Problem using @DiscriminatorValue - making the value given case insensitive
Hi,
I have a class OrderStatusReport with InheritanceType 'JOINED' and i have used the column "service_class" as the discriminator column .Here is the code snippet.
@Table(name = "order_status_report")
@Inheritance(strategy=InheritanceType.JOINED)
@DiscriminatorColumn(name="service_class",discriminatorType=DiscriminatorType.STRING)
public class OrderStatusReport implements Serializable {}
Now i have declared one of my sub class as below using the @DiscriminatorValue annotation with value as "Audit"
@Entity
@Table(name="order_status_report")
@DiscriminatorValue(value="Audit")
public class AuditOrderStatusReport extends OrderStatusReport {
/** Creates a new instance of AuditOrderStatusReport */
public AuditOrderStatusReport() {
}
}
Now since one of the records of table 'order_status_report' has the value 'AUDIT'(full capital letters) instead of 'Audit' for the column 'service_class'' i am getting an exception 'Missing class for indicator field value'.Here is a complete stack trace of the exception thrown:

Can somebody help me with this?Is there any way of giving more than one value for discrimator value annotation?Is there any way of telling to use 'Audit' as @DiscriminatorValue irrespective of the case in which it is given?
