I have a many-to-many association defined as follows:

Code:

<set name="activationCode2package" table="activation_code2package">
            <key column="activation_code_id"/>
            <composite-element class="ActivationCode2Package">
               <property name="isCrashed" type="boolean" column="is_crashed"/>
              <property name="useDate" type="timestamp" column="use_date"/>
               <many-to-one name="pkg" class="Package" column="package_id"/>
            </composite-element>
        </set>

and

Code:

        <set name="activationCode2package" table="activation_code2package">
            <key column="package_id"/>
            <composite-element class="ActivationCode2Package">
               <property name="isCrashed" type="boolean" column="is_crashed"/>
              <property name="useDate" type="timestamp" column="use_date"/>
               <many-to-one name="activationCode" class="ActivationCode" column="activation_code_id"/>
            </composite-element>
        </set>

Obviously the primary key of the bridge table (package2activation_code) must be "pkg + activation_code"...
But... When I create DB with SchemaExport this table doesn't have primary key!

Shouldn't you have a many-to-many element in the mapping if you want to map such a relation? I don't see one in your mapping.
It might be better if you give the whole class and corresponding DDL generated.
