RE: Tag Libraries in host other than the main server.

Well I checked the file names, and they are fine. Then to make sure it
was finding them I changed the path in web.xml to look for my file (to
see what error I would get), and this tells me that it was finding the
tld fine before keying in an invalid path.

I know the class will be loaded into memory by the way my jar files are
in my lib directory for the application. Does anyone else have tag
libraries running from a Host other than localhost? Localhost is
usually the default host. I have another host defined called
www.cltractor.com and am using that host to try to use tag libs. I
think I might like to get into the tomcat code to try to locate some of
the issues. But, I'm going to be a newby to that code. Any help is
appreciated.

I'm running on Linux using Sun JDK 1.4.1_02. Everything else other than
Alias and this seems to be working fine.

Thanks again,

Wade

 Check WEB-INF directory to see if its name is in the same way as
web.xml, because its case-sensitive.
