I've been following this discussion and find your example below interesting.
I've also been reading about tab librarys and just downloaded JRun's most
recent one (ships with JRun 3.0 CR1). The library isn't tied to JRun
specifically, but there's a feature that might help out with this. I haven't
actually used the library, but from reading the docs perhaps it'll help. Let
me explain.
The example again...

> 4.- The JSP you would like to produce would be something like..
Assuming you have customer.xml (#1 above) and customer.xsl (#3 above) as
files in the same directory, you could use the xslt tag to perform the XSL
transformation of the xml. The syntax would be:
<%@ taglib uri="/WEB-INF/taglib.tld" prefix="stl" %>
<stl:xslt xml="customer.xml" xsl="customer.xsl"/>
If customer.xml was dynamically produced, you could use this alternative
syntax:
<stl:xslt xsl="customer.xsl">
<Customer Name="John Doe">
<Account ID="01" Balance="1230$">
<Account ID="02" Balance="-50$">
</Customer>
</stl:xslt>
There's other tags/tools for getting ResultSets into XML documents that
could produce the above code, but that's another topic :-). Since all of
your display logic and format are in the xsl file, there's no need to redo
these in the JSP. Changing of logic would require a change to your xsl file
but not your JSP file, since it's just putting the xml on the page.
Might this be a viable option?
