DynamicRoster implementation class should be configured in the init.properties file. As it’s an extension to the Presence and Roster plugins class should be configured either for both plugins:
sess-man/plugins-conf/jabber\:iq\:roster/dynamic-roster-classes=<class list> sess-man/plugins-conf/presence/dynamic-roster-classes=<classes list>
or globally:
sess-man/plugins-conf/dynamic-roster-classes=<classes list>
<classes list> is a comma separated list of classes.
