other within the same CamelContext, such as seda, direct. And we use these component to glue the routes. 

So my suggestion is you keep the dynamic routes in the same CamelContext, unless you don’t want them talk to each other.
