Ouch I just realised this won't really ever work..ModifyOperationContext
requires a ServerModification item for it to work, which in turns
requires ServerAttribute to be constructed and I can't get any of them
out of an Ldif object in the context of a Modify operation...double damn!

Hello everyone :-)
I've got a problem trying to use LdifEntry with
ModifyOperationContext. If you remember from
previous emails, I'm using LdifEntry because it can be serialized.
I'm stuffing my Modification
objects in the LdifEntry object like so
for( AttributeType attributeType : list )
{
EntryAttribute entryAttribute = ( (ServerAttribute) entry
.get( attributeType ) ).toClientAttribute( );
ldiff.addAttribute( entryAttribute );
if( changeType.equals( ChangeType.Modify ) )
{
ClientModification mod = new ClientModification(
ModificationOperation.REPLACE_ATTRIBUTE ,
entryAttribute );
ldiff.addModificationItem( mod );
}
}
This serializes fine, however ModifyOperationContext.modify() gives
me a
java.lang.ClassCastException:
org.apache.directory.shared.ldap.entry.client.DefaultClientAttribute
cannot be cast to
org.apache.directory.server.core.entry.ServerAttribute
when I pass the LdifEntry object modification list to it because it
expects ServerAttributes and not ClientAttributes and as far as I
can remember, ServerAttributes are not serializable (?). Is there
any way I can get around this requirement?
Just store the initial entry.getAttribute() into the modification :
for( AttributeType attributeType : list )
{
EntryAttribute entryAttribute = ( (ServerAttribute) entry
.get( attributeType ) ).toClientAttribute( );
ldiff.addAttribute( entryAttribute );
if( changeType.equals( ChangeType.Modify ) )
{
ClientModification mod = new ClientModification(
ModificationOperation.REPLACE_ATTRIBUTE ,
entry.get( attributeType ) );
<----------------------
ldiff.addModificationItem( mod );
}
}
It should work.
Whoops :-)
