Hello EveryOne,
                       i've mapped many2many between user and skill tables ,when it is uni-directional works fine but the problem occurs when i made it to bi-directional. i've written many2many mapping in user class 

The following exception  is thrown when i try to insert  record.

Caused by: java.sql.BatchUpdateException: ORA-01400: cannot insert NULL into ("SYSTEM"."CUSER_SKILL"."CUSER_USERID")

CUSER_USERID(column) is getting created automatically in join table.


thanks in advance.
