classCastException when deploying alfrescon in JBoss 4

[shevek]

Hello:
  I am trying to deploy Alfresco in JBoss AS 4, but it's impossible. I get a classCastException in com.sun.facelets.components.RepeatRenderer. Perhaps there is a missing jsf jar?

Thanks in advance.

I used that instructions:
http://wiki.alfresco.com/wiki/Deploying_WAR_JBoss

worked for me.
( just plain copying war to deploy folder caused errors)
