To provide for internationalization of the text that appears inside the portlet border, the SampleWelcome portlet has its own action class, named WelcomeAction. The name of the class is specified in the <type> subelement of the <portlet-action> element.

      <portlet-actions>
         <portlet-action name="display" default="true">
            <type>sample.welcome.WelcomeAction</type>
         </portlet-action>
      </portlet-actions>

   </local-portlet>
