Alex,
Regarding the need to start/stop something along with the Component without
creating a subclass, you should leverage the Service class and add it to the
Component#services list. A Service has start() and stop() method that get
invoked by the Component.
Regarding the JEE deployment, the ServerServlet adapter will look for a
"/WEB-INF/restlet.xml" file to configure the Component. It should work well for
you.
Best regards,
Jerome

Well, I've filed a couple small enhancement requests but I really have more
things that I haven't started yet in mind.
For just about every project where I've used Restlet, I've developed a custom
XML configuration for the component.
I did not switch over to try to use the XML configuration provided by the
component when it became available.
My needs are somewhat more than what is provided by the current configuration
XML. My current theory is that I should be able to add to the configuration
XML in Restlet to provide what I need. It doesn't look like I'm that far away.
For example, in my Xeerkat [1] project, I use this XML to configure an agent:
An agent binds a number of protocols running for the server and then connects
to the XMPP id. In reality, what I should be doing is attaching the services
to the host or internal router and then exposing them via internal proxies
between the actual Application instances. I can do a lot of that with the
current XML configuration + my 'href' enhancement.
One issue I'll have to address is that a lot of my current systems define
global parameters/objects that are then used by applications within a
particular host. In my Component instance, I copy those particular objects as
attributes in the child Context instance created for those applications. I'll
have to see if there is a good way to extract and represent that configuration
pattern.
The XML configurations in my Atomojo [2] project are much more complicated to
convert over and I'm not sure that is appropriate there but I do have a few
candidates there as well.
Also, I keep developing the same kind of Component that needs to do something
at start/stop but otherwise does exactly what the Component class does now.
I'd like to be able to configure a "module" that is started and stopped with
the component so that I don't have to subclass Component.
I'm also curious as to how this kind of configuration XML is used in J2EE
hosted environments. I just run my restlet instances directly using Jetty or
Grizzly. I'd like this projects to be able to run in servlet containers as
well but I don't see any good examples of people doing this with the XML
configuration files. I'd like to know if anyone is doing that.
