RecoverableDataAccessException in Spring Batch Admin

Hi,

I successfully deployed spring batch admin to tomcat 7.0, however, I repeatedly get the below exception when accessing the url for the first time after longer pauses (e.g. over night). After restarting tomcat, it works fine again.

Can anybody advice how to get rid of this strange behaviour?

Thanks and br,
Elmar

How is your connection pool configured? I believe that error is due to the app attempting to use stale connections.
