[TAGLIB] No such tag XXX the tag library imported with prefix XXX
I am using the book "Web Development with JavaServer Pages" to develop a tag
library for my company. I've created the TDL file describing the tag, and the
Java tag handler class. I've got a page referencing the TDL, and then the page
uses the tag defined in the TDL. But, I get the error:
No such tag task the tag library imported with prefix sched
where "task" is my tag name, and "sched" is the prefix.
I've tried all mixes of capitalization, so I don't think it has to do with
that. I am using Tomcat as my web server, running locally on a Win98 machine,
and am running JDK 1.1.8_3.
Has anyone experienced this problem before. If so, any solutions?
I'm including my source below, in case that helps.
Thanks!

Re: [TAGLIB] No such tag XXX the tag library imported with prefix XXX
from my exp,I think you should check the the location of your taglib class
file.for tomcat I think you just put it in classes dir and check your
web.xml,make it correct.

Re: [TAGLIB] No such tag XXX the tag library imported with prefix XXX
Thanks for the response. The culprit ended up being the text that I was copying
from to create my TDL file. It was pointing to an invalid DTD address.
