我有一個jsf項目已經部署在oracle應用程序服務器多次之前，它使用eclipse鏈接2.2.0，在最近的一個新安裝站點崩潰時加載數據DB，因爲它一直執行相同的查詢千次然後它拋出stackoverflow異常eclipselink重複相同的查詢千次然後stackoverflow例外
如果我從我的本地jdev連接到相同的新安裝應用程序啓動正常，所以它似乎服務器配置問題，而不是編碼問題。用於 代碼創建對象描述符用於讀取實體
List<EntityPCEntity> entityList = new ArrayList<EntityPCEntity>();
entityList = (List<EntityPCEntity>)this.getTABSEntityManagerFinder().getEclipseLinkAdapter().readMultipleDAOs(TLEntityPCDAO.class);
return entityList;
