In the JGameStore application, the index() method of the CatalogBean makes a
call to the CatalogService to populate a List of the newest products from each
category. Since we provide a better example of this bit later, we won't explain it
here. At this point, we'll just accept that the index() method returns a success
String and is forwarded to the first page in the cart (see listing 14.5).

Listing 14.5 index() method of catalogBean

public String index() {
…
return SUCCESS;
}

Next, we can use our index.jsp to successfully forward to the main page through
the Struts controller. There is nothing to the index.jsp except a forward. Be sure
to specify the .shtml extension on your forward URL so that your servlet container
will route the request through the Struts controller (see listing 14.6).

Listing 14.6 JSP forward

<jsp:forward page="/index.shtml"/>

Next, you'll learn how to set up a presentation bean and create a behavior
method that can be called.

14.6.2 Utilizing a presentation bean

When visitors arrive at the cart, they select a category they wish to examine. Our
next step is to capture the category and display a listing of products on a subse-
quent page. To achieve this, we need to create the following:

A tiles definition in our tiles-defs.xml

■

Our Category domain object (see listing 14.7)

■

Our Product domain object (see listing 14.8)
