我在嵌入模式下使用openEjb來測試無狀態會話bean，它具有一個注入EntityManager。但是，當我運行測試時，它會失敗，因爲它無法初始化應用程序。當我看到控制檯時，我也可以看到與無法找到persistence.xml有關的錯誤。openejb嵌入容器找不到persistence.xml
注意：我嘗試將WebContent以及META-INF放入類路徑中，但這也沒有幫助。
更新：
也有一些是關於使用OpenEJB的日食+資源時查找非常奇怪。
- 我將WebContent添加到源文件夾。我停止收到persistence.xml錯誤，但現在我得到一個錯誤，這表明openejb找不到任何託管資源
- 我將WebContent添加到源文件夾，但使用不同的輸出文件夾（對輸出文件夾使用允許輸出文件夾） ，並persistence.xml錯誤開始再次發生
- 我將META-INF複製到'測試'，這是所有測試的源文件夾，並且一切運行正常
- 關於點1和2，問題似乎事實上，WEB-INF也被包含在WebContent中。如果我排除WEB-INF，那麼openejb可以在測試中找到persistence.xml，並且測試運行正常
我對於發生的事情一無所知。
我粘貼下面的所有相關錯誤和代碼。從失敗的JUnit測試在Eclipse
