java - 如何解释我的堆栈跟踪？

Question

我使用 IBM RAD 8 并部署到 websphere，然后我得到这个堆栈跟踪:

ERROR ArendeProcessLoginServlet:142 - Fel i ArendeProcessLoginServlet, performTask(): 
javax.ejb.EJBTransactionRolledbackException: nested exception is: javax.ejb.EJBException: See nested exception; nested exception is: <openjpa-2.1.1-SNAPSHOT-r422266:1141200 fatal user error> org.apache.openjpa.persistence.ArgumentException: The type "class se.prv.pandora.arendeprocess.entity.Anstalld" has not been enhanced.

    at org.apache.openjpa.meta.ClassMetaData

这是什么意思？我应该采取什么步骤来解决该错误？

感谢您的帮助

看起来您的模型类“se.prv.pandora.ar​​endeprocess.entity.Anstalld”尚未得到增强。请参阅this有关如何在 openjpa 中增强模型类供您的应用程序使用之前的链接。
