#13371 — Validate or unit test for TLD files?

We have a tag lib descriptor file, and when we tried to integrate it we 
found a problem.  Is there an easy way to validate and/or unit test a 
TLD file?

Thanks,
Daniel.

I presume you mean a file like this?

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag
Library 1.1//EN"
"http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd">
<taglib>
 <tlibversion>1.0</tlibversion>
 <jspversion>1.1</jspversion>
 <shortname>j2eeforum</shortname>
 <info>Sample Tag library  Created for j2eeforum </info>
  <!-Tag Starts -->
  <tag>
    <name>ipaddress</name>
    <tagclass>j2eeforum.IpAddress </tagclass>
    <bodycontent>empty</bodycontent>
    <info>
 This is a example tag for displaying ipaddress.
    </info>
    <attribute>
    <name>target</name>
    <required>false</required>
    <rtexprvalue>true</rtexprvalue>
     </attribute>
</tag>
</taglib>

You could feed an example into Stylus Studio and it will generate you
an XSD for it. Polish the XSD manually, and you have a syntax checker.

Syntax is one thing, but not the only thing that contributes to 
validity.  Classes need to be spelled correctly, functions need to have 
the correct signatures, etc...

One Google web search later....

And... that doesn't provide any build-time validation.  Thanks, but I 
use google myself. The answer wasn't forthcoming so that's why I asked here.

If possible, I'd like to validate these outside of having a J2EE 
container running.

What kind of errors won't show up by just using the TLD? 
Surely you are not the first person to encounter this problem.

That's the problem, I want to find the errors before use. This is in a 
library package separated from its uses.

I think (repeated) app deployments in a container _will_ winkle out all
the problems. That's been my experience. But it is quite time-consuming,
which is what I think Daniel is getting at.

What I do for Facelets taglib descriptor files *and* the XHTML pages
that use them - which are the only variant I am interested in - is run a
few scripts I've written myself. It's not particularly complicated bash
or Windows Powershell logic.

On a related note I've found myself doing similar things for validating
persistence.xml config files.

I can not see any other way than writing a unit test JSP
page, deploy it and TLD+JAR and then unit test the output
from the JSP page.

It is very debatable whether that is really *unit* testing,
but ...
