By the time, I created this pom.xml, 1.5 was not officially released
yet, and I copied a pom.xml from some other sandbox project. We could
very well depend on the latest development version or on the released
version, whatever seems more appropriate, or even drop the parent
reference as well.

Sorry, this was my just initial approach. I quickly felt that abdera
was extensible enough to fill the atompub binding part. In order to
have a minimal startup time, so that I could tweak the responses the
way I wanted them, I used this programmatical test setup. It surely
makes more sense to have jackrabbit.war extended by jcr-cmis, as you
suggest. I'm not sure, however, whether we can still use the abdera
servlet then.

Axis is the only framework I heard of right now, but I was hoping that
there is some better approach ;)

I'd prefer having a specific component.

As far as I know, this hasn't been done yet.

Sounds good to me. I started creating a couple of interfaces from the
spec, but if we can have them generated through WSDL and use them in
the atompub part as well, even better :)

Kind regards
