I think the REQUEST TIME EVALUATION for custom taglibs is broken in as
TOMCAT 3.2.1. I could not get my Custom Tag to work. In the end I found
that using apparently simple custom tags to many times would produce
wait for it
JSP CODE BLOAT.
I had one post compiled JSP in $TOMCAT_HOME/work/*/*.jsp that was over 200K
in size. You would not write a single Java Servlet that is 200K long. That is
because use a simple tags such this
(1)
<img src="<foo:contextPath/>/image/help.gif"
width="24" height="24" border="0"
alt="Get Help for this web page!" >
whereas before I had
(2)
<% String contextPath = request.getContextPath() %>
<img src="<%= contextPath+"/image/help.gif" %>"
width="24" height="24" border="0"
alt="Get Help for this web page!" >
Compare the two post compiled java file in Tomcat.
So moral of the story: Custom tags are great for complicated and
business logic tasks. Custom tags are bad for repetitious and
seamingly simple tasks for example just for a `readable-win-win'.
BTW: May be RESIN implements JSP 1.2 other I dunno what server does

Subject: JSP 1.2 ?
Hi,
I would like to do a such things using the jakarta tagllibs :
<% String connName = application.getAttribute("AName"); %>
<sql:connection id="<%= connName %>" >
...
</sql:connection
It seems possible with the specification JSP 1.2 .
Is there another server than TOMCAT 4.n which implements this specificaiton
?
