我使用WebSphere 8.5托管我的应用程序，并在应用程序服务器上配置了一些JDBC资源。我还使用瘦客户机运行时库开发了一个客户机应用程序。以以下方式执行JNDI查找时：

env.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory");
env.put(Context.PROVIDER_URL, "corbaloc:iiop:serv:2809");
Context initialContext = new InitialContext(env);
DataSource ds = (DataSource) initialContext.lookup("cell/node/servers/server/MYDB");

引发以下异常：
