Where did http://jakarta.apache.org/struts/tags-tiles go?

I am working through some co开发者_如何学Pythonurse material from Sun (now oracle) to learn something new (Web-Services to be precise). And it is lesson one and when running the example web page I am greeted with:

org.apache.jasper.JasperException: /WEB-INF/pages/layout.jsp(3,74) PWC6188: The absolute uri: http://jakarta.apache.org/struts/tags-tiles cannot be resolved in either web.xml or the jar files deployed with this application

I located the problematic line:

<%@taglib uri="http://jakarta.apache.org/struts/tags-tiles" prefix="tiles"%> 

And now I am at a loss. And I know Sun should provide better example. But can anybody help me?

That taglib was actually part of Apache Struts. You need to install it in order to get those taglibs to work (just download the JARs and drop them in /WEB-INF/lib). However, Tiles grew up out of Struts and became independent almost a decade back. See also their homepage.

Tiles grew in popularity as a component of the popular Struts framework. It has since been extracted from Struts and is now integrated with various frameworks, such as Struts 2 and Shale .

Read up-to-date tutorials about webservices ;) Start with Tiles docs if you want to keep using Tiles for some reason. The new taglib URI is

<%@ taglib uri="http://tiles.apache.org/tags-tiles" prefix="tiles" %>
