Dear all
i m using Hibernate 3.2.5.

i have got all mappings correct , i mean atleast it doesnt give me incorrect mapping error.
Except for one class it gives a warning :--

WARNING: composite-id class does not override equals(): payments
WARNING: composite-id class does not override hashCode(): payments
And then after some hibernate tasks
it gives me following line of Exception
.....

...
INFO: Default entity-mode: pojo
INFO: Named query checking : enabled
INFO: building session factory
INFO: Exception--->org.hibernate.MappingException: could not instantiate id generator

im a novice to hibernate
Please help me in correcting above Exception

Regards
Vikram

It does look like one.. but you have to post extract from your mappings in order to help you.

But if the object are saved in the database maybe it is just a warning and you can ignore it..
