In the study too kit book , on page 287 the paragraph "Understanding explicit mapping" says
� <taglib-uri>. This is the user-defined URI. Its value can be an absolute URI, a root-relative URI, or a non-root relative URI. � <taglib-location>. This is the TLD resource path. Its value can be either a root-relative URI or a non-root relative URI, and it must point to a valid TLD resource path.
but in the uri tag i think u can just use any words u like . has any body tried ?
