Newbie - JSF question

zalek · Jul 28, 2008

I am learning about JSF from the site http://exadel.com/tutorial/jsf/jsftutorial-kickstart.html
There is an example of JSP program:
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
<f:loadBundle basename="jsfks.bundle.messages" var="msg"/>

<html>
<head>
<title>enter your name page</title>
</head>
<body>
<f:view>
<h1>
<h

utputText value="#{msg.inputname_header}"/>
</h1>
<h:form id="helloForm">
<h

utputText value="#{msg.prompt}"/>
<h:inputText value="#{personBean.personName}" />
<h:commandButton action="greeting" value="#{msg.button_text}" />
</h:form>
</f:view>
</body>
</html>

When I try to run it I am getting:

exception

org.apache.jasper.JasperException: This absolute uri (http://
java.sun.com/jsf/html) cannot be resolved in either web.xml or the jar
files deployed with this application

I checked web.xml - there is no reference to any http://java.sun.com/jsf/html.
Any ideas what is a problem?

Thanks,

Zalek

Right. I'm just guessing, but the error is that it can't find the URI
in the web.xml. It's saying you need to add one. IIRC, the URI needs
to point to a taglib with the JSF tags in it.

Here's a bit more info that I've dug up. There's two ways of specifying
a taglib file. First, in J2EE 1.x, you need to add a <taglib> element
in your web.xml.

<web-app>
<jsp-config>
<taglib>
<taglib-uri>http://java.sun.com/whatever</taglib-uri>
<taglib-location>/WEB-INF/myStuff.tld</taglib-location>
</taglib>
</jsp-config>
//... etc

That's what you're missing. You need the .tld for JSF too, which is
probably hiding inside the jsf-impl.jar file.

If you are using Java EE 2.0, then you don't need the <taglib> element.
The server will just magically look in several places in your /WEB-INF
directory. The easiest is just the root (/WEB-INF/myStuff.tld) so you
can make sure the .tld gets put there.

The tutorial is probably assuming a 2.0 spec, which needs no <taglib>
and you have 1.x, which requires one. Hence the error. That's my best
guess.
