JSF tags not rendering - FacesServlet not working maybe?

Tags:

I am just getting started with JSF 2.0 and I'm stuck on a problem at the very beginning. JSF tags are not parsed.

Below are some details. Hope someone can help because none of the related SO questions have been able to solve my problem.

hello.jsp

<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:p="http://primefaces.org/ui">

    <h:head>

    </h:head>

    <h:body>
    <f:view>
        asd
        <h:inputText value="asd" label="UserName"></h:inputText>
    </f:view>
    </h:body>
</html>

What I see when I navigate to http://localhost:8080/JSFDeneme/pages/hello.jsp

Only the plaintext asd

View source of http://localhost:8080/JSFDeneme/pages/hello.jsp

Exactly the same as the contents of hello.jsp

<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:p="http://primefaces.org/ui">

    <h:head>    
    </h:head>    
    <h:body>
    <f:view>asd
        <h:inputText value="asd" label="UserName"></h:inputText>
        </f:view>

What I have in WEB-INF/lib

  • JSF 2.0 (Apache Myfaces JSF Core-2.0 API 2.0.2) - Eclipse downloaded that
  • jstl-api-1.2.jar
  • jstl-impl-1.2.jar
  • primefaces-3.0 jars

What Tomcat prints to console when I restart the server and navigate to the page

There seems nothing odd and no mention of FacesServlet?

hello.jsp

This is not the right extension.

Since JSF 2.0, JSP is deprecated and replaced by Facelets. Facelets is a XML based view technology and supposed to be written in .xhtml files. However, you seem to already have used valid Facelets syntax in your JSP file. All you need to do is to just rename hello.jsp to hello.xhtml.

I also recommend to replace all URL patterns by a single URL pattern *.xhtml.

<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.xhtml</url-pattern>
</servlet-mapping>

so that you can open it by http://localhost:8080/JSFDeneme/hello.xhtml without fiddling with virtual URLs.

I'm not sure what books/tutorials you've read which made you to use the JSP extension. Perhaps you were reading a mix of JSF 1.x and JSF 2.x targeted tutorials. You need to make sure that you're reading JSF 2.x specific tutorials. At the bottom of our JSF wiki page you can find several JSF 2.x tutorial links.

I guess that, as you are invoking a .jsp URL you are rendering the page via the good old JSP servlet (you have the /pages/* URL mapped to the Faces servlet, but JSP extension mapping might be taking precedence).

Can you try renaming your page to a .jsf and invoking that?
