JSF on Google App Engine with Facelets

Having tried JSF on Google Java App Engine, how about Facelets and JSF?

Works OK with MyFaces 1.1, see here for a test.

    The code is beyond simple :)

    package com.softwyer.gapp.jsf;

    import java.io.Serializable;
    import java.util.logging.Logger;

    public class TestHandler implements Serializable {

    private static final Logger logger = Logger.getLogger(TestHandler.class
    .getName());

    /**
    *
    */
    private static final long serialVersionUID = 3844698105980368981L;

    private String name = null;

    public TestHandler() {
    logger.info("Constructor initiated");
    }

    public void setName(String newName) {
    name = newName;
    }

    public String getName() {
    return name;
    }

    public boolean isRendered() {
    boolean rendered = name != null && !("".equals(name));
    logger.info("Checking rendered state for name: <" + name
    + ">. State is: <" + rendered + ">");
    return rendered;
    }

    public String buttonClicked() {
    logger.info("Button was clicked");
    return "";
    }
    }
