我是 EJB 的新手，我正在尝试对我部署在项目中基于新 OpenShift 3 (Origin) 中的 Wildfly 10.1 的 pod 上的无状态和有状态 bean 执行远程调用。我用于初始化客户端上下文的代码如下所示：
Properties clientProperties = new Properties();
clientProperties.put("remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED", "false");
clientProperties.put("remote.connections", "default");
clientProperties.put("remote.connection.default.host", "localhost");
clientProperties.put("remote.connection.default.port", "8080");
clientProperties.put("remote.connection.default.username", "****");
clientProperties.put("remote.connection.default.password", "****"); clientProperties.put("remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS", "false");
clientProperties.put("remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOPLAINTEXT", "false");
EJBClientContext.setSelector(new ConfigBasedEJBClientContextSelector(new
PropertiesBasedEJBClientConfiguration(clientProperties)));
Properties contextProperties = new Properties();
contextProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
contextProperties.put(Context.SECURITY_PRINCIPAL, "****"); //username
contextProperties.put(Context.SECURITY_CREDENTIALS, "****"); //password
Context context = new InitialContext(contextProperties);
String appName = "CloudEAR";
String moduleName = "CloudEjb";
String distinctName = "";
String beanName = "Calculator";
String qualifiedRemoteView = "cloudEJB.view.CalculatorRemote";
String lookupString = "ejb:" + appName + "/" + moduleName + "/" + distinctName + "/" + beanName + "!" + qualifiedRemoteView;
Calculator calculator = (CalculatorRemote) context.lookup(lookupString);
int sum = calculator.sum(10, 10);
我得到的错误信息是：

最初我尝试使用“jboss-ejb-client.properties”文件，但它甚至无法建立远程连接。现在我正在手动创建和配置 EJBClientContext，并且至少成功连接到远程服务器，但由于身份验证失败，调用失败。
我记得我们曾经通过在旧版本的 OpenShift 中删除“standalone.xml”文件中的“安全领域”参数来解决这个问题；但是我无法在新版本中找到该文件了。我一直在研究诸如秘密、卷等概念，但我真的不清楚它是如何工作的。当我创建一个新密钥并尝试将其与我的 pod 关联时，新的部署过程会失败。我真的很感激任何帮助。
