I have a jersey project in this structure, which consist of swagger
annotations . I have used it with standalone tomcat server and the API is
running fine. Now I am trying to run the same API with an embedded Grizzly
server. I have written the main function for that as follows:
import org.glassfish.grizzly.http.server.HttpServer;
import org.glassfish.jersey.grizzly2.httpserver.GrizzlyHttpServerFactory;
import org.glassfish.jersey.server.ResourceConfig;
import java.io.IOException;
import java.net.URI;
/**
* Main class.
*
*/
public class Main {
// Base URI the Grizzly HTTP server will listen on
public static final String BASE_URI = "http://localhost:8087";;
/**
* Starts Grizzly HTTP server exposing JAX-RS resources defined in this
application.
* @return Grizzly HTTP server.
*/
public static HttpServer startServer() {
// create a resource config that scans for JAX-RS resources and
providers
// in de.fraunhofer.fit.mas package
final ResourceConfig rc = new
ResourceConfig().packages("de.fraunhofer.fit.mas","io.swagger.jaxrs.listing");
// create and start a new instance of grizzly http server
// exposing the Jersey application at BASE_URI
return GrizzlyHttpServerFactory.createHttpServer(URI.create(BASE_URI),
rc);
}
/**
* Main method.
* @param args
* @throws IOException
*/
public static void main(String[] args) throws IOException {
final HttpServer server = startServer();
System.out.println(String.format("Jersey app started with WADL
available at "
+ "%sapplication.wadl\nHit enter to stop it...", BASE_URI));
System.in.read();
server.stop();
}
}
Unfortunately, my servlet configure file is not being found. I get a error
of this kind :

Can someone help me in this regard?
