對於Facebook iframe應用程序，我們加載文件瀏覽器Java applet。在PC上的所有主流瀏覽器以及Mac上的Firefox上都可以正常工作。它也可以在Mac上的Safari中的iframe之外加載。iframe中的Java Applet無法在Mac Safari中加載
但是，只要在Safari/Mac中的iframe中調用頁面，小程序就不會加載。我們確實彈出了已簽名的applet許可權，但在此之後，加載只會旋轉，直到超時。
我已經在Facebook以外的iframe中測試過了，所以我知道這不是Facebook問題。還確保在Safari中啓用了Java並使其處於最新狀態，並且在控制檯中未觀察到相關的錯誤消息。
是否有其他人遇到此問題，如果有，是否有可以實施的解決方案或解決方法？
更新：從下面的Java控制檯輸出。始終掛在liveconnect調用的相同位置，不會拋出錯誤。
