IllegalArgumentException with joined subclasses in 2.1 final

Kai · **Posted:** Mon Dec 15, 2003 11:24 am

Hi,
I have created a structure like: User extends Actor, Group Extends User.
Actors can have Permissions (See below the hbm.xml).
While adding a permission to a user or group I get the IllegalArgumentException during commit().
In BasicPropertyAccessor.java[96] I can see, that Hibernate tries to execute getId() on the target Permission but methods contains the clazz Actor?!
In 2.0.2 this code was running.

Code:

<hibernate-mapping>
  <class name="com.ssn.acx.api.persistence.collections.Actor" table="TestJActor" dynamic-update="true">
    <id name="id" column="id" type="long">
      <generator class="native">
        <param name="sequence">TestJActorSEQ</param>
      </generator>
    </id>
    <property name="name" type="string" not-null="true" unique="true"/>
    <set name="permissions" table="act_perm">
      <key column="permission_id"/>
      <many-to-many column="actor_id" class="com.ssn.acx.api.persistence.collections.Actor"/>
    </set>
    <joined-subclass name="com.ssn.acx.api.persistence.collections.User" table="TestUser" dynamic-update="true">
      <key column="actor_id"/>
      <property name="firstname" type="string" not-null="true"/>
      <set name="groups" lazy="true" table="user_groups">
           <key column="user_id"/>
           <many-to-many column="group_id" class="com.ssn.acx.api.persistence.collections.Group"/>
      </set>
    </joined-subclass>
    <joined-subclass name="com.ssn.acx.api.persistence.collections.Group" table="TestGroup" dynamic-update="true">
      <key column="actor_id"/>
      <property name="description" type="string"/>
      <set name="users" table="user_groups">
        <key column="group_id"/>
        <many-to-many column="user_id" class="com.ssn.acx.api.persistence.collections.User"/>
      </set>
    </joined-subclass>
  </class>
  <!--    Permission mappings  -->
  <class name="com.ssn.acx.api.persistence.collections.Permission" table="TestJPermission">
    <id name="id" column="id" type="long">
      <generator class="native">
        <param name="sequence">PermissionSEQ</param>
      </generator>
    </id>
    <property name="name" type="string" not-null="true" unique="true"/>
    <property name="description" type="string"/>
  </class>
</hibernate-mapping>

This is a FAQ

Sorry if I haver overlooked it, but I have found in the FAQ and forum two issues about IllegalAccessError one during configuration Hibernate and one with Tomcat.
I am working without Tomcat and the configuration is fine.
Do you mean one of these or another which I have not found.

I'm not sure that this is the thing mentioned in the FAQ. If you are truly certain that you have something that worked in 2.0.2 and it doesn't work in 2.1, then please submit a very simple main() method to JIRA so that I can reproduce the problem.

I have done some tests with this problem. It seems to be a problem with Hibernate and the log4j XML configuration.
I have added the Jira issue:

Code:

    <set name="permissions" table="act_perm">
      <key column="permission_id"/>
      <many-to-many column="actor_id" class="com.ssn.acx.api.persistence.collections.Actor"/>
    </set> 

Should be a collection of Permission. Please be more careful.

Sorry after your comment in Jira it is clear.
Im a little bit confused because of the dependency with logging.
Sorry and thanx!
