wildfly swarm: lookup ejb remote interface

I have generated two simple wildfly swarm projects. First has EJB facade with Remote interface, second should lookup it and send message. So second should be as client.

I am used Wildfly swarm version 2017.9.4

My EJB facade lookup paths:

        java:global/ejb-one/PingFacade!io.project.core.interfaces.PingFacadeRemote
        java:app/ejb-one/PingFacade!io.project.core.interfaces.PingFacadeRemote
        java:module/PingFacade!io.project.core.interfaces.PingFacadeRemote
        java:jboss/exported/ejb-one/PingFacade!io.project.core.interfaces.PingFacadeRemote
        java:global/ejb-one/PingFacade
        java:app/ejb-one/PingFacade
        java:module/PingFacade

My client :

 public static void main(String[] args) {
        BackendConnectionManager manager = new BackendConnectionManager();
        try {
            manager.getPingFacadeRemote().savePingMessage("halloooooo");
        } catch (NamingException ex) {
            Logger.getLogger(BackendConnectionManager.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
    public  PingFacadeRemote getPingFacadeRemote() throws NamingException {
        final Hashtable jndiProperties = new Hashtable();
        jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
        jndiProperties.put(Context.INITIAL_CONTEXT_FACTORY,  "org.wildfly.naming.client.WildFlyInitialContextFactory");
              jndiProperties.put(Context.PROVIDER_URL,"http-remoting://localhost:8080");
                 //jndiProperties.put(Context.PROVIDER_URL,"http://localhost:8080");
        final Context context = new InitialContext(jndiProperties);

        return (PingFacadeRemote) context
                .lookup("java:global/ejb-one/PingFacade!io.project.core.interfaces.PingFacadeRemote");
    }

Added client dependencies to pom.xml

I do not what is whole dependencies for client and always has

javax.naming.CommunicationException: WFNAM00018: Failed to connect to remote host [Root exception is org.jboss.remoting3.ServiceOpenException: Unknown service name]
    at org.wildfly.naming.client.remote.RemoteContext.getRemoteTransport(RemoteContext.java:80)

    at io.project.ejbtwo.rest.BackendConnectionManager.main(BackendConnectionManager.java:43)
Caused by: org.jboss.remoting3.ServiceOpenException: Unknown service name

Also how to solve problem with passing security credentials in client lookup?

In BackendConnectionManager.java , line 57, you are trying to look up the service java:global/ejb-one/PingFacade!io.project.core.interfaces.PingFacadeRemote , but it seems to not exist. PingFacadeRemote interface is a part of ejb-core module. Yes, it is true that you implement it in ejb-one module, but you registered the interface as a remote ( @Remote(PingFacadeRemote.class) , in PingFacade.java ).

You might try to replace it with java:global/ejb-core/PingFacade!io.project.core.interfaces.PingFacadeRemote .
