using term vectors

[Harsch, Timothy J. (ARC-TI)[PEROT SYSTEMS]]

Hi,
I am trying termVectorComponents in SOLR.  Per wiki I am trying to define 
component and handler.  I define it so:
<schema name="example" version="1.1">
        <searchComponent name="tvComponent" 
class="org.apache.solr.handler.component.TermVectorComponent"/>
        <requestHandler name="tvrh" 
class="org.apache.solr.handler.component.SearchHandler">
                <lst name="defaults">
                        <bool name="tv">true</bool>
                </lst>
                <arr name="last-components">
                        <str>tvComponent</str>
                </arr>
        </requestHandler>
...
</schema>

But when I query I get "unknown handler: tvrh"

Am I putting the XML definitions in the correct place?
