No, actually you don't have to in Tomcat 5. It does ship with JSTL
built in. You just have to use the appropriate declarations in the
web.xml and so on.

What do you mean when you say that Tomcat 5 implements JSTL "natively"?
From my experience, Tomcat 5 does not ship with JSTL. You must
download
and install JSTL separately.

Subject: RE: passing JSTL to custom tag attribute
I would say there are several basic ideas here:
1. Use a JSP 2.0 container, like Tomcat 5. The JSTL is implemented
natively there.
2. Use solution 1.
3. Build a second tag library that's implemented exactly like
Struts-EL.
Each tag class in Struts-EL is a subclass of the corresponding tag in
the base library, and the only functionality in the Struts-EL tag is to
pass the attribute value through the EL engine from the Jakarta JSTL
implementation.
4. Do not build a tag library that implements your business logic AND
references the Jakarta EL engine. When you move to a JSP 2.0
container,
you'll then have to spend more time yanking it out.

Subject: passing JSTL to custom tag attribute
Hi,
I wish to call a custom tag, passing a dynamic value for
its attribute. I retrieve the value thus:
<c:set var="userid" value="${param.userid}"/>
and I wish to call my custom tag passing 'userid' as an
attribute. Curently I have:
<my:execute userid="${userid}">
but the literal string "${userid}" is passed into the
handler. To acheive the desired results I could of course use:
<my:execute userid="<%= request.getParameter("userid") %>">
but that would mean embedding JSP, when I wish to encompass
all logic in tags. Does anyone have any suggestions how I
might pass the JSTL value, dynamically to the attribute of my
custom tag please?
Thanks
Paul.
