In order to be a partition, class HelloWorldPartition implements the corresponding interface from org.apache.directory.server.core.partition.

suffixDn.normalize(core.getRegistries().getAttributeTypeRegistry().getNormalizerMapping());
Rdn rdn = suffixDn.getRdn();
// Create the only entry in this partition
ServerEntry entry = new DefaultServerEntry(core
.getRegistries(), this.suffixDn);
entry.put(SchemaConstants.OBJECT_CLASS_AT, SchemaConstants.TOP_OC,
SchemaConstants.ORGANIZATIONAL_UNIT_OC);
entry.put(SchemaConstants.OU_AT, rdn.getUpValue().toString());
entry.put("description", "hello, world", "a minimal partition");
this.helloEntry = entry;
