Hello,
I have mad some types and typed tables in a schema on oracle 10g.
My database respects the Object Relational model, in which I work with VARRAY, TYPES, NESTED TABLES, PL/SQL,...

I have already install Enterprise Pack for Eclipse, and also have the Weblogic server, And I can generate tables. But the problem is that it gives to me this tables with wrong types, until they contains in fact other tables as Objet column, and also the types are not supported.

Please need a help !

Thank's in advance Smile

Object relational data-types are not very commonly used. Most users use the relational model.

You can map object relational data-types in EclipseLink using the @Struct, @Structure, @Array annotations.
DDL generation is not supported for object-relational data-types, you will need to use your own DDL scripts.
