Applet在Eclipse中運行良好;但在Chrome中運行給了InvocationTargetException

我做了一個Swing小程序，它將在Eclipse中運行，沒有任何問題，但是當我使用Chrome運行一個html文件時，我得到一個運行時異常：java.lang.reflect.InvocationTargetException。任何人都可以提出什麼是錯的嗎？這是我曾嘗試：Applet在Eclipse中運行良好;但在Chrome中運行給了InvocationTargetException

我讀過的InvocationTargetException環繞一些其他錯誤（不同的錯誤造成的呢），但我不知道哪個方法把try {}趕上（的InvocationTargetExceptionË ）{e.toString（）}得到一個有用的錯誤。
在線材料建議我用加多寶產生堆棧跟蹤，但又似乎不包含任何有用的信息，以找到異常的原因：

¿小程序有什麼作用？ – Alfabravo 2012-08-02 22:05:00

您的代碼是否使用任何反射（特別是[Method.invoke]（http://docs.oracle.com/javase/7/docs/api/java/lang/reflect/Method.html#invoke（java.lang .Object％2C％20java.lang.Object ...））或[Constructor.newInstance]（http://docs.oracle.com/javase/7/docs/api/java/lang/reflect/Constructor.html#的newInstance（java.lang.Object中...）））？ – 2012-08-02 22:05:57

我沒有明確使用Method.invoke或Constructor.newInstance。在這個錯誤出現之前，我從來沒有聽說過反思。 – user1572503 2012-08-02 22:31:07

問題是我在初始化init()方法之外的變量。看來Eclipse沒有這個問題，但用瀏覽器運行它 Java Plug-In會拋出一個java.lang.reflection.InterruptedThreadException。
