Well, I'd usually vote for a servlet/JSP page controller setup ;) but I
may be able to help you:
What's the doctype declaration in your web.xml?
You must specify servlet spec 2.4 to have the JSTL functionality you
desire. I don't have the exact syntax on me, but you can find examples
all over the web.

RE: JSTL / MYSQL JDBC / TOMCAT 5
I see that must be where the problem is. I had trouble with the sample
web.xml entries... TOMCAT wouldn't start the DBTest app with the example
as-is, so I commented out the part that caused the immediate heartburn
and that has the 2.4 spec in it.
Here's the extract from the example. Would anyone like to tell me how to
fix it (if I leave it as-is, not only is there no XML tag at the top,
but I get a "XML document structures must start and end within the same
entity." error)? I'll learn it some day, but if I had leisure, I
wouldn't be asking for help...
And if it's really wrong, should someone fix the documentation? Or is it
just not a cut-and-paste candidate?
TIA,
Mark

Long story short: XML tags are like parentheses or curly braces in code;
they must balance.
What you have here is the equivalent of
{
{
}
aka, no closing "}"
Take out the second "" tag.
If you're too short on time to learn XML, invest in a validation tool.
A free one comes with Expat, something like "xmlwf."

RE: JSTL / MYSQL JDBC / TOMCAT 5
I just noticed that this is the syntax given on
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jndi-datasource-examples-how
to.html, complete with the double tags so I wouldn't be surprised
if a number of people run into this problem.

RE: JSTL / MYSQL JDBC / TOMCAT 5
Thanks, that worked. I also appreciate the reference to the XML
validator.
That said, are there any observations about the feasibility of using
Swing for building GUIs to be used via browser? I find too many
unexpected browser peculiarities when trying to do anything too
complicated (probably just me, but...) and would like to use something
more definitively controlled (or more predictable in operation). All my
users will be using MS Internet Explorer, typically v5.5. Googling gives
several old articles on needing plug-ins and the like; any more current
experiences available? If Swing is not practical, how are folks handling
this kind of issue?
TIA...
Mark

RE: JSTL / MYSQL JDBC / TOMCAT 5
Again, I appreciate the feedback. We are working in a rather controlled environment these days and it turns out that the Java plug-in won't go, so the whole applet idea looks to be a non-starter anyway. Live and learn. (or not, I guess...)
