I’ve been struggling on an issue for days and I don’t know what to do to have it work.
I try to use Tomahawk components that works with javascript… And I always get a javascript error : “xxx is not defined” (xxx=orgApacheMyfacesPopup for instance).

As far as I know it seems to be an extension filter issue : the server can’t serve the .js containing the needed definitions… But I can’t see what’s wrong.

I’ve just done a little project with eclipse from scratch and I always get the error.

The steps I followed were :

  1. create a new Web Application Project (targetting Tomcat 6, adding support for JSF2.0 downloading Myfaces2)
  2. Download and copy jsstl-api-1.2.jar and jstl-impl-1.2.jar to WEB-INF/lib
  3. Download Tomahawk for JSF2 and copy the jars to WEB-INF/lib
  4. Modify web.xml (as delivered after)
  5. Create index.xhtml (as delivered after)

My web.xml :

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">

                        displayAtDistanceY="0"
                        >

                <f:facet name="popup">
                    <h:panelGroup>
                        <h:outputText     value="foo"/>
                    </h:panelGroup>
                </f:facet>
            </t:popup>
        </h:form>
    </body>
</html>

Does anyone ansderstand why it doesn’t work ?

PS : I tried with Tomecat 7 and it doesn’t work better…

Thanks

Nobody ?
Has anybody make Myfaces2 and tomahawk2 work with javascript and xhtml ?
Do somebody know where to find samples for it ?
Samples on MyFaces website seem to target JSF 1.1 and JSP-like pages…

    You need a <h:head> instead of <head> in order to auto-include JavaScript (and CSS) files which are specific to JSF components. Additionally, you should preferably also replace <body> by <h:body>.

    The proper Facelet template should look like this:

    <!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"
    xmlns:t="http://myfaces.apache.org/tomahawk">
    <h:head>
        <title>Title</title>
    </h:head>
    <h:body>
        <h1>Body</h1>
    </h:body>
</html>
