Step 4: Create the Action Class

The Welcome portlet has its own action class, WelcomeAction, which provides support for localizing messages. This class extends com.sas.portal.portlet.HTMLPortletAction, which contains code to correctly display non-Latin1 character sets when the portal Web application displays the portlet in preview mode.

The source code for WelcomeAction follows. The box contains explanatory comments. For more information, see Creating Action Classes.
