this is my first post on the page and I am working on Netbeans 8 with mysql and hibernate and I used the hibernate tool for the mapping. And I get this error: Caused by: org.hibernate.MappingException: Foreign key (FK_4s7nihascmjcx73pa1244h9fi:adm_roles_usuarios [tipoId])) must have same number of columns as the referenced primary key (adm_usuariosgeneral [tipoId,idUsuario])
The tables have the following structure on the DB: Table admUsuariosgeneral: tipoId, idUsuario(both PK and also FK to other table, they are the primary keys of that other table) and has other columns that arent important here.
Table adm_roles_usuarios: tipoId, idUsuario, idRol (all of them PK. tipoId and idUsuario are FK to admUsuariosgeneral and idRol FK to other table; idRol is the PK of that other table)
So as you can see the error is because of the FK in adm_roles_usuarios but that FK has both key atributes of the admUsuariosgeneral table.
Here I post the mapping of admUsuariosgeneral (Netbeans didnt generate a mapping for adm_roles_usuarios) in which if Im not wrong I can see the FKs defined correctly:
