Hello Alejandro.
Thank you once again for your response.

Good. One worry less on my list :-)

A colleague of mine is quite good at working with hibernate. I'll let
you know, if I find a solution to that problem.

It's not used for authentication. It's used to serve "personnel master
data", e.g. who is in which department, which division does the
department belong to, accounting information, report-to-chains etc.
For authentication I'd use other tools (i.e. we run a CAS server and
could also use shibboleth).

OK. Good to know, that -- just in case -- there are options left to try.

I did read it first. And then the quick start, the overview, most of the
user's guide and the articles. I read most of the information on the web
site.
Currently my task is evaluating -- in a sense of "read specs" and/or
"try a tutorial". I got my feet wet, but my colleagues ask questions,
that I could not answer from the documentation. That's why I pass those
questions on to the mailing list. I am sorry, if you consider my
questions inappropriate.
Basically, all I have to do, is find out, what the different candidates
(amongst them Trails) are capable of and how well they support different
tasks. Then I'll present that to the "evaluation board" and they'll pick
something. And only *after that* I'll go through the trouble of learning
the necessary tools (maven2, ant, hibernate, tapestry, ...) in detail.
As far as I can tell, I suppose, that once the decision is made, I'd
even be allowed to contribute to Trails' documentation during work time
instead of writing "internal" docs. My boss is quite open minded and
generally likes open source and supports giving back to the community.
He is also a Java enthusiast, so I think that Trails has a good chance
of being chosen.
Many thanks and kind regards,
Daniel
