I found an error in ORACLE TOPLINK while adding table CUSTOMER, MOTHERBOARD and MEMORY from database to workbench. Any idea how to solve that error?
And other questions:
1. Does Toplink support inheritance and aggregation object table modelling? If it doesn't, what should I do?
2. Is there any example or tutorial using Toplink Foundation Library?
Thanks a lot.

Answer 1

What error do you get in the MW?
TopLink does support object-relational data-types, but the Mapping Workbench does not have support for object-relational data-types, so you may need to define your mappings through the TopLink Descriptor and Mapping Java code API. There is a section on object-relational data-type mappings in the TopLink User Guide.
