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.
