Re: where things like # retry attempts should be configured:

I added a subtask to backport that.

I agree with you about consistency. In 4.2 the config of default snapshot mode/interval may not be removed from the Tomcat SAR in order to maintain compatibility in a minor release. But IMHO they don't really belong in the Tomcat SAR.

Right now I'm thinking that:

1) Everything that can be varied per webapp should be configurable per webapp (i.e. in jboss-web.xml).
2) The ability to set an overall default in the Tomcat SAR is useful, but it adds clutter to the SAR config. If you read the SAR's -service.xml, you'll see what I mean. So, we should only offer the ability to set the default if:

a) it's a value people are likely to change
b) the change is something they want applied to multiple webapps

Of the UseJK, snapshot and retry configurations, IMHO only useJK meets these criteria.

Opinions on this are most welcome; on JBAS-3460 I mentioned I wanted a forum discussion about this general issue, so no reason this can't be that discussion. :-)
