我曾經能夠運行獨立的Java應用程序，該應用程序使用RAD 7.5.5上的JNDI調用EJB和MQ。我升級到RAD 8.5，當我試圖運行它時，我收到了錯誤Failed to create InitialContext using factory specified in hashtable。我也使用相同的WAS 7.0.0.9爲兩個RAD版本，所以我不知道爲什麼它現在不工作。RAD 8.5無法運行調用EJB和MQ的獨立Java應用程序
RAD 8.5中有什麼特別的東西需要處理？ 這是我的引導類路徑條目：WAS v7.0 JRE,%WAS_RUNTIME%\com.ibm.ws.ejb.thinclient_7.0.0.jar,WAS v7.0 lib。
下面是其中I設置環境的線（第二行似乎有需要爲RAD 8.5）：
System.setProperty(Context.PROVIDER_URL, "iiop://localhost:2809");
System.setProperty("com.ibm.ws.naming.wsn.factory.initial", "com.ibm.websphere.naming.WsnInitialContextFactory");
下面是從我的代碼堆棧跟蹤：
