Dynamic Portal

A new blog entry is put in Sun Portal Blog on Ajax usage in portlets.
Dynamic Portals

hmm.. The article and powerpoint slides were interesting but it did not add much to what we already know about ie. implementation of Ajax in JSR 168 through Servlets. The issue still remains of security, as this servlet can directly be called by not an authorized user , thus developer needs to do extra stuff to provide the authentication for servlet. The namespace is still a problem when using javascript library files. How one can identify if the library has already been added or not by some other portlet.

Concept of using JASON instead of xml/html for ajax communication is a promising idea. The new specifications JSR 286 and new features added to be able to support ajax calls will make the portal implementation with ajax a lot simpler. I feel more light should have been put on the event handling in new proposed specifications and IPC in new specifications. And how Sun is planning to implement them in the portal server.

GWT with Portlets

GWT is pushing the rich client concept in webapplication. I guess portals can use it to a great extend. Here are the recent article about it.

JSR 286 IPC

I was looking for an idea of what new features are added to jsr 286 for IPC. I found a few good articles on that topic. http://blogs.sun.com/nav/entry/understanding_portlet_2_0_jsr
