I’ve a JSP with

<%@taglib uri="http://java.sun.com/jsf/facelets" prefix="ui" %>

However it errors with

The absolute uri: http://java.sun.com/jsf/facelets cannot be resolved in either web.xml or the jar files deployed with this application

I have libraries facelets-lib.jar and jsf-facelets-1.1.10.jar, which I suppose is Facelets, but they do not contain JSP taglib descriptors.

What file is correct?

    Facelets is intented to replace JSP altogether. But yet you’re attempting to declare it as a JSP taglib. This is never going to work. Both are distinct view technologies. Facelets is a XML based view technology which is designed to be a successor of JSP. In Java EE 6 which was released december 2009 it has already replaced JSP as standard view technology for JSF and JSP has since then been deprecated.

    You need to rename file extension from .jsp to .xhtml and replace all JSP taglib declarations by XML namespace declarations and remove all <jsp:xxx> tags and all <% %> scriptlets.

    So, for example the following basic JSP template page.jsp

    <%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<!DOCTYPE html>
<f:view>
    <html lang="en">
        <head>
            <title>JSP page</title>
        </head>
        <body>
            <h:outputText value="JSF components here." />
        </body>
    </html>
</f:view>

    has to be rewritten as page.xhtml

    <!DOCTYPE html>
<html lang="en"
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:ui="http://java.sun.com/jsf/facelets">
    <head>
        <title>Facelet page</title>
    </head>
    <body>
        <h:outputText value="JSF components here." />
    </body>  
</html>

    Finally, the mentioned JAR files are Facelets 1.x JARs while Facelets 2.x is already been out since 2009 as part of a JSF 2.x implementation. If you can, I’d strongly recommend to just skip Facelets 1.x and continue with Facelets 2.x.
