Janne,

There are a variety of different problems that are common to
a
first-time install, particularly those that involve
unmodified
jspwiki.properties files. My suggestion would be to break
out
the known categories of errors and handle them in such a way
that the error message names the property that failed, why
the
failure occurred (if known), and any known other details of
the
problem.

E.g., use the same method for each directory-related
property
set during initialization. So if one of those directories
can't
be found, the error message would mention the property name
and
the missing directory path.

    While initializing WikiEngine, could not locate
directory
    '%1' as specified in wiki engine property '%2'.

as in

    While initializing WikiEngine, could not locate
directory
   
'/home/altheim/work/ceryle/resource/webapps/wiki/storage'
    as specified in wiki engine property
   'jspwiki.basicAttachmentProvider.storageDir'.

et cetera. That alone would probably cover many of the
errors we
see with newbies/new installs. Another method for those
properties that expect one of an enumerated list of values,
in
case somebody misspelled something.

Don't know if this is of any help...
