Multiple POJOs to single table (existing db)

Hibernate version: 3.1

Sorry, new to hibernate!!

I have created some POJOs that are mapped to a single table.
the keys are the same. They seem to function ok in isolation, but I am
worried that this is something I should not be doing!!

e.g. What happens if I delete an object, I do not want this to remove the
whole row in the database; as this would impact the other POJOs.

Is there a Pattern for this interaction? maybe I should stop the delete/inserts from being called on these POJOs.

My Use cases are simply to allow view/updates on these objects
I have created the objects to match the individual use cases.

Perhaps I should create a large POJO mapping to the whole table
and embed components??

thanks

Can you post the mapping file and also explain why multiple pojos are required for a single table?

The 2 mappings just use different fields of the same table. This gives 2 seperate POJOs for different use cases.

e.g. View X Data and View Y Data where the keys are the same.
