 Post subject: duplicate import problem with homonymous subclass

I have a class : com.seanergie.authentication.Role, and a subclass com.platre.authentication.Role

So, in my hibernate-mapping document, H vabe a <class name="com.seanergie.authentication.Role"> that holds a <subclass name="com.platre.authentication.Role">.
The full mapping document is bellow.

This generates a MappingException: duplicate import: Role
The full stack trace is bellow.

But if the subclass has a slightly different name, like com.platre.authentication.RoleZ, then everything works fine.

It seems that hibernate doesn't uses the full qualified class name, and that leads to this duplicate import.

Is it forbidden to have a subclass having the same name as the parent class, even if the fully qualified names are different ?
More generally, what precaution should we use regarding class names ?

Hibernate version: 2.1.6

Mapping documents:
Code:
<?xml version="1.0" encoding="UTF-8"?>
<hibernate-mapping>
    <class
        name="com.seanergie.authentication.Role"
        table="roles"
        dynamic-update="false"
        dynamic-insert="false"
        select-before-update="false"
    >

        <id
            name="unid"
            column="unid"
            type="java.lang.String"
        >
            <generator class="uuid.hex">
            </generator>
        </id>

        <discriminator
            column="roleClass"
            type="string"
        />

        <version
            name="version"
            type="int"
            column="version"
            access="property"
            unsaved-value="undefined"
        />

        <property
            name="name"
            type="java.lang.String"
            update="true"
            insert="true"
            access="property"
            column="name"
        />

         <set
            name="accesses"
            lazy="true"
            inverse="true"
            cascade="all-delete-orphan"
            sort="unsorted"
        >
              <key
                  column="role"
              >
              </key>
              <one-to-many
                  class="com.seanergie.authentication.RoleAccess"
              />
        </set>

        <subclass
            name="com.platre.authentication.Role"
            dynamic-update="false"
            dynamic-insert="false"
            discriminator-value="role"
        >
        </subclass>
    </class>
</hibernate-mapping>

Hi Sylvain,

I am having exactly the same issue. I tried to change the discriminator-value in one of the mapping, but this doesn't help. Have you made any progress on that issue on your side ?

Greetings,
R

Sorry, no, I didn't make any progress except on deciding to stop using classes with the same name.

Until now, it's ok, but I hope we will have a fix or a clarification before the projects becomes too big.
