我不知道哪些文件，我需要在這裏展示，以幫助解決這個問題，請大家幫忙:(

currentEntityManager爲空

這是顯示錯誤日誌的代碼部分：

@Out(scope = ScopeType.SESSION)  
    EntityManager currentEntityManager;

錯誤很明顯，Seam正在嘗試刪除currentEntityManager值，但無法這樣做，因爲變量是null。因此，你需要明白爲什麼它是null（我認爲這是因爲emf是null或未打開）。

當currentEntityManager爲null（使用註釋的required選項）時，您可以指示Seam不抱怨。但是，如果您不希望它爲空，那麼您需要檢查原因。

@In(required=false) 
@Out(scope=ScopeType.SESSION, required=false) 
EntityManager currentEntityManager;

另外，爲什麼你在一個函數返回cem，爲什麼你不的cem值設置currentEntityManager目前尚不清楚。
