Re: Taglib packaging of struts.jar!META-INF/tlds/*.tld not spec-compl iant?

Hi David,

Putting multiple TLDs in the META-INF/tlds subdirectory is a JSP 1.2
thing, which won't be recognized by a JSP 1.1 container.  For the upcoming
Struts 1.1-beta2 release, we're still doing that (for the convenience of
those running on 1.2 containers), but are *not* including a
META-INF/taglib.tld file -- JSP 1.1 users will need to package the TLDs
separately in the WEB-INF subdirectory, and declare them in web.xml (as
the struts-example webapp does).
