[Anthill-pro] exception in log

[Varban]

Hi Byron,

this is an exception coming from Tomcat when it attempts to recover the 
session for the AnthillPro app. This does not affect in any way AnthillPro. 
If you want to get rid of it, however, you need to use a context file in order 
to deploy the AnthillPro.war file (instead of just copying the file to the 
webapps directory) and add the following to the AnthillPro context:
<Manager className="org.apache.catalina.session.PersistentManager" 
saveOnRestart="false"/>


Here is an example of the contents of a context file:

<Context path="/AnthillPro" docBase="/opt/AnthillPro/dist/AnthillPro.war"
         debug="0" privileged="true">
	<Manager className="org.apache.catalina.session.PersistentManager" 
saveOnRestart="false"/>
</Context>

If you are switching to a context file do not forget to remove the 
AnthillPro.war file from the webapps directory or you will have two instances 
of AnthillPro running at the same time.

Regards,
Varban
