Yes, sorry about that, long time I've not used it :(

The only practical issue is if someone ever tries to packages a webapp.jar as
the build-jar-repository will do lookups on directories too (to allow
replacing transparently foo.jar with a foo subdir containing a set of jar
files)

Anyone will do, being consistent with php would of course be nice to users.

"normal" way with Java deployment? That's an oxymoron. The only Java
deployment conventions so have have been written by distro people. I'd suggest
to look at the php webapps included in the distro, derive something similar
for Java, and write a formal Fedora packaging guideline so others have an
answer to your question. Everything but the location of the tomcat/jetty/jboss
config files is likely to be identical no matter what the webapp language is
