1. Introduction 

Welcome to JBoss Community by Marc Fleury 

Welcome to the Source.  Here at JBoss we are about providing quality services behind a 

quality server.  In its 3 years of existence, you have come to know JBoss as the premier 

provider of Java middleware.   Just good java  is our moto.  We are not interested in selling 

you the app server, justifying outrageous licensing fees, or artificially differenciating our 

offering to stand out from the crowd.  We are about quality middleware. We now support all 

our products under the JBoss Group umbrella: a new breed of professional services company 

to come out of Open Source. 

We are now in our 3.x series, with a fourth generation container.  While we started with 

EJB, and we remain a quality EJB server, in fact one of the best on the market, we have 

expanded to implement the entire J2EE stack.  In one easy stack you will find an efficient 

HTTP server called WEB/JBoss (Web on JBoss) as well as a servlet engine and JSP engine 

(JSP/JBoss).  You will also find the latest EJB spec implemented just right in EJB/JBoss.  

JCA/JBoss in its latest incarnation (1.5 API) is fully supported as well as advanced security 

with JAAS/JBoss integration.    

But we do not stop here, beyond J2EE and the alphabet soup that comes with it you will find 

 just good java .  No non sense, no complications.  At the heart of it you will find JMX/JBoss, 

the Java Management eXtensions API.  Few vendors realize how powerful this specification 

is  they think it is  for management  but we know better than that.  JMX/JBoss is the base 

of our microkernel architecture.  JBoss is fully modular, but not  marketing talk modular , 

REALLY modular. Removing modules and adding modules DYNAMICALLY has never been 

simpler in JBoss. Just drag and drop from our deploy directory.  For those of you looking for 

the latest features of JBoss we ship the CMP2.0 EJB persistence engine, clustering and web 

services.   

So you are about to enter a world of goodies.  Don't let the FUD out there tell you JBoss is 

too simple or that JBoss is too complicated. JBoss is JUST RIGHT.  JBoss is full of 

architectural gems, from our minds to your minds, little tricks and patterns, no nonsense 

compilation free stubs and a JMX system level clean head approach to infrastructure.  From 

a deep blueprint about our interceptors and JMX combo, up to how the client interceptors
