    Failed to connect to any server.

      I can't get remote access from my client to the server application.

      My EjbRemoteClient.java:

      package com.illucit.ejbremote;
      
      import static javax.naming.Context.INITIAL_CONTEXT_FACTORY;
      import static javax.naming.Context.PROVIDER_URL;
      import static javax.naming.Context.URL_PKG_PREFIXES;
      
      import java.util.Hashtable;
      import java.util.Map;
      
      import javax.naming.Context;
      import javax.naming.InitialContext;
      import javax.naming.NamingException;
      
      import com.illucit.ejbremote.server.ExampleService;
      import java.util.Properties;
      
      /**
       * Remote EJB Client.
       *
       */
      public class EjbRemoteClient {
      
      
          /**
           * Run example.
           * 
           * @param args
           *            (not used)
           */
          public static void main(String[] args) {
      
              Context remotingContext;
              try {
                  //Set jndi properties
                  Properties jndiProperties = new Properties();
                  jndiProperties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
                  jndiProperties.put(Context.PROVIDER_URL,"http-remoting://10.7.97.48:8080");
                  // username
                  jndiProperties.put(Context.SECURITY_PRINCIPAL, "ejbappuser");
                  // password
                  jndiProperties.put(Context.SECURITY_CREDENTIALS, "e3q5o-tbp");
                  // This is an important property to set if you want to do EJB invocations via the remote-naming project
                  jndiProperties.put("jboss.naming.client.ejb.context", true);
                  // create a context passing these properties
                  remotingContext = new InitialContext(jndiProperties);
              } catch (NamingException e) {
                  System.err.println("Error setting up remoting context");
                  System.out.println(e.getMessage());
                  return;
              }
      
      
              // Syntax: ejb:${appName}/${moduleName}/${beanName}!${remoteView}
              // appName = name of EAR deployment (or empty for single EJB/WAR
              // deployments)
              // moduleName = name of EJB/WAR deployment
              // beanName = name of the EJB (Simple name of EJB class)
              // remoteView = fully qualified remote interface class
              String ejbUrl = "/ExampleService/ExampleService-ejb/ExampleServiceImpl!com.illucit.ejbremote.server.ExampleService";
      
      
              ExampleService service;
              try {
                  service = (ExampleService)remotingContext.lookup(ejbUrl);
              } catch (NamingException e) {
                  System.err.println("Error resolving bean");
                  System.out.println(e.getMessage());
                  return;
              } catch (ClassCastException e) {
                  System.err.println("Resolved EJB is of wrong type");
                  System.out.println(e.getMessage());
                  return;
              }
      
              // Call remote method with parameter
      
              String toGreet = "World";
      
              String exampleResult;
              try {
                  exampleResult = service.greet(toGreet);
              } catch (Exception e) {
                  System.err.println("Error accessing remote bean");
                  System.out.println(e.getMessage());
                  return;
              }
      
              // Hello World!
              System.out.println("Example result: " + exampleResult);
      
              // Retrieve result from EJB call
      
              Map<Object, Object> systemProperties;
              try {
                  systemProperties = service.getSystemProperties();
              } catch (Exception e) {
                  System.err.println("Error accessing remote bean");
                  return;
              }
      
              System.out.println("Wildfly Home Dir: " + systemProperties.get("jboss.home.dir"));
      
          }
      
      
      }
      

       

      I get the following error message:

      Failed to connect to any server. Servers tried: [http-remoting://10.7.97.48:8080 (java.net.ConnectException: Connection refused: no further information)]

      But I can connect to the wildfly server. If I type 10.7.97.48:8080 in my webbrowser, it appears the welcome page.

      How can I find out, what It's wrong?
