Going insane with requestHandler definition.

[banished phantom]

Hello everyone ! I'm new in the Solr list. I'va been using Solr 1.2 for a
while and also the replication through rsync. As the new Solr was released I
tried the new replication method,
so I read : http://wiki.apache.org/solr/SolrReplication. There it says :

"Replication feature is implemented as a RequestHandler .So, the
configuration is similar to any normal RequestHandler"

and an example is shown :

<requestHandler name="/replication" class="solr.ReplicationHandler" >
    <lst name="master">
        <!--Replicate on 'optimize' it can also be  'commit' , 'startup'. It
is possible to have mutiple entries  -->
        <str name="replicateAfter">commit</str>
        <!--If configuration files need to be replicated give the names here
. comma separated -->
        <str name="confFiles">schema.xml,stopwords.txt,elevate.xml</str>
    </lst>
</requestHandler>

So, I put the same example in my solrconfig.xml. However when Solr is fired
up, I get :

Could someone please tell me what I'm doing (or NOT doing) wrong ?.

Thanks a lot,
