I've partially given it to you already. I'm assuming for the purposes
of this thread you have tomcat 5.5.x or tomcat 6.0.x and are using the
tomcat provided database pooling. Find the <Resource ... /> element in
your webapp's context xml file where you defined your database pool and
add an attribute named validationQuery with a value of "select 1". Then
restart your webapp.
