First of all, I wouldn't trust the network guys :) The firewall might be 
OK, but OK might mean, that it drops connections, when they are idle for 
too long.

That said, you have a few options to drive around such a limitation.

You could set "testWhileIdle" to true, so that you generate network 
traffic and thus keep open the firewall (again I assume it is the 
firewall, that corrupts your connections and I assume you are using a 
connection pool managed by tomcat). I believe you have to set 
"timeBetweenEvictionRunsMillis" to a postive value, or no idle testing 
will be done.

You might try the "maxConnLifetimeMillis" setting, so that old 
connections from the pool will not be used.

You might try to size the pool, so that it keeps no idle connections 
(but why should I use a pool then?).

Hope this helps

Are you using Tomcat's built-in authenticator?
