Develop/Deploy Portlets using PortalPack2.0Beta

I just created a new voice over screencast on how to develop portlets using PortalPack 2.0 Beta with NetBeans 6.0 Beta 1 and GlassFish V2.
The screencast demonstrates how to develop a simple portlet using PortalPack and deploy it on OpenPortal Portlet Container 2.0 Beta. Check it out

Running Web Applications/Portlets as desktop applications

Mozilla Labs has an interesting technology - Prism - that aims to quickly bridge the gap between web applications and the computer desktop. Instead of trying to come up with a completely new presentation technology like Flex, Silverlight, JavaFX etc. they have a simple program called Prism that will allow any web application to run outside the browser as a desktop application, so that each web application runs in its own window. It isn't rocket science and there have been similar technologies in the past. But Prism is much more usable and easy to use. I use Prism to run my Gmail and Yahoo Mail as desktop windows. That way my Firefox is free for other stuff and next time I have to restart my browser (which I very frequently do because Firefox can leak memory like a sieve) I don't have to bring up Gmail and Yahoo Mail again. Also the performance of Firefox is not affected because of the email clients that are constantly open.

 There has always been a requirement to run JSR 168 portlets on the desktop as native desktop applications. Prism can be a great solution to do this in a simple and easy manner. Just double clicking on an icon on the desktop will bring up a JSR 168 Portlet running inside Prism. And with Google Gears we can perhaps even make the portlet work offline. :)

JSR 286 Eventing Portlet Example and XML Portlet Available in Portlet Repository

touripc portlet

Check out these portlets that were recently added to the Portlet Repository!

The Tour IPC Portlets showcase an example of using JSR 268 Eventing for interportlet communication.  There is a tour list portlet that contains a listing of tour locations and the date of the next tour.  When the user selects a tour from the list the tour detail, tour map, and tour weather portlets are updated with information about that tour.

The XML Portlet is a simple portlet that performs an XSL translation on an XML file. The XML and XSL files are specified in the portlet preferences

You'll find the binary, source code, and documentation for all of these portlets and several others at the Portlet Repository Downloads page.  If you didn't find the portlet you were looking for or you'd like to contribute a portlet, then drop us a line and let us know.

OpenPortal WSRP Project JAX-WS migration effort

OpenPortal WSRP Project has released the first set of install instructions for the JAX-WS branch, the install instructions are available on the project wiki.

This is the first drop from the jaxws_branch, the branch was created a while back to facilitate the migration of the WSRP implementation from the older webservice stack (JAX-RPC) to new webservice stack (JAX-WS).  For feedback, please report issues to users@wsrp.dev.java.net or using issue tracker

The trunk of the Open Portal WSRP Project is still on JAX-RPC.

JSR286 explained : Public Render Parameters

Recently the JSR 286 draft was released for public review. The list of major changes in this new spec can be found in a previous blog.

In JSR 168, the render parameters set in processAction is only available in the render of the same portlet.

With the new feature "Public Render Parameter", the render parameters set in the processAction of one portlet will be available in render of other portlets also. Using public render parameters instead of events avoids the additional process event call.

See some commentary on the Public Render Parameter feature.

Technical Note: Managing Ajax Container

Student: Master, what is Ajax?

Zen Master: Ajax was a Greek hero, but if you tell that to any Java programmer you might become the subject of ridicule. But do not get offended. Ajax today means Asynchronous JavaScript and XML and it is a hero among Web development applications.

Student:  Then, Master, what is Ajax Table Container?

ZM: Answers to your questions are everywhere, but I recommend you read this Technical Note on Managing the AjaxTableContainerProvider.
