Re: Setting a Filter for a JAX-RS resource class or application

Hello all

I'll try to explain what I want to acomplish: Basically I would like tointegrate Bruno Harbulot's SPNEGO authentication filter into a simpleJAX-RS server.

I cannot use application.setGuard(...) since authentication isimplemented as a Filter instead of a Guard.


Here is the main class:

public class ExampleServer {

   public static void main(String[] args) throws Exception {
       // create Component (as ever for Restlet)
       Component comp = new Component();
       Server server = comp.getServers().add(Protocol.HTTP, 8182);

       // create JAX-RS runtime environment

JaxRsApplication application = newJaxRsApplication(comp.getContext());


       // Authentication filter derived from Bruno Harbulot's code
       // How can I activate this filter?
       SpnegoFilter filter = new SpnegoFilter();

       // attach ApplicationConfig
       application.add(new ExampleAppConfig());

       // Attach the application to the component and start it
       comp.getDefaultHost().attach(application);
       comp.start();

       System.in.read();
       comp.stop();
   }
}

The ApplicationConfig class:

public class ExampleAppConfig extends ApplicationConfig {

   public Set<Class<?>> getResourceClasses() {
       Set<Class<?>> rrcs = new HashSet<Class<?>>();
       rrcs.add(EasyRootResource.class);
       return rrcs;
   }
}

The RAX-RS Resource class:

@Path("easy")
public class EasyRootResource {
   @Context
   SecurityContext sc;

   @GET
   @Produces("text/html")
   public String getHtml() {
       return "<html><head></head><body>\n"
               + "This is an easy resource (as html text).\n"
               + "</body></html>";
   }
}

The SPNEGO filter:http://git.kato.mvc.mcc.ac.uk/bruno/spnegofilter.git/?a=blob_plain;f=src/main/java/uk/ac/manchester/rcs/bruno/spnegofilter/SpnegoFilter.java;hb=HEAD

Roman
