我想部署一個Vaadin/JEE6應用程序到TomEE。TomEE投擲IndexOutOfBoundsException
以下異常部署期間拋出：

我必須承認，我不知道爲什麼這可能會引發異常。在深入研究TomEE代碼之前，我想問問這裏有沒有人偶然發現了這個異常，並且可以給我一個提示，以尋找錯誤。
看起來像OpenEJB的錯誤或配置錯誤。在OpenEJB中至少有一個錯誤，就是爲什麼這個列表可能是空的，沒有引發更多非正式的例外。 – BalusC
看起來像沒有網絡模塊被認可 private void loadWebModule（AppModule appModule，StandardContext standardContext）WebModule webModule = appModule.getWebModules（）。get（0）; – stratwine
一個粗略的猜測 - 是Web應用程序一個沒有web.xml的Web應用程序？您可以通過設置以下系統屬性來檢查是否存在任何警告：openejb.validation.skip = false openejb.validation.output.level = VERBOSE – stratwine
