This week's book giveaway is in the OCMJEA forum. We're giving away four copies of OCM Java EE 6 Enterprise Architect Exam Guide and have Paul Allen & Joseph Bambara on-line! See this thread for details.
JSP.7.2.1 Packaged Tag Libraries . . Packaged tag libraries must have at least one tag library descriptor file. The JSP 1.1 specification allowed only a single TLD, in META-INF/taglib.tld, but as of JSP 1.2 multiple tag libraries are allowed. See Section JSP.7.3.1 for how TLDs are identified. . .
When I specify <taglib> <taglib-uri>http://java.sun.com/jsp/jstl/core</taglib-uri> <taglib-location>lib/appserv-jstl.jar</taglib-location> </taglib> in web.xml, I am getting error about not being able to find taglib.tld. When I comment <taglib> element out, the application works fine. I check appserv-jstl.jar, there is no taglib.tld anywhere under META-INF, all they have are c.tld, fmt.tld,.. etc.
1. So why does the book (which is meant for JSP 1.2), it has to be taglib.tld while the JSP spec says that is only for JSP 1.1 ?
2. From my experience, it seems that when you define explicit mapping in deployment descriptor, the jsp container is looking for taglib.tld, when in implicit mapping (without <taglib> defined in web.xml), the jsp container reads all .tld under META-INF folder in the packaged jar files. Is my assumption right?
