[ojb-users] How define composite keys using OJB.

[Weaver, S. <Sw...@ri...>]

I'm accessing legacy data that has some of it's tables using composite
(multiple) primary keys.  How is this accomplished in OJB?

Thanks,
Scott

That's quite easy:
For each attribute in your persistent class representing a Primary key 
column in your DB add a <primaryKey>true</primaryKey> elements to their 
respective FieldDescriptors in the Repository.

That's all!

Details for Reference- and CollectionDescriptors are mentioned in 
tutorial 3.

HTH,

Thomas
