我曾经能够在 RAD 7.5.5 上使用 JNDI 运行调用 EJB 和 MQ 的独立 Java 应用程序。我升级到 RAD 8.5，当我尝试运行它时，我收到了错误Failed to create InitialContext using factory specified in hashtable。我还在为两个 RAD 版本使用相同的 WAS 7.0.0.9，所以我不确定为什么它现在不起作用。
在 RAD 8.5 中我需要做什么特别的事情吗？这是我的引导类路径条目：WAS v7.0 JRE, %WAS_RUNTIME%\com.ibm.ws.ejb.thinclient_7.0.0.jar, WAS v7.0 lib.
以下是我设置环境的行（RAD 8.5 似乎需要第二行）：
System.setProperty(Context.PROVIDER_URL, "iiop://localhost:2809");
System.setProperty("com.ibm.ws.naming.wsn.factory.initial", "com.ibm.websphere.naming.WsnInitialContextFactory");
下面是我的代码中的堆栈跟踪：
