Re: [Resteasy-users] Problem with resteasy test application

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Your application will extend javax.ws.rs.core.Application (defines your 
root resources and providers). The classes you return in your 
implementation of the
      public abstract Set<Class<?>> getClasses();
method defines the classes used for per request method dispatching.

Your singletons are specified by what you return in the getSingletons() 
method.

I believe the spec says that the default model is Singleton.

Perhaps some other list member knows the root cause of the error "Class 
is not a root resource" even though the class is annotated with the 
@Path annotation.
