篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了使用JBoss AS 7连接到DB2 db的JPA-Hibernate：HHH000183：没有为查询类找到持久化类相关的知识，希望对你有一定的参考价值。
JBoss模块版本1.5.1.Final-redhat-1
接近在对象中返回数据...但到目前为止，没有骰子。我可以连接。我可以执行查询。我可以获得实体经理。但是我收到了这个错误：
[org.hibernate.hql.internal.QuerySplitter] (default task-1) HHH000183: no persistent classes found for query class: SELECT c FROM com.bank.ro.Collateral c where c.Id = 992469
我有以下项目结构;我在使用IntelliJ：

- java
- com
- bank
- ro
Collateral.java
- dao
JPAUtility.java
JPQLDataAccessor.java

PricingSvcResource.java

我认为这一切都是密不可分的，尽管我们都知道......事情可以在没有宣布自己的情况下密切相关。
如果有人有任何想法，请告诉我。更多的喋喋不休导致错误：

答案
更新：修复是.jar up persister类并将其放在EAR_file / lib文件夹中。然后重新部署.ear。
这是不好的。这意味着我必须使.jarring the persister class（es）并将它们复制到EAR_file lib之前.earring up .war等等常规的东西，尤其是。如果我的坚持类改变了，尽管它们可能不会太多。
可能这对于更动态的业务类也是必要的，但也许不是因为我认为这是一个Hibernate范围的问题（好吧，我希望如此）。在我的情况下，我将不得不更新构建脚本，以便每次运行构建时为我执行此操作。
有一个原因是为什么发明了春天。 :)
