Eclipse Galileo + Glassfish v3：JPADeployer部署時出現NullPointerException

Question

我創建了一個非常簡單的「企業應用程序」項目，其中包含約7個實體bean和一個無狀態會話bean。我還配置了一個Glassfish v3實例作爲我的應用服務器運行。不幸的是，當我嘗試發佈的EAR到GlassFish，我得到如下回應：

Answer 1

這NPE看起來莫名其妙地接近問題＃11387（它不是完全一樣的問題，但它可能是同一原因...或部署子組件中的另一個錯誤）。因此，我的建議是：

1. 嘗試使用最近的每晚構建（上述問題已在3天前在樹幹中修復，我沒有仔細檢查確認它完全不相關）。
2. 填充new issue堆棧跟蹤和理想情況下，如果問題仍然存在。
