Hibernate Compsite Key without new class

Question

I have simple hibernate mapping ```

``` I do not want to create separate class for Composite Key. So, acctype and accnum are part of OtherAccount class only. Class implements serializable interface and hashCode() and equals() methods. I am able to create new object and persist it using, session.save(). But how can I retrieve existing object ? In session.get() method how to specify composite key ? ``` In session.get(OtherAccount.class, HOW TO SPECIFY COMPOSITE KEY HERE ) ```

Accepted Answer

Create an instance of `OtherAccount` and set just those two fields. Hibernate doesn't care that the instance has more fields than it needs.
