Re: Embedded collections of non-PC objects

[Craig Russell]

Hi Andy, JDO2 defines an attribute "serialized" that specifies whether the contents of a field should be serialized and dumped into a single column, and therefore not queryable. It does allow for any serializable data to be stored, regardless of whether the data is persistence-capable or not. So I think it is a requirement for the Reference Implementation... To help clarify this for the TCK, we can/should add the "serialized" attribute to the columns in the metadata that are embedded.

JPOX persists collections of non-PC's in a join table. Is there a join table  here ? because you have none in your metadata. Are you expecting us to create some massive BLOB column and dump all of the  collection into that ? because we don't support that currently, and I don't  have any requests from users to do such a thing (since querying of the  elements would be getting close to impossible). --  Andy Java Persistent Objects - JPOX Craig Russell Architect, Sun Java Enterprise System http://java.sun.com/products/jdo 408 276-5638 mailto:[EMAIL PROTECTED] P.S.
