First, let me say thanks for referencing the jsf2-export-pdf-portlet in order to solve your problem. We knew that exporting a resource was going to be a common use-case, so we wanted to develop a demo that was helpful to developers.
Second, I need to point out a bug that we recently fixed in FACES-1891. The "Fix Version" for FACES-1891 is 3.2.5-ga6 so you would need to reference the source code from the 3.2.x branch at GitHub rather than the source code code that accompanies the war file at Maven Central.
Third, I also wanted to point out that the primefaces3-users-portlet also has a resource handler that shows how to display the avatar/image of the selected user. We tried very hard to add meaningful comments to the UserPortraitResource.java and UserPortraitResourceHandler.java source files in order to explain how to use resource handlers correctly.
Please let us know whether or not this information was helpful, so that we know how to improve the demos in order to improve the developer experience.

Thank you for your answers, they helped me a lot.
1) I modified the ResourceHandler as specified in your comment, the Primefaces.js file is now loaded properly.
BUT, I still have troubles with my web components. (<p:datable> pagination not working, <p:panel> toggle not working, etc...)
In the browser console I can see : Uncaught TypeError: undefined is not a function
2) I used the primefaces3-users-portlet to implement a file download fonctionnality but I stiil can't make it work. I have several error line like :
15:22:55,432 ERROR [MissingResourceImpl:78] Resource handler=[com.liferay.faces.bridge.application.ResourceHandlerOuterImpl@ed3e7d9] was unable to create a resource for resourceName=[fichierExportResourceLibrary] libraryName=[null] contentType=[null]
The class ResourceHandlerOuterImpl is not the one I declared into the faces-config.xml
The version I have in ivy.xml for liferay-faces and JSF seem to be OK (I'm using Liferay 6.2) :
<dependency name="jboss-el" org="org.jboss.seam" rev="2.0.0.GA" />
<dependency name="jsf-api" org="com.sun.faces" rev="2.1.27" />
