Now making sure I understood what you said the cause of the error
message is. Since the jetty-deployer is 'provided' scope it is not
added explicitly to the class loader for the console. The jetty-
deloyer has the interface and impl for JettyWebAppContext. Since the
jar that this interface is in is not explicitly added to the
console's class path (because of 'provided' if I understand
correctly) it barfs.
I'm not sure what the point is of listing it as "provided", if that's
what we're currently doing. I'm pretty sure it's not "provided" so we
might as well either not list it or list it as a regular dependency.
We should also make sure to do the same thing for the Tomcat and Jetty
console modules, just each with their respective JARs.
Note that it's not a "big barf" -- it just means we won't be able to
call server-specific methods using the interface that couldn't be
loaded (only the generic methods in the superinterface). That's not
necessarily disastrous, but it would be nice if we could avoid it. It
depends on whether we'd normally want to be able to use the extra
methods or not.
I guess there's also a third option, which is to get rid of any
functionality in the server-specific intrefaces (putting everything in
the generic interface) and force each server to just throw an
UnsupportedOperationException for any methods that it can't handle.
Thanks,
