Camel 2.0+ functionality - dynamic route and endpoint creation?
I'm very interested in the Camel architecture and in what it supports. My
only problem thus far has been in the static nature of the definitions of
the routes and components. I am curious as to what extent Camel can handle
dynamic configuration. I have spent quite a bit of time reviewing the
documentation for both the current version of Camel and the milestone
release for Camel 2.0, and I have been unable to find exactly what I'm
looking for. I'm hoping that someone in the community can either steer me
to the appropriate information, or let me know that the architecture simply
can't handle what I want.
Here is the scenario. I'd like to be able to start up a more or less
'blank' Camel instance, with only one running bean and no existing routes.
I would like to put that bean in charge of creating other beans/endpoints
and making and changing routes between them.
So, the questions are:
- Can I programatically create and delete beans/endpoints and
create/mutate/delete routes with no prior configuration? i.e. there is zero
hardcoding of the definitions of the beans/endpoints/routes; that will all
be supplied to the sole running bean as a parameter.
If not, can anyone speculate as to the amount of work that would be required
to adapt the architecture to support this? I'd be interested in
contributing this type of functionality to the project if it seems that it
would fit with the existing infrastructure, but if not I'll have to look for
another mechanism to implement this.
If it helps, I can elaborate further on what I'd like to implement.
Thanks in advance,
- Michael

No, I never saw it until now, so thanks for reposting it.

Thanks for the answer. I had actually found the StartAndStopRoutesTest, but
since I only found it filed in Camel Issues and not in the documentation I
wasn't sure what its status was. I didn't find any other unit tests like
that, but I'll look around more carefully.
Regardless, that's exactly the kind of thing I'm looking for. I'm going to
write up some code and see if I can make it do what I need. Thanks for the
assistance.

Hi
Did my mail ever get to the user forum? I had some mail issues with my

In Camel 2.0 James added the camel web-console that is a web based
console for dynamic routing and viewing routes and the likes.
There should be a link to it on the camel wiki pages. Just use the
google custom search bar.
And James recently replied to the Google Summer of code Project to
improve the web console

Yes you can at runtime add routes etc.
There are methods on CamelContext to do that.
You can build the routes using the model classes. That is what the DSL does.
And there should be a few unit tests in camel-core about mutating the
route at runtime.
For instance: StartAndStopRoutesTest
