I just downloaded the standard tag library RC1 newly posted by Shawn which
is supposed to be the same as the 1.0 release. I noticed that the XML
parser has been changed from Xerces to Crimson, and wonder if this is what
is causing the following exception. I am running with the also newly posted
Tomcat 4.0.4 final release, on Windows 2000, with JDK 1.3.1_03. When I run
the included examples WAR, and go to the XML transform example, I receive
the following stack trace. Any advice on how to fix this is appreciated.
(Curiously, the version of JSTL included in Sun's jwsdp-1_0 download was
still using Xerces, so the two are not quite equivalent) Thanks, --Loren
