Subject Re: tomcat caching issue
Date Fri, 30 Sep 2005 12:31:32 GMT
Based on everything written so far - there is no evidence tomcat would be 
chaching anything.

I'd suggest placing as much debug code in your code as possible via a logging 
pacakge such as log4j/commons-logging so the log information can be turned on 
via configuration directives.
