Mysql and Tomcat 5.5 strange performance

Hello,

I am a user of the older MySQL 3.23 and Tomcat 4. We developed several applications using JSP and beans. These applications have been working great for over a year now.

We created a new development testbed using the latest Mysql and Tomcat 5.5 so we migrated them from the old mysql 3.23 and Tomcat 4 to this new testbed. Most of the JSPs work fine including the maintenance JSPs.

We also have a java program that continuously loads the Mysql DB with the latest status information (about 5 transactions per minute).

The issue is that a JSP which does a refresh shows the current status of an activity. On the older release the JSP page show the activity every 20 secs as programmed.
On the new release the first time the numbers are correct but then every 20 seconds it shows the same data.

Is there a caching parameter or some other configuration issue I am not aware of? Why would it not go out to the DB and get the latest data?

Thanks for your help!
