I dont know how good JSPTL is because its dependant on Tomcat 4 (and/or JSP
1.2) and thats where the problem lies - we are using Tomcat 3 so I haven't
looked at it. When Nivarna comes and JSPTL is part of the JSP spec (1.3
perhaps?) and everyones using servlet containers that support it then this
stuff is redundant.
The question is, when is that going to be and whats the best thing to do in
the meantime for a) people using JSP 1.1 and b) people using JSP 1.2?
My tags also included a switch/case/default which is equivalent to the
choose/when/otherwise pattern in JSPTL and the if/else also supports
and/or/elseif tags.
I could re-engineer the if/else/elseif to not need a then and I believe
this would make them as elegant as they could be. However its not worth it
if theres no enthusiasm for the tags and everyones either switching to JSPTL
or happy to go with whats already there (scriptlet or the current logics
tags) until they switch to JSPTL.

I agree with this. In particular, I'd like to see tags of this type
incorporated in JSPTL. They currently have if, and
choose/when/otherwise, but no explicit then or else
(although I
believe those can be constructed from the others).
The if/then/else pattern can indeed be constructed from
choose/when/otherwise tags in JSPTL.
The reason that Struts never had an else tag in the first place is that
the syntax choices were all incredibly ugly, IMHO, given the restrictions
on the way you need to nest things to make it work. The
choose/when/otherwise pattern in JSPTL is the least objectionable, and has
the additional advantage of gracefully implementing if ... else if ...
else if ... type patterns as well.
Given that choose/when/otherwise does this (and more), I would be somewhat
surprised if the JSPTL expert group was willing to consider adding
explicit if/then/else tags as well (because they would be redundant). But
the best way to find that out would be to provide feedback on the JSPTL
early access release (available via http://jakarta.apache.org/taglibs)
to the email address included in the docs.

My take on this is here
http://www.mail-archive.com/struts-user@jakarta.apache.org/msg14158.html
I'm personally not in favor of distributing tags with Struts
that do not
depend on Struts application resoures (mappings, messages). General
purpose tags can be hosted at Jakarta Taglibs. At some point,
the Struts
bean and logic tags will end up over there too.
If someone wanted to re-package the Struts logic tags for Jarkarta
Taglibs, and included Nial's extensions, I'm sure they would be well
received. Ditto for the bean tags. They already have i18n and
form tags
that are similar to the Struts versions.
