I have developed a lot of custom tags (or custom "actions" to use the JSP spec
language), first an upgrade of our InstantOnline Basic component suite
(see http://www.gefionsoftware.com/InstantOnline/) and a set tags for a book
I'm writing.
Custom actions are really powerful and let you avoid almost all code from
your pages. I've found that in some cases, small JSP expressions as run-time
attribute values are still needed, and even more attractive than using
<jsp:getProperty> even when they are not strictly required. I also use scriptlets
for simple conditions, such as
<% if (someCondition) { %>
do something with template text and actions
<% } %>
Sure, you could make your own <myLib:if> action, but to me it doesn't make
the page easier to develop or understand for non-programmers.

I use the Jakarta Tomcat server, see http://jakarta.apache.org for this development.
I'm not familiar with SJSP, but extending the "JSP TLD" doesn't sound like it's
the way to do it. If you develop your own custom action library you need to
create your own TLD to describe the tags.
