Or maybe there is!..Almost a result, I am doing this now,
List<Modification> modItems = ServerEntryUtils.toServerModification(
ldifEntry.getModificationItemsArray( ) ,
directoryService.getRegistries(
).getAttributeTypeRegistry( ) );
modOp.modify( ldifEntry.getDn( ) , modItems ,clusterBypass );
Modification: replace
, attribute : entryCSN: '0x32 0x30 0x30 0x39 0x30 0x33 0x31 0x31
0x31 0x37 0x33 0x31 0x33 0x31 0x2E 0x30 ...'
It now blows up with the following exception,
javax.naming.NoPermissionException: Cannot modify the attribute 'entryCSN']
Why is it not possible to modify this? Is this a per-server unique
value? And if so I assume it won't hurt if I don't include it in the
Modification List in ldifEntry?
Thanks guys,
Yiannis.

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 :-)
