Repository <foreignkey ..> option : Generate index on foreign key. 
-------------------------------------------------------------------

                 Key: OJB-126
                 URL: http://issues.apache.org/jira/browse/OJB-126
             Project: OJB
          Issue Type: New Feature
          Components: RDBMS platform-specific support, XDoclet module
    Affects Versions: 1.0.4
         Environment: Oracle databases, and database supporting foreign key 
constraints 
            Reporter: Bruno Cros
            Priority: Minor


Regarding to Oracle recommendations, when using foreign key constraints, large 
tables referencing any tables to be updated or deleted, works better when table 
have a database index based on the foreign key codes. 

This is necessary to avoid dead lock errors (ORA-00060).

The suggested option "generate_index=yes" could be put in <foreignkey > 
declaration and means that project schema script process generates index 
creation script  (regarding to <foreign key>  fields) in project schema sql 
script.
