This is the home page of the Tapestry Hotel Booking demonstration app. This page is constructed by Tapestry using an HTML-formatted template file, Index.tml. The small amount of code supporting this page is in the correspondingly-named class file, Index.java. Generally, every Tapestry page has a template file and a class file sharing the same name.
The overall layout of all pages in the app (the common header and footer elements, for example) is controlled by the Layout.tml template. This page (like most of the others) explicitly wraps itself in the Layout component by specifying <html t:type="layout".../> at the top of its template file.
The <t:zone> component in this page's template file (Index.tml) surrounds the HTML elements for the layout of content within the zone. In this case, those HTML elements consist of an HTML table produced by Tapestry's built-in Grid component (which only appears when there are search results to display).
Also, we're using the Grid component's built-in partial refresh option ("inPlace") that allows pagination and sorting to occur without redrawing the whole page.
Finally, the "Details" link in each row is built with Tapestry's PageLink component, which in this case constructs a URL that includes an "activation context" (the part of the URL after the page name) consisting of the primary key of the record in the database corresponding to each table row.
