This is part of the mapping I use to generate Java code and sql ddl:

<class name="Business" table="business">
<id name="bsnId" type="int" unsaved-value="null">
<generator class="native"/>
</id>
...
<component name="bsnAddress" class="Address">
<property name="address" column="address1" type="string" length="64"/>
</component>
...
</class>

<class name="Entity" table="entity">
<id name="entId" type="int" unsaved-value="null">
<generator class="native"/>
</id>
<many-to-one name="business" class="Business" column="bsnId"/>
...
<component name="entAddress" class="Address">
<!-- I would not like to repeat the properties below -->
<property name="address" column="address1" type="string" length="64"/>
</component>
</class>

I would not like to repeat the lines noted above in the second class. I also discarded the subclass or joined-subclass options because I don't want to join business and entity in the same table. I would also like to have hbm2java to generate the Address class, what makes it difficult to use a UserType. Is it possible?

Thanks.

PS: I use hibernate 2.1

No

Thanks anyway. I tought it might be a good idea.

You could try using XMLs feature of importing segments of XML.



This XML (include) file has the property lines in it for you component. eg:

Then in you mapping doco:


Note: This is using the XML parser's features not a Hibernate feature.

Thanks.

I was planning to use an ant task to pre-process the mpping file but your suggestion seems to be easier.
