态类型在javax.persistence（A态类型必须指定）

我有这个运行时异常问题（使用一个关系数据库和Java容器基于对象 - 关系持久性解决方案。）态类型在javax.persistence（A态类型必须指定）

Exception [EclipseLink-7212] (Eclipse Persistence Services - 2.4.2.v20130514-5956486): org.eclipse.persistence.exceptions.ValidationException 
Exception Description: The attribute [submissionTime] from the entity class [class com.tdk.domain.Service] does not specify a temporal type. A temporal type must be specified for persistent fields or properties of type java.util.Date and java.util.Calendar.

但是，看在上帝的份上，这个类型已经是java.util.Date !!!!

@Temporal(TemporalType.TIMESTAMP) 
    @Column(name = "SUBMISSION_TIME") 
    public Date getSubmissionTime() { 
     return this.submissionTime; 
    }

这里完整堆栈跟踪

这是一个“编译问题”？这是AT RUNTIME的例外。 –

正在拾取列和时间标注吗？将日志记录转换为最好或全部，并检查EclipseLink在其部署阶段采集的内容。如果您在字段和属性上有注释，则只有一组将被拾取。还要检查你的带有注释的类的版本是否是在运行时拾取的类 - 它不会是多个版本的类首次引起奇怪的运行时问题。 – Chris

您是否正在导入java.sql.Date？ –
