Hi Kiran,
Now you can override the foreign key column name in the JPAEdmMappingModel
configuration. The changes are part of commit =
http://git-wip-us.apache.org/repos/asf/olingo-odata2/commit/fc8c4ff9
To override the foreign key column name following would be the steps.
Steps
1) In the mapping model under JPAEntityType --> JPAAttributes Element add a
JPAAttribute Element.
2) The JPA Attribute Element name takes the Join Column Name
Example
<JPAEntityType name="SalesOrderItem">
<EDMEntityType>SalesOrderLineItem</EDMEntityType>
<EDMEntitySet>SalesOrderLineItems</EDMEntitySet>
<JPAAttributes>
<JPAAttribute
name="liId">ID</JPAAttribute>
<JPAAttribute
name="soId">SalesOrderID</JPAAttribute>
<JPAAttribute
name="Material_Id">mID</JPAAttribute>
</JPAAttributes>
<JPARelationships>
<JPARelationship
name="salesOrderHeader">SalesOrderHeaderDetails</JPARelationship>
<JPARelationship
name="materials">MaterialDetails</JPARelationship>
</JPARelationships>
</JPAEntityType>
In the above example the Join Column name Material_Id is mapped to mID.
I hope this solves the problem
Thanks
Kind Regards
Chandan

> Project: Olingo
> Issue Type: New Feature
> Components: odata2-jpa
> Affects Versions: V2 2.0.0
> Reporter: Kiran G
> Priority: Minor
>
> If I set ODataJPAContext.setDefaultNaming(false) then the attributes for join
> column is of form FK_<JoinColumn Name>, there by exposing the foreign column
> name in $metadata url. It would be be nice just to have the JPA attribute
> name itself with a suffix 'fk' instead and not expose the Database column
> name.
> If this is not possible atleast provide support to override this name in
> JPAEdmMappingModel configuration XML.
