It is not at all good practice to have more than one mapping into your mapping files. So each mapping file should contain only one class mapping.
sudha,
you can create two mapping files(*.hbm.xml) and put class mapping with same class name and different table name.
If you find any difficulties, you can always come back. Please
show us some efforts.
