jboss-ejb-client-Beispiel: Exception in thread "main" javax.die Benennung.NoInitialContextException:

Ich versuche, führen Sie das folgende Beispiel für eine durchaus irgendwann in eclipse.

https://github.com/jboss-developer/jboss-eap-quickstarts/tree/master/ejb-remote

Ich erstellt habe, die ein ejb-Projekt und importiert alle class-Dateien und setzen .properties-Dateien in META-INF. jetzt gibt es keine Fehler im code und ejbs bereitgestellt werden, die auf JBoss-server erfolgreich. Wenn ich versuche zu laufen RemoteEJBClient.java ich bin immer folgende exception, die ich bin nicht in der Lage, zu beheben.

Exception in thread "main" javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file:  java.naming.factory.initial

bitte helfen Sie mir im klären diese Frage
