Problems running example
I'm trying to run the <x:transform> example in the standard-examples web
app, but am having problems with both Tomcat 4.0.2-b2 and Resin 2.1.0.
With Tomcat, I get the following stack trace (this is the start of the root
cause part):
java.lang.NoClassDefFoundError: javax/xml/transform/TransformerException
at java.lang.Class.getMethods0(Native Method)
at java.lang.Class.getDeclaredMethods(Class.java:1039)

I expected that the standard-examples web app would have everything needed
to run the examples, but apparently not. What do I need to add (and where)
to get this to work?
With Resin, I get a different problem:
javax.servlet.jsp.JspException: bad source

.....
Here I have even less idea what's going wrong.
Any ideas, anyone?
Thanks!

Yeah, that's what I had in mind. At least, it's that distribution that
I've tested the JSTL implementation with.

No, loading from the webapp classloader should be sufficient. Just
dropping all the JAXP 1.2 EA2 JARs (barring xsltc.jar) into WEB-INF/lib
should be all you need to do. Let me know if that doesn't work for you,
though. (And keep in mind the Tomcat 4.0.3 bug that prevents it from
working; it's fixed in Tomcat 4.0.4B2.)

Hmm. This is weird. It is, in fact, in the xalan.jar that's in the JSTL Beta
2 distribution, but it's not in the xalan.jar that was bundled into the 4/26
nightly build. A problem with the nightly build process, perhaps?

Sigh. Class loaders bite me again. ;-{

I presume you mean the JAXP 1.2 EA2 that's bundled with the JAX Pack? Also
presumably, I'll need to replace the containers' JAXP implementations with
this, and not just what's in the standard-examples web app?
Thanks, Shawn.

This is just a missing class. In the crimson/xalan pair, it should be
found in xalan.jar; in the JAXP 1.2 arrangement, it's in jaxp-api.jar. If
you use the xalan.jar from the standard-examples.war application, the
right classes should be there; note that not every JAR called 'xalan.jar'
will include it.

This is from a TransformerConfigurationException; as a first guess, it's
related to a behind-the-scenes error casting a class due to conflicts in
the versions between two class loaders.
My best advice is to use the JAXP 1.2 set of JARs consistently; that
should be the easiest way to fix the problem.
