任何想法？爲什麼eclipselink需要jboss中的某些東西？我需要什麼jboss jar。我會使用打開的jpa，但由於某種原因退出後，從我的應用程序持續一些它開始給一堆stackoverflow錯誤。

能否請您發表您的persistence.xml文件？更好的是，如果您可以發佈代碼片段以獲取EntityManager。 – Behrang 2010-04-13 15:10:22

如果你的項目是不應該使用的JBoss可言的，但仍需要一定的JBoss類，這可能是指：

無論是默認的服務器是JBoss的（服務器視圖）
或您persistence.xml在yourProjectEJB/ejbModule/META-INF並參考JBoss的
