I can't get TLD auto discovery to work for any custom taglibs i write
when I package them as jars. It works fine for the standard taglibs
(core, fmt, etc..). The tld file is packaged inside the jar as
'/meta-inf/breadcrumbs_1_0.tld', and breadcrumbs-1.0.jar is located in
/WEB-INF/lib. If i put a copy of the tld in the WEB-INF directory and
add a <taglib/> entry for it in web.xml, I'm able to use the tags. I
don't understand why Tomcat (5.0.28) is auto detecting the TLD files
inside the standard taglibs (standard.jar), but it won't autodetect them
in jar files i produce. Any help would be greatly appreciated.
