Persistent (remember me) login using geronimo

I have found this:

I'm using tomcat with geronimo, so it says to add something like this to my geronimo-web.xml

<manager>TomcatManager</manager>
<gbean name="TomcatManager" class="org.apache.geronimo.tomcat.ManagerGBean">
<attribute name="className">org.apache.catalina.session.PersistentManager</attribute>
<attribute name="initParams">maxActiveSessions=10
                             maxIdleBackup=10
                             maxIdleSwap=11
                             minIdleSwap=5
                             store.className=org.apache.catalina.session.FileStore
                             store.checkInterval=10
                             store.directory=d:/testFolder/session
</attribute>
</gbean>

However, My geronimo-web.xml for the webapp was generated by Eclipse and has prefixes. I haven't figured out how to properly add the update. I'd love to see a complete xml file with prefixes that will properly configure PersistentManager.

Here's what my current geronimo-web.xml looks like:
