Hello,

If ur table has composite primary keys, you need to implement the hashCode()
method of ur primary key class to return a well-distributed integer
depending on
the values of the member variable which constitute the primary key.
Orielly's
EJB gives some idea on how to design the method. It says u can use the
String
class' hashCode() method. u can create a String which contains the
concatenated
values of the member variables and  u can return the result of the
hashCode()
method of the resulting String.
I hope this information could be useful. Thanks.
