In short:

1. Can anyone confirm that they have succesfully migrated their EJBs to WildFly 8 and are still able to connect to them from a remote client?

2. Are you still connecting to port 4447 or is it now port 8080?

3. Did you change anything in standalone.xml to make the connection work?

I am asking, because I am having a hard time connecting from my remote client to my EJBs after I migrated to WildFly 8.0.0 Final.

I used to connect to my EJBs on port 4447, but when doing so I simply get a timeout with this exception:

java.lang.RuntimeException: Operation failed with status WAITING

  at org.jboss.ejb.client.remoting.IoFutureHelper.get(IoFutureHelper.java:94)

I did a comparison of the standalone.xml configuration files of JBoss 7.2 and WildFly 8. In the old file the standard sockets section contain this configuration

    <socket-binding-group name="standard-sockets" default-interface="any" port-offset="${jboss.socket.binding.port-offset:0}">

        <socket-binding name="remoting" port="4447"/>

This socket binding seems to be used by JBoss's remoting-connector configured here

        <subsystem xmlns="urn:jboss:domain:remoting:1.1">

            <connector name="remoting-connector" socket-binding="remoting" security-realm="ApplicationRealm"/>

        </subsystem>

Now, when looking for this WildFly 8's standalone.xml it seems this remoting configuration have been replaced by

        <subsystem xmlns="urn:jboss:domain:remoting:2.0">

            <endpoint worker="default"/>

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

This gave me a clue that the port 4447 has been replaced with port 8080. So now I have tried connecting using this simple test code

  properties.put("endpoint.name", "client-endpoint");

  properties.put("remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED", "false");

  properties.put("remote.connections", "default");

  properties.put("remote.connection.default.host", "127.0.0.1");

  properties.put("remote.connection.default.port", "8080");

  properties.put("remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS", "false");

  properties.put("remote.connection.default.username", "test");

  properties.put("remote.connection.default.password", "1234");

  final EJBClientConfiguration configuration =

  new PropertiesBasedEJBClientConfiguration(properties);

  final ContextSelector<EJBClientContext> selector =

  new ConfigBasedEJBClientContextSelector(configuration);

  EJBClientContext.setSelector(selector);

However, with this code I get the following exception

Caused by: java.lang.IllegalStateException: EJBCLIENT000024: No EJB receiver available for handling [appName:wefend-server, moduleName:wefend-ejb, distinctName:] combination
