I was discussing again with Ales the server/xxx/lib-opt directory we've added a while back, and it seems to me a lot more appropriate to put any conditionally enabled .jars together with the corresponding deployer. I.e. deployers/seam.deployer/lib/jboss-seam-int-jbossas.jar With the proper classloading settings this lib, or other versions of it, should be conditionally put in the classpath by the seam deployer. This makes the deployer more self-contained and removes the extra directory bloat. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4186791#...
