In a string of recent articles, I have discussed downloading, installing and running demos for a number of different tools, frameworks and libraries that support push-style (web) applications in one way or another. I have looked into ‘classic’ comet with Grizzly, Atmosphere and CometD as well as ADF Active Data Service and WebLogic Pub/Sub (Bayeux) Channels. I have also looked to WebSockets with jWebSocket, again Atmosphere and CometD and also with Kaazing. I am now working on a series of articles in which I use each of these frameworks and push infrastructures to implement the same simple push-style application – to see how that goes and to compare the various implementations. The functionality I will be implementing is simple:

  • through the web client (HTML 5/javaScript), a user can select an image from a list of ’slides’
  • the selection of the image is communicated to the server (background WebSocket based or alternatively regular AJAX)Comet (Bayeux)/Long Poll style)
  • the server informs all connected clients about the selected image through a pushed message (background WebSocket based or alternatively Comet (Bayeux)/Long Poll style); these clients all synchronize that slide More >

APEX plugins contributed to the APEX community by AMIS developers

I have to admit that, even though I have tried on several occasions to dive head first into APEX, so far I have only wet my feet. I have played a little with APEX 4.0, liked the development experience [a lot better at least than the 3.x world] and found that many concepts are the same, whether your do APEX, ADF or [presumably] .NET web application development.

One of the nice features in APEX 4.0, that allows for more more organized, better structured development with lots more reuse potential, is the plugin framework. Through this framework, interesting and reusable pieces of functionality can be shared within and across applications – as well as across the APEX developer’s community. And that community is something to be reckoned with with many, many developers around the world.

Some very enthusiastic and quite active members of the APEX community work at AMIS. And they have produced a number of plugins, and shared several on the Plugin Directory: http://www.apex-plugin.com/index.php.

ADF 11g : Using jQuery and ADF to provide a fading user feedback

Last week someone asked me if it was possible to inform the users of his application about the fact that data has been changed. No problem I told him. Whenever you use an actionListener or action that is implemented by a method in a bean, you can use showPopup() to show a popup from a backing bean. This was however not what he wanted. The usecase is a little more sophisticated: Save data, and inform the user without showing a popup that has to be ‘clicked’ away. In this post I describe how to achieve this with jQuery (more…)
