Terry,
you can also prevent Tomcat from trying to persist these sessions across
restarts.
Go to your tomcat conf directory, there should be a file called context.xml
which has the following snippet in it :
<!-- Uncomment this to disable session persistence across Tomcat
restarts -->
<!--
<Manager pathname="" />
-->
If you uncomment the Manager element the error messages should go away.
regards,
Harry
