I don't think option 5 is right. I tested the following scenario. It works perfectly.

1. I defined a s simpel tag and placed in WEB-INF/classes directory.
2. Built a jar file mylib.jar and placed the TLD named taglib.tld in the META-INF directory of the jar file.
3. In JSP, i declared <%@ taglib prefix="mytag" uri="WEB-INF/lib/mylib..jar" %>

Does anybody have any definite answer? I am confused too.
