Because the SampleWelcome portlet does not need its own initializer class, the default portlet initializer (JspPortletInitializer) is specified. This class requires a parameter named display-page. The initializer places the value of this parameter in the PortletContext object so that it can be used by the portlet's action class. The value of the parameter is the name of the SampleWelcome portlet's JSP page, named Welcome.jsp. Note:   The default initializer passes only the display-page parameter. To pass additional parameters, you need to create your own initializer class. For more information, see Creating an Initializer Action Class.
