    Remote connection failed: javax.security.sasl.SaslException: Authentication failed: the server presented no authentication mechanisms

    kayvan jamshidi Newbie

      I wrote a example remote ejb client  that connects to remote server wildfly 9.0.2 final ,

      here my code :

       

       

       

          public class EjbRemoteClient {

          public static void main(String[] args) {

       

              // Connection to Wildfly Server instance

              String host = "remote ip server";

              String port = "7273"; // Wildfly HTTP port

       

              Context remotingContext;

              try {

                  remotingContext = createRemoteEjbContext(host, port);

              } catch (NamingException e) {

                  System.err.println("Error setting up remoting context");

                  e.printStackTrace();

                  return;

              }

       

              String ejbUrl = "ejb:/myserver_core/someinterfaceImpl!com.art.dataserver.api.ejb.inf.BulkRemoteInf";

       

              someinterface mtnBulk;

              try {

                  mtnBulk = createEjbProxy(remotingContext, ejbUrl, someinterface .class);

              } catch (NamingException e) {

                  System.err.println("Error resolving bean");

                  e.printStackTrace();

                  return;

              } catch (ClassCastException e) {

                  System.err.println("Resolved EJB is of wrong type");

                  e.printStackTrace();

                  return;

              }

       

              // Call remote method with parameter

              try {

                 

                  AimedJobsModel aimedJobsModel =mtnBulk.getAimedJobs();

              } catch (Exception e) {

                  System.err.println("Error accessing remote bean");

                  e.printStackTrace();

                  return;

              }

          }

       

          /**

           * Create Remote EJB Context.

           *

           * @return remote EJB context

           * @throws NamingException

           *             if creating the context fails

           */

          private static Context createRemoteEjbContext(String host, String port) throws NamingException {

       

              Hashtable<Object, Object> props = new Hashtable<>();

       

              props.put(INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");

              props.put(URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");

       

              props.put("jboss.naming.client.ejb.context", false);

              props.put("org.jboss.ejb.client.scoped.context", true);

       

              //props.put("endpoint.name", "client-endpoint");

              props.put(Context.SECURITY_PRINCIPAL, "myusername");

              props.put(Context.SECURITY_CREDENTIALS, "mypass");

              props.put("remote.connection.default.connect.timeout", "15000");

              return new InitialContext(props);

          }

       

          /**

          @SuppressWarnings("unchecked")

          private static <T> T createEjbProxy(Context remotingContext, String ejbUrl, Class<T> ejbInterfaceClass)

                  throws NamingException, ClassCastException {

              Object resolvedproxy = remotingContext.lookup(ejbUrl);

              return (T) resolvedproxy;

          }}

       

       

      here is important sections of standalone-full.xml on server side :

       

          <subsystem xmlns="urn:jboss:domain:remoting:3.0">

                  <endpoint/>

                  <http-connector name="http-remoting-connector" connector-ref="default" security-realm="ApplicationRealm"/>

                  <outbound-connections>

                      <remote-outbound-connection name="remote-ejb-connection" outbound-socket-binding-ref="remote-ejb" username="myusername" security-realm="ejb-security-realm">

                          <properties>

                              <property name="SASL_POLICY_NOANONYMOUS" value="false"/>

                              <property name="SSL_ENABLED" value="false"/>

                          </properties>

                      </remote-outbound-connection>

                  </outbound-connections>

              </subsystem>

       

      and my exception is :
