EJB yapılandırmasıyla Java JNDI

Question

JNDI yapılandırma sonu EJB 3.1 ve Oracle 12.1 DB ile ilgili bir sorunum var. kodum:

private static NewSessionBeanRemote lookupRemoteSessionBean() throws NamingException { 

    final Hashtable jndiProperties = new Hashtable(); 
    jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming"); 

    final Context context = new InitialContext(jndiProperties); 
    final String appName = ""; 
    final String moduleName = "EjbComponent"; 
    final String distinctName = ""; 
    final String beanName = NewSessionBean.class.getSimpleName(); 
    final String viewClassName = NewSessionBeanRemote.class.getName(); 
    System.out.println("ejb:" + appName + "" + moduleName + "" + distinctName + "/" + beanName + "!" + viewClassName); 
    return (NewSessionBeanRemote) context.lookup("ejb:" + appName + "" + moduleName + "" + distinctName + "/" + beanName + "!" + viewClassName); 
}

senin Context.URL_PKG_PREFIXES ayrıca aşağıdaki özellikleri ayarlayın gerekir: Eğer varsa, aynı zamanda

jndiProperties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory"); 
jndiProperties.put(Context.PROVIDER_URL, "http-remoting://127.0.0.1:8080"); 

Herhangi bir kimlik doğrulama türü için Context.SECURITY_PRINCIPAL ve Context.SECURITY_CREDENTIALS:

jndiProperties.put(Context.SECURITY_PRINCIPAL, "username"); 
jndiProperties.put(Context.SECURITY_CREDENTIALS, "password");
