<Component> and hierarchy of classes

Hibernate version: 2.0.3

I have the abstract class Price that has two subclasses RealPrice and Yield. I want to use Price as a <component> in other class . Is it possible to do this without giving an <uid> to the class Price?

Thanks in advance

No, only entities can be polymorphic. Use a normal entity mapping and cascade="all".

example:

<property name="price" column="price" type="serializable"/>

I'm using Mysql and I'm storing it in a field of type "varchar" (255)
