PageLink component - Apache

Notice that if you click the “Go back and try again” link, the application reacts properly: it shows the Home page again. But this is more of a coincidence than a proper solution. We left the href attribute empty; this creates a link to the application’s context, and trying to navigate to the context, we land at the default Home page. But in some other case we might wish to go not to the Home page, but to some other page. In that case such a “bare” link would be worthless; we need to use an appropriate Tapestry component.

Let’s define this component implicitly again:

<a rel="nofollow" target="_blank" href = "" jwcid="@PageLink" page="Home">Go back and try again.</a>

The application will continue to work as it did before, but now we have done everything properly, and we can easily redirect the link to some other page by simply changing the name in the page attribute.

As we have defined all three components of the Secret page implicitly, its page specification remains empty, but that’s okay. Later, we might decide to add more components to this page or change its design so that it will make sense to move some components’ definitions to the page specification.

We can congratulate ourselves as we have completed the GuessTheWord application. I didn’t want to delay this glorious moment anymore, so let me leave the discussion of two ways of handling form submission until one of the upcoming parts of the tutorial.

For now, let’s see how to make our completed application available to the outside world, as we have created it not just to play with it on our own computer.
