Hi,

I would like to know if it is possible to share the definition of a <component> between different mapping files.

I am currently doing the following:

Component Comp is used by class A and B. Currently I duplicate the definition of Comp in both mapping files:

<hibernate-mapping>
<class name="A" table="a">
...
<component class="Comp" name="comp">
<property name="p1" type="string" />
...
</component>
...
</class>
</hibernate-mapping>

<hibernate-mapping>
<class name="B" table="b">
...
<component class="Comp" name="comp">
<property name="prop1" type="string" />
...
</component>
...
</class>
</hibernate-mapping>

Maintenance of the component is problematic as any changes requires an update to the mappings for A and B. Is there a way to reference a component from one mapping file to another? I've looked in the documentation and these forums but didn't find and answer.

Thanks.
David

I'd say use xml entity references to include some file containing the component mapping. And thing about if this is probably a good sign that it should not be a component but a real entity.

Thanks. I'll use xml entities.
I'm not sure why I didn't think about it... Anyway, thanks for the help.

By xml entity references are you implying using the
<!ENTITY xxxxx SYSTEM "filename"/> option. I tried this but the parser complained since the mapping file already has a reference to a dtd specification.
Can you provide an example.
