All, 

The JSF situation in JBoss has gone from bad to worse.  In the pre-4.2.0 
servers, if you wanted to package your own JSF implementation with a web app, 
you had to delete the JSF libraries folder that ship with JBoss.  From all the 
trouble I read on various forums, users had only some success doing this.  
Telling me to modify my app server to deploy a single app is "bad".

But, at least with 4.2.0 CR-2 (and I assume 5.0.0 Betas), there is no way to 
package your own JSF libraries with your web app!  Check this wiki link for 
proof:

The important line to look for is this little dandy:

jars to your WAR!!

Before you continue, note:  Um, NO!!  

Maybe I WANT my own JSF implementation jars deployed!  Maybe I've got something 
working on an older version of JSF and don't want anything to change.  The 
whole point of J2EE is to give us deployment options not available in J2SE.  
You guys are getting just a little too JBossy, if you forgive the pun, by 
telling ME how I need to package MY app!

But, the implications of this are worse, MUCH worse.  

1) You're squatting on a public namespace - you don't own javax.faces, you own 
org.jboss.  If you want to ship your own mutant faces server-wide, fine, do it, 
just repackage everything so it pollutes your namespace and not mine.  

2) You're acting very proprietary.  You're not J2EE anymore, now you're 
J2EE+JBoss Faces+JBoss 
Log4J+JBoss-whatever-specific-versions-you-bundle-and-force-us-to-use.  Stop 
doing me favors, you're in the wrong.  I hereby revoke any JBoss J2EE 
Certification until further notice.

3) You're attempting to engage in vendor lock-in, plain and simple.  I should 
be able to take my WAR that deploys fine on WebLogic, WebSphere, and Geronimo 
and deploy it on JBoss with only JBoss vendor deployment descriptor changes.  
But you take away my power in more than just the JSF case to decide what 
libraries and versions I can use.  And, your vendor specific deployment 
descriptor tweaks for classloader control are toothless!!  You are telling me 
to make a special version of my app, just for JBoss.  No, it is not going to 
happen, I reject your vendor lock-in attempt!

Thoughts?  Am I way off base?  Oh, and by the way, citing JBoss technicalities 
or idiosyncrasies is no excuse.  The other vendors don't share your design 
issues to such an extent.  Tell me how to invert or suppress the appserver 
classloader so that I can override your JSF libraries, or I will not support 
deployments to JBoss.
