Question

I have a following domain model:

Entity1 -> ValueType1-> Entity2

How can I write the mapping file to represent the above situation (while retrieving Entity1)?

PS: I know I can use component tag when value type does not refer to another entity (in this case Entity2).

Thanks

You can use many-to-one inside your component to reference Entity2:

<class name='Entity1' table='entities_table'>     <id name='Id' column='id' unsaved-value='0'>       <generator class='native' />     </id>      <component name='NameOfValueType1Property' class='ValueType1'>         <many-to-one name='NameOfEntity2Property' class='Entity2' />     </component> </class> 

In this case Entity2 needs to be a persistent class with its own mapping file.
