Re: [jetty-dev] Servlet 3.0 fragments and META-INF/resources

[Jan Bartel <janb@xxxxxxxxxxx>]

Hi Eirik,

The Servlet 3.0 (greater) emphasis on WEB-INF/lib is
certainly annoying to users used to greater flexibility :(

I agree we should think of a way to make it easier to use with
non-standard webapp deployments, such as an embedded scenario. While
that's happening, if you subclass WebInfConfiguration and override the
protected List<Resources> findJars(WebAppContext c) method to return
the set of jars you want to use, then all should be well. You can use
one of the WebAppContext.setConfigurations() or 
WebAppContext.setConfigurationClasses() methods to introduce your
WebInfConfiguration subclass.

cheers
Jan
