運行簡單EJB應用程序的問題

Question

我目前正在運行一個使用無狀態會話Bean的簡單EJB應用程序。我正在使用Personal Glassfish 3.0開發NetBeans 6.8，並在我的系統上安裝了Java EE和Java SE。我不知道它是否是相關的，但我正在運行Windows7 64位版本。我實現的Session Bean只有一個方法sayHello（）;它只是在屏幕上打印出你好。當我嘗試運行應用程序，我發現了以下錯誤：

服務器還顯示此錯誤消息：

你認爲是什麼問題？這仍然是我的第一個EJB應用程序，所以我是這個API的新手。

Answer 1

刪除所有EJB並重新啓動Glassfish服務器。看看你是否有任何錯誤。如果您在沒有EJB的情況下出錯，那麼您的Glassfish安裝有問題。

如果Glassfish在沒有EJB的情況下正常啓動，那麼請發佈您的EJB代碼。 EJB代碼可能存在一些問題。

Answer 2

用戶Pascal Thivent非常友善地刪除了包含此問題的答案的帖子，因爲一些奇怪的和奇怪的原因。所以我將不得不重新發布解決方案。

所以基本上解決方案是：

1：Glassfish的被扔了很多的警告，因爲它被安裝在一個目錄，它的路徑名有空間的「程序文件」。所以要解決這個問題，只需將它安裝在C：/

2：關於拋出的NullPointerException（請參閱第一篇文章並向下滾動一下），似乎有一個問題，請參閱此鏈接https://glassfish.dev.java.net/issues/show_bug.cgi?id=11494 with glassfish和java6u18 。所以要解決這個問題，要麼等待java在未來的更新中修復這個bug，要麼降級到java6u17或更低版​​本。

希望這可能會有所幫助。
