Building the Web Front-End
Step 3 of 11
PortletKeys manage important things like the portlet name or other repeatable,
commonly used variables in one place. This way, if you must change the portlet’s
name, you can do it in one place and then reference it in every class that
needs it. Keys are created in a
PortletKeys class and then referenced in
a component property.
Follow these steps to create your application’s
GuestbookPortletKeysand make sure there’s a public, static, final String called
GUESTBOOKwith a value of
public static final String GUESTBOOK = "com_liferay_docs_guestbook_portlet_GuestbookPortlet";
Save the file.
guestbook-webmodule, open the
GuestbookPortletclass and update the component class metadata properties by adding one new property:
"javax.portlet.name=" + GuestbookPortletKeys.GUESTBOOK,
Note that you need the trailing comma if you’ve added the property to the middle of the list. If you’ve added it to the end of the last, leave it off (but add a trailing comma to the prior property!).
Next, you’ll integrate your application with the back-end you generated with Service Builder.
