Plugging into Hippo CMS

It's possible to extend the Hippo CMS, via Maven-based Wicket-style applications, as can be seen here:

The Java-side of the Wicket label seen above has this interesting Wicket-oriented code:

add(new Label("label", new LoadableDetachableModel() {
    private static final long serialVersionUID = 1L;
    @Override
    protected Object load() {
        UserSession session = (UserSession) org.apache.wicket.Session.get();
        String name = session.getJcrSession().getUserID();
        DateFormat df = DateFormat.getDateTimeInstance(DateFormat.LONG, DateFormat.MEDIUM, session.getLocale());
        return df.format(new Date()) + " Hallo there "+ name + "!";
    }
}));

After creating the above two Maven-based applications, which I did on the command line via these great instructions, you modify your own CMS in the Hippo CMS console, which looks like this:

Then run your own CMS again, i.e., when you plug in new features, you're creating a CMS on top of the Hippo CMS. The "Hello World" message below (in "fuchsia", as one can read in the first screenshot above) is the result of the new plugin I created:

Next thing is to learn about how to create useful plugins I might want to add to the Hippo CMS. Good to know there are so many examples available here.
