Custom Portlet modes

[siva prakash]

Hi All,


I am new to portlets and going through specification v1.0 for my new project. In section PLT.8.4 Custom Portlet Modes was mentioned. I have doubts about this new modes. when a developer goes for this in real time and how to map to vendor custom modes.

any help in this regard is appreciated, thanks in advance


With Regards,

About? Print? Config? All great ideas for custom portlet modes.

The point is, a custom mode is only possible if the vendor supports it. For example, IBM provides a config mode, and their portal supports it. So, I can create a portlet that uses a config mode, and deploy it to WebSphere Portal, and life is grand. But, if I deploy it to Pluto, well, it simply won't work as designed.

I put together a tutorial on creating custom portlet modes. It deploys a custom portlet to WebSphere Portal Server 5.1. Enjoy:

It's a good idea. It allows vendor flexibility and competition, but also maintains compatability across portals. Custom mode or not, all portlets must have a view mode.

   
/**
*
* A sample portlet based on GenericPortlet
*
*/
public class CustomModePortlet extends GenericPortlet {
 
/**
* @see javax.portlet.GenericPortlet#doView(RenderRequest, RenderResponse)
*/
protected void doView(RenderRequest request, RenderResponse response) throws PortletException, IOException {
response.setContentType(request.getResponseContentType());
response.getWriter().println("Hello WOrld From Cutom Mode Portlet");
}
protected void doCustomConfigure(RenderRequest request, RenderResponse response) throws PortletException, IOException {
response.setContentType(request.getResponseContentType());
response.getWriter().println("Here is my custom configure mode!!!");
}
protected void doDispatch(
RenderRequest request, RenderResponse response)
throws PortletException, IOException{
 
/* don?t do anything if the window is minimized */
if (!WindowState.MINIMIZED.equals(request.getWindowState())) {
 
/* find out which portlet mode is being requested */
PortletMode requestedMode = request.getPortletMode();
PortletMode customPortletMode = new PortletMode("config");
 
/* if our custom mode is requested, call our custom do method */
if (requestedMode.equals(customPortletMode)) {
 
/* this is the call to our custom do <mode> method */
doCustomConfigure(request, response);
return;
}
/*if our custom portlet wasn?t called, allow the regular portlet
mode processing happen*/
super.doDispatch(request, response);
}
}
 
}
