javax.называющий.NoInitialContextException: не удается создать экземпляр класса: orj.jboss.называющий.дистанционный.клиент.InitialContextFactory

Я столкнулся с простой проблемой и обратиться за помощью.

Вот сообщение об исключении:

  1. ОК, возможно, у вас есть ошибка в конфигурации :

     p.put(Context.INITIAL_CONTEXT_FACTORY, "orj.jboss.naming.remote.client.InitialContextFactory");
    

    Потому что Орж .jboss.называющий.дистанционный.клиент.InitialContextFactory я думаю, что хорошее название-org .jboss.называющий.дистанционный.клиент.InitialContextFactory
