Problem with PrimeFaces taglib in using JSF

Question

I downloaded and added primefaces-3.0.M1.jar file to my project.
Then, I added this code to my JSP page:

<%@ taglib uri="http://primefaces.prime.com.tr/ui" prefix="p" %>

But it gives the error:

Can not find the tag library descriptor for "http://primefaces.prime.com.tr/ui"

Can anyone guide me how to overcome this problem?

The taglib descriptor looks fine. Where did you put the jar file? — Matt Handy, Apr 13 '11 at 07:24
i added jar file in Build Path as external Archive, i also check by adding jar file in lib folder under web-inf — sadia, Apr 13 '11 at 07:30

In the primefaces forum there are some comments that Primefaces 2.x and above won't work with JSP. Use Facelets instead.

A facelet page using primefaces looks like this:

    <?xml version='1.0' encoding='UTF-8' ?> 
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml"
          xmlns:ui="http://java.sun.com/jsf/facelets"
          xmlns:h="http://java.sun.com/jsf/html"
          xmlns:f="http://java.sun.com/jsf/core"
          xmlns:p="http://primefaces.prime.com.tr/ui">
      <h:head>
        ... put your header info here
      </h:ead>
      <h:body>
        .. put your content here
      </h:body>
    </html>

There are some more things to pay attention to if you want to switch from jsp to facelets. I think you start reading some tutorials or this related question and answers.

On glassfish3 facelets must have a .xhtml not .html extension to be recognized as those. — Sebastian Hoffmann, Jul 11 '12 at 13:03

That is true IF you are already using the correct namespace. In this case the namespace was wrong. – Kukeltje Feb 17 '16 at 11:31
i had the same problem with correct namespace. after i've added primefaces into the buildpath i was able to use p: tag library... – vc.0 Feb 17 '16 at 11:33
Yes, that is what I said.. IF you already use the right namespace and you get this error, then this is the answer. But that is **not** what the problem in this question is about. So please add a clarification in the answer. And add info about version etc – Kukeltje Feb 17 '16 at 12:38

You could try the following workaround:

<% response.setContentType("application/xhtml+xml"); %>

1) Doesn't solve the problem at all. 2) MSIE browser doesn't support this content type and will then pop a *Save As* dialogue. – BalusC May 01 '12 at 19:27
