How Create Custom Mode in Portlets

How Create Custom Mode in Portlets

Step :01 → First of all you need to configure mode  in your portlet.xml file

<custom-portlet-mode>

<portlet-mode>custommode</portlet-mode>

</custom-portlet-mode>

Step :02 →Instantiate with in your Portlet  by passing  mode name in PortletMode class and make this variable as final .

private static final PortletMode CUSTOM_MODE = new PortletMode("custommode");

Step :03 → Define the Method that you want to Execute  for this Mode

protected void doCustomMode(RenderRequest request, RenderResponse response) throws PortletException, IOException {

// Set the MIME type for the render response

response.setContentType(request.getResponseContentType());

// Invoke the JSP to render

PortletRequestDispatcher rd = getPortletContext().getRequestDispatcher(getJspFilePath(request, CONFIG_JSP));

rd.include(request,response);

}

 

Step:04 -->Overrides the doDispacher method of the GenericPortlet

/**

* Override doDispatch method for handling custom portlet modes.

*

* @see javax.portlet.GenericPortlet#doDispatch(javax.portlet.RenderRequest, javax.portlet.RenderResponse)

*/

protected void doDispatch(RenderRequest request, RenderResponse response) throws PortletException, IOException {

if (!WindowState.MINIMIZED.equals(request.getWindowState())){

PortletMode mode = request.getPortletMode();

if (CUSTOM_MODE.equals(mode)) {

doCustomMode(request, response);

return;

}

}

super.doDispatch(request, response);

}
