Re: It's late and I'm feeling stupid
Another day, and I start it out much more alert and perceptive.
Unfortunately I'm still not seeing the solution. (Undoubtedly I am ignorant
of some key piece of struts knowledge that is holding me back. :-)
I see how struts-el would allow me to reference ${foo} values within the
html-el:link tag, but that isn't the problem. The field of the html:link
tag that I want to use only takes references to beans, so I have to get my
value into a dynamically declared bean first.
I don't think struts-el tags will help with this - at least not this step in
the problem. Or am I missing something?
Any other suggestions?

So here is my vague ans. Use Struts-el tag lib, it works well with JSTL

Re: It's late and I'm feeling stupid
From http://jakarta.apache.org/struts/userGuide/struts-bean.html#define
The bean:define tag differs from jsp:useBean in several ways,
including:
* Unconditionally creates (or replaces) a bean under the specified
identifier.
* Can create a bean with the value returned by a property getter of
a different bean (including properties referenced with a nested
and/or indexed property name).
* Can create a bean whose contents is a literal string (or the
result of a runtime expression) specified by the value attribute.

it in the morning.
Any suggestions?

Re: It's late and I'm feeling stupid
Jeff, I tried to look at your original post and I dont really understand the
exact problem.
You post your minimal code and see if I can help.

Try using c:url and c:param to build up a url with parameters, then
reference the ${url} variable from the href attribute of html:link.

Yes Jeff / David this works for me
David Try using c:url and c:param to build up a url with
parameters, then
David reference the ${url} variable from the href attribute of
html:link.
c:url value=userPg var=url
c:param name=ID value=${item['id']}/
c:param name=Dispatch value=Zoom/
/c:url
a href='c:out value=${url}/'[Zoom...]/a
ending up with the following displayed in the JSP
[Zoom...]
with the following link / URL properties
http://localhost/do/userPg?ID=22Dispatch=Zoom
will open in the same window

Re: It's late and I'm feeling stupid
That will work, but it has a built-in weakness. It side-steps the struts
action mappings by hard-coding the destination URL in the JSP.
The approach that I was using last night (which James helped me solve this
morning) was to go this way:
bean:define id=myBeanName
c:out value=${myXMLValue}/
/bean:define
html:link forward=MyActionForwardName paramId=myParamName
paramName=myBeanName/
That constructs the proper link reference:
http://localhost/MyAppName/MyActionForward.do?myParamName=myXMLValue
And it still works if I change the declaration of MyActionForwardName in
struts-config.xml
