Re: [jetty-users] Serving JSPs from Jetty - What am I missing

[Benson Margulies <bimargulies@xxxxxxxxx>]

If you just remove 'provided' from the POM you publish, all would be
well for us embedders. Presumably, the provided is in there for the
case where it's part of the larger distro that just has these things
lying about. However, for the embedded, case, the default scope would
be what the doctor ordered. Perhaps a separate published
'jsp-for-embedding' item that has the other scope?
