I fully agree - the /admin provides few informations and services, but
it's user interface is very bad ( and not only from a graphical point of
view ), and incomplete.

I do add new pages and features - every time I have some time - but it
needs much more.

Probably someday I'll start a major refactoring for /admin - at least
separate the "server side" and the "ui", clean up the taglibs, etc.

For a non-web-based GUI it should be possible to control tomcat via URL
requests ( or direct calls ).

Agree - but remember this is open-source, with all it's benefits and 
problems. 

It would be nice to have better error messages - if someone would 
write the code ( or at least more docs ). 

Probably a good solution would be to stop using server.xml as a
user-modifiable config file, and work on a GUI that will expose only 
a controled set of options. 

( advanced users will still edit server.xml, but most users shouldn't
touch it ). 

One way or another - tomcat is a collection of modules, like apache. The
config file is not setting some tunnable parameters, but it's wiring up
the whole tomcat. It has a lot of power - but it's probably not the best
thing for users.

Yes, but I can hardly find time for one. I would love to work on both -
but so far I coulnd't find  people to help on the /admin, and I'll
not start it alone.
( well, Larry and few others helped a lot - but he seems to have even less
free time than I have ).

Well, thanks for the feedback - and even more thanks if that leads to some
code contributions.
