Java 持久化单元部署失败问题,java,Java,当我部署我的CRUDWEB web应用程序时，它会抛出如下所示： SEVERE: Exception while deploying the app [CRUBWEB] : Exception [EclipseLink-28019] (Eclipse Persistence Services - 2.5.0.v20130507-3faac2b): org.eclipse.persistence.exceptions.EntityManagerSetupException Exception

当我部署我的CRUDWEB web应用程序时，它会抛出如下所示：

SEVERE:   Exception while deploying the app [CRUBWEB] : Exception [EclipseLink-28019] (Eclipse Persistence Services - 2.5.0.v20130507-3faac2b): org.eclipse.persistence.exceptions.EntityManagerSetupException
Exception Description: Deployment of PersistenceUnit [CRUBWEBPU] failed. Close all factories for this PersistenceUnit.
Internal Exception: Exception [EclipseLink-0] (Eclipse Persistence Services - 2.5.0.v20130507-3faac2b): org.eclipse.persistence.exceptions.JPQLException
Exception Description: Problem compiling [SELECT e FROM custt e]. 
[14, 19] The abstract schema type 'custt' is unknown.

请帮助，谢谢。

我猜问题在于您没有创建所需的数据库架构。我在MySQL的authenticate DB下创建了数据库表CUST。CUST表的架构是什么？CUST（cid（PK，自动生成，cname varchar，accno（FK），bal）
