Two tables


Table Job
Table Employee


Employee(table)
CurrentJobId


Job( table )
JobId



Employee.hbm.xml
<many-to-one name="job" column="JobId" class="com.db.dataobject.Job"/>

Job.hbm.xml
<set name="employees" cascade="all" inverse="true" lazy="true">
<key column="CurrentJobId"/>
<one-to-many class="com.db.dataobject.Employee"/>

</set>



see the above example where the two columns are related i.e. the
currentJobId is the same as the JobId, and there are many employees to
one JobId. how do i represent that in the above two mapping files as
the names of the coulmns are different in each table?!?!

In the employee mapping for the job property, the column should refer to the CurrentJobId, not the JobId. Hibernate knows the class, so it will match the CurrentJobId to the JobId.

Employee.hbm.xml


The Job mapping looks ok AFAIK.
