I'm using this treecache.xml with success:

Code for testing:
| <table border="1">
| <tr>
| <td><b>Short term cache ('/5sec'):</b></td>
| <td>
| <s:cache region="/5sec" key="now" enabled="true">
| <h:outputText value="#{form.info.now()}" />
| </s:cache>
| </td>
| </tr>
| <tr>
| <td><b>Long term cache ('/forever'):</b></td>
| <td>
| <s:cache region="/forever" key="now" enabled="true">
| <h:outputText value="#{form.info.now()}" />
| </s:cache>
| </td>
| </tr>
| </table>
