Dear all

I created this <subclass> mapping and hibernate 3.1 refuses to load it with a non-specific message:

"Could not read mappings from resource: com/softwareag/seicr/dao/Modification.hbm.xml"

I am desperate by now and at the end of my resources or maybe I got blind to see errors.

Could anyone please take a look at this mapping and maybe spot some errors?

Your help would be graciously appreciated.

Kindest regards and many thanks

Markus

Mapping:
<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>

<class name="com.softwareag.seicr.dao.Modification" table="BAF_MODIFICATION">

<property name="position" column="POSITION"/>

<subclass name="ModTextDAO" discriminator-value="MODIF_TEXT">

</subclass>

</class>

</hibernate-mapping>
