Hibernate version:3.0.5

I have mapped views with classes. During starting up of application on Websphere Applicaiton Server we are getting following warning from Hibernate HbmBinder

[11/24/08 9:35:54:510 MET] 00000020 HbmBinder I org.hibernate.cfg.HbmBinder bindRootPersistentClassCommonValues Mapping class: com.sample.dm.impl.SampleAddressDE -> VSAMPLE_ADDR
[11/24/08 9:35:54:555 MET] 00000020 HbmBinder W org.hibernate.cfg.HbmBinder bindCompositeId Could not perform validation checks for component as the class com.sample.dm.impl.SampleAddressDE was not found


Although, it is a Warning only and my application is working fine. I just want to know if there are issues in loading class mapped to a view that is causing class not found Warning above.

I could also not found detailed working mechanism of HbmBinder with respect to a Databse View.

Thanks.
