ClassCastException in rename()

[John D'Emic]

Hey All,

I'm encountering a ClassCastException in the rename() method of ServerContext. I'm not sure if I'm doing something wrong, but the code works with OpenLDAP but not with ApacheDS.  Here's the relevant lines from ServerContext:

 public void rename( Name oldName, Name newName ) throws NamingException
    {
        LdapDN oldDn = buildTarget( oldName );
        LdapDN newDn = buildTarget( newName );
       
        if ( oldDn.size() == 0 )
        {
            throw new LdapNoPermissionException( "can't rename the rootDSE" );
        }

        // calculate parents
        LdapDN oldBase = ( LdapDN ) oldName.clone();  <<<< ClassCastException

My client code is passing in org.springframework.ldap.support.DistinguishedName objects.  I could be mistaken, but it seems like the clone() should be on oldDn and not oldName.

Any help is appreciated,
-jd

Hi,

as you can see, the two DN are supposed to be LdapDN objects. If you pass some
org.springframework.ldap.support.DistinguishedName objects, you will
certainly get some ClasscastException, for sure...

Hmmm...shouldnt the method signature take LdapDN instances then instead of instances of Name?

yes, for sure.

But we are just in the middle of a big cleanup, to get rid of such
horrible things ...
