Should Jetty be downloaded as part of JBoss to have
it "embedded" for best performance, or can Jetty be a
separate download for use both in JBoss, and in other
installations? Can a separate Jetty still be embedded
into JBoss with the "plain download" of JBoss?
You need the jetty-plugin.sar to embed jetty.
This is part of jboss. Its main purpose is mapping
jboss deployment to jetty deployment, but it does other
things like logging integration.
