Greetings...
In addition to the usual program guide, promotional materials, and what
must the absolute nicest bag I have ever seen given away as a conference
freebie, attendees of last week's JBoss World conference in Atlanta
received a Rubik's Cube, its white squares decorated with JBoss logos.
I'm sure this was fun for cubephiles (the guy next to me during the
keynotes scrambled and then solved his cube within two minutes) but I
wonder if the cube is the ideal metaphor for an open source application
server and partner projects. After all, there's only one way to play with
the cube, one way to get it right. That seems ironically restrictive,
doesn't it? Personally, I always preferred the freedom of the Rubik's
Snake: you could compete to build the ball shape faster than anyone else
(in my youth, I could do it in 8 seconds), or you could twist its
alternating 30-degree angles into whatever shape pleased you.
The JBoss World conference provided the stage for a number of
announcements from the company behind the popular open source application
server. "Welcome to a New World: JBoss World 2005" reports on the
announcements of a new standardized middleware platform combining JBoss
and other well-known open source projects, a new support portal, and a
JBoss-led open source repository. The article also covers keynotes from
partners HP and Intel, and a roundtable of JBoss customers.

EJB code is portable, but deploying from one application server to another
is not a matter of simply copying over files. In "Migrating a WebLogic
EJB Application to JBoss", Deepak Vohra shows how the incompatibility is
in the deployment descriptors and how "an application may be migrated to
JBoss by converting the vendor-specific deployment descriptors to JBoss."

In "A Look at Commons Chain, Part 2," Bill Siggelkow investigates how
Struts 1.3 uses Chain. "Struts uses Chain to replace its traditional
HTTP-request processing, which was handled by the RequestProcessor
class..." with the payoff that "...adding custom behavior to Struts
request processing is now easier and less obtrusive than ever before."
Bill is the author of "Jakarta Struts Cookbook."

In our feature article from java.net, Gianluca Brigandi looks into
"Integrating Java Open Single Sign-On in Pluto." In this article, he
provides an overview of the need for single sign-on in portlet containers
like Apache's Pluto. He walks through installing and configuring the
necessary pieces to support protection of portal content while still
providing a convenient end-user experience via a one-time authentication.
