I use XSP mostly for control. Taglibs are nice to encapsulate things with, but
when you encapsulate the control flow of your program, things often get
difficult as soon as you need that functionality again, but a tiny little bit
different. So I usually end up with building blocks below the "Control" level
which I then put together in an XSP page.
compare this:
<mytaglib:form-or-result/>
with this:
if (<mytaglib:is-query-complete/>) {
<h1>Congratulations, you have completed the form!</h1>
} else {
<mytaglib:show-form/>
}
the latter is more typing, but lets you control what happens when the query is
complete or not - maybe you want to redirect him to a help page on the third
miss, but only on this form and not on others, and so on.
