I think <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"; %> is a namespace declaration. With this declaration the namespace prefix is associated with the namespace uri so that the tag processor knows how to handle a JSTL tag when it comes accross it in the JSP page. Namespace prefixes are necessary for a few reasons and one of them is that they allow the processor to distinguish between tags that have the same name but belong to different tag libraries, and having different implementation. For example there can be <c:out value="${myValue}" /> and <x:out select="$abook/title"/> Here , the action - out is distinguished by using the namespace prefixes c or x.

(and the classes are not at this url either..;) hope this question makes sense.. in oreilly (JSP, 3rd ed, ch7) it says the 'uri' attr in taglib directive in JSP is there to find "the class or tag file for each custom action." Then in the very next sentence it says, "the attribute contains a string the container uses to locate the TLD for the library.." but it points to a uri for the classes, right? (or tag files..) not the tld.. (and come to think of it, why is this necessary at all, since the element in the tld always has a reference to the class (like the web.xml for servlets always contains a ref to the servlet class..) and if using tag files like this: ... /WEB-INF/tags/mytags/copyright.tag so, what exactly is the point of the uri and what DOES it point to really? thank you.. -m --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------- Stay in the know.
