Question

我正在创建我的第一个RestFul应用程序，我在Java / Netbeans开发方面缺乏经验。我有一个包含很少表的MySQL数据库;我基于数据库创建了一个新的Web应用程序项目和实体类。然后我基于实体类创建了一个RestFul Web服务。一切都很好，直到这一点。当我尝试测试RestFul服务时，我得到 error ：

type Exception report

messageInternal Server Error

descriptionThe server encountered an internal error that prevented it
from fulfilling this request.

exception

javax.servlet.ServletException: javax.ejb.EJBException root cause

这是我的 glassfish-resources.xml file

我检查过，我确实可以访问数据库并存在表格。

请帮助我，我不知道该怎么做。
