Erik,

Thanks, I will fix the typos in the metadata. I've copied this to jdo-experts-ext so they can respond to your question in point 1 regarding columns in a superclass table that map to fields of a subclass..

Hi,

I have some metadata notes for the company model (package-derby.orm):

1. the column salary must allow null, and if we look in the java class, it's a
double value. Should the metadata explicit says the column is null or it's
implied by the fact it's a subclass using superclass-table strategy?

       <class name="FullTimeEmployee">
           <inheritance strategy="superclass-table"/>
           <field name="salary" column="SALARY"/>
       </class>


<class name="FullTimeEmployee"> <inheritance strategy="superclass-table"/> <field name="salary"> <column name="SALARY" allows-null="true"/> </field> </class>

2. The mapped-by attribute for fields employees and fundedEmps is not using the
correct case. The below is correct

       <class name="Department" table="departments">
           <datastore-identity strategy="identity" column="ID"/>
           <field name="name" column="NAME"/>
           <field name="company" column="COMPANYID"/>
           <field name="employees" mapped-by="department"/>
           <field name="fundedEmps" mapped-by="fundingDept"/>
       </class>

3. The field "insid" must be removed from the Insurance class when under the
orm/datastoreidentity folder.

       <class name="Insurance" table="insuranceplans">
           <inheritance strategy="new-table">
               <discriminator strategy="class-name" column="DISCRIMINATOR"/>
           </inheritance>
           <field name="insid" column="INSID" primary-key="true"/>

Regards,

Erik Bengtson
