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

[Benson Margulies <bimargulies@xxxxxxxxx>]

Cefn,

if you look at the bottom of that bugzilla, you will see that it notes
that there is a (mistaken?) use of the Maven 'provided' scope which
results in the dependencies being effectively not declared -- or at
least there was when I went through this before.
