delegate HTTP request to Jersey - jersey-2.0

Question

I have a nano HTTP based web server, that is supposed to delegate its calls to a jersey 2.22.2. On the webserver class constructor I declare an ApplicationHandler as a instance variable:
ApplicationHandler newHandler;
Then in the constructor I initilize it and register a Sample resource class:
Object[] instances = new Object[1];
instances[0] = new SampleResource();
ResourceConfig app = new ResourceConfig();
app.registerInstances(instances);
newHandler = new ApplicationHandler(app);
On the method that processes Http requests I create a ContainerRequest and execute the apply method on the application handler :
SecurityContext secContext = new SecurityContext() {
#Override
public Principal getUserPrincipal() {
return new Principal() {
#Override
public String getName() {
return "user";
}
};
}
#Override
public boolean isUserInRole(String s) {
return true;
}
#Override
public boolean isSecure() {
return true;
}
#Override
public String getAuthenticationScheme() {
return null;
}
};
PropertiesDelegate propertiesDelegate = new PropertiesDelegate() {
Map<String, Object> props = new HashMap<>();
#Override
public Object getProperty(String s) {
return props.get(s);
}
#Override
public Collection<String> getPropertyNames() {
return props.keySet();
}
#Override
public void setProperty(String s, Object o) {
props.put(s, o);
}
#Override
public void removeProperty(String s) {
props.remove(s);
}
};
ContainerRequest request = new ContainerRequest(new URI("http://localhost:2000"), new URI("/test"), session.getMethod().toString(), secContext, propertiesDelegate);
Future<ContainerResponse> responseFuture = newHandler.apply(request);
ContainerResponse response = responseFuture.get();
Object entity = response.getEntity();
Below is the code for the SampleResource class :
public class SampleResource {
#GET
#Path("test")
public Response testMethod() {
return Response.status(Response.Status.OK).build();
}
}
The main reason for doing this is that I want to call a custom API that injects objects into the annotated resource classes.
Stepping through the code, all I get is a NotFoundException.

If you want to inject custom Objects to the resources class you can do that in two waus
using #Context -- By adding your custom object to application context
usign #Inject -- By binding the application to resource config
to use #Context , you need to extend the java.security.Principal object and declare your object fields, and you can instantiate and assign values by using security context.
to user #InJect , you need to register org.glassfish.hk2.utilities.binding.AbstractBinder like below
public class MyApplication extends ResourceConfig {
public MyApplication() {
packages("org.foo.rest;org.bar.rest");
register(new AbstractBinder() {
#Override
protected void configure() {
bindFactory(ObjectThatneedtoInject.class).to(yourClass.class);
}
});
}
}
