last packet sent server 1 ms ago.

add following lines /etc/tomcat6/policy.d/webapps.policy file: 

permission java.net.socketpermission "127.0.0.1:3306", "connect,resolve";  permission java.util.propertypermission "file.encoding", "read";

also comment out in /etc/mysql/my.cnf 

#bind-address = 127.0.0.1

this guess.
