If you want to use constant fields, check out the archives for this
list...There have been some good posts in the last couple of weeks on how
to accomplish this...JSTL does not provide a mechanism for retrieving
constant values from classes...Of course, there is a tag for it in the
unstandard library...But something about an unstandard library as part of
a standard library just gives me a headache...So, I would stay away from
that and use solutions based on the J2EE spec...

Since you're using Struts, the application resources file is a good place
to stick constant values as well...
