Are your referencing your tag in jsp by code likes:
<%@ taglib prefix="display" uri="http://displaytag.sf.net"; %>
I am not sure, but maybe in the old version of JSP specification, you
need add this to your web.xml:
<taglib>
<taglib-uri>http://displaytag.sf.net</taglib-uri>
<taglib-location>/WEB-INF/tlds/displaytag.tld</taglib-location>
</taglib>
to tell the app server where to locate the tld file.
And also, you need extract the [displaytag.tld] file
from the source or jar of [displaytag] (under the [META-INF] folder),
and put it to the right folder.
In new version of JSP specification, the tld file can describe itself,
and the app server can find it under the [META-INF] folder(of JAR
file) automatically. You don't need to configure it in the web.xml.
That's why your taglib works in tomcat 6.0 which implements the JSP
specification 2.1,
but not in tomcat 4.1 which implements JSP specification 1.2.
