Jakarta ee org.eclipse.persistence.exceptions.ValidationException:无法添加类型与现有查询冲突的查询

我有一个股票交易的JavaEE应用程序，它使用web服务调用EJB。在我在数据库中添加了一个额外的字段之前，一切都很正常。该应用程序提供以下例外情况：

我调试并发现异常是在ejb的getAllScrips方法中引发的 以下是托管bean方法和web服务方法：

private java.util.List<service.ScripMaster> getAllScrips() {
    service.StatelessWebService port = service.getStatelessWebServicePort();
    return port.getAllScrips();
}

public List<ScripMaster> getScripList() {
    scripList=new ArrayList<ScripMaster> ();
 scripList=getAllScrips();
    return scripList;
}

编辑： 在实体类ScripMaster.java中，我添加了以下代码：

 @Column(name = "PreviousClose", precision = 22)
    private Double previousClose; //new column
    @Column(name = "Change", precision = 22)
    private Double change; //new column

而他们的接力二传手正是如此

这是如何造成的，我如何解决它？

实际问题在问题开始出现之前就已经记录好了，可能与您正在执行的查询无关-只是碰巧这是应用程序中的第一次EM访问，容器正在将EM包装在代理后面

EclipseLink有一个在2.4中修复的bug，它会在部署阶段处于失败状态时导致此错误。失败后尝试使用工厂将导致它尝试重新添加JPQL查询，从而导致此错误。修补程序保留初始错误并将其重新引用，从而更容易找到初始原因。因此，您可以尝试使用EclipseLink 2.4夜间构建，但实际原因应该出现在EMF部署期间的日志中

---

您向应用程序添加了哪些代码来支持新字段？

我使用了不同的查询名称来解决这个问题。用“find”启动命名查询的名称似乎会引起问题。

目前，您使用哪种eclipse版本？这是EclipseLink 2.1.2的一个问题

---

我建议使用

javax.persistence\u 2.0.4.v201112161009

和

eclipselink.jar

版本和

eclipselink 2.4.1

你能发布你的ScriptMaster.findAll命名查询吗？@Gamb-我已经编辑了我的问题，将scripMaster.findAll查询包括在内

@NamedQuery(name = "ScripMaster.findAll", query = "SELECT s FROM ScripMaster s")

 @Column(name = "PreviousClose", precision = 22)
    private Double previousClose; //new column
    @Column(name = "Change", precision = 22)
    private Double change; //new column
