Could you say a bit more about why you need to do this?

I've been busy with the OASIS work so haven't had a chance to reply to
this yet but i don't want it to look like silence means consensus. I
think we can greatly simplify this webapp and servlet host behaviour
as its got quite unnecessarily complicated. Will hopefully have more
time to spend on it next week.

WebappServletHost has the lowest ranking to favor host-jetty. Having a name
attribute allows us to find the WebAppServletHost in the web application
environment by name.
Thanks,

I'm still not sure I understand why the name is needed, why can't the
WebServletHost use the ranking like the OSGi ones?

I now removed the need to start the ServletHost in the module activator.
Multiple ServletHost implementations can be available in a Tuscany
distribution. We still need to pick one depending on the environment.
In the WebServletHost case, the web application wants to use WebServletHost.
I found that using a name as key is the simple way.
The OSGi world has a similar case where multiple services are registered
under the same interface. OSGi allows us to look up a particular instance
using a filter (a query on the properties) or by default the one with the
highest ranking. Actually, we use the OSGi service registry as the extension
point registry for the OSGi-enabled Tuscany runitme.
Thanks,
Raymond
