Define "access".
Is tomcat (which btw?) running and listening on port 8080?
Is mysql(-server) running and accepting connections from localhost on 3306?

Code:

sudo netstat -natp | grep -e 8080 -e 3306

Some tools/code to try.

Code:

lynx localhost:8080

mysql -uroot -p -h127.0.0.1

telnet 127.0.0.1 3306

Firewall rules work only if there's a listening service/daemon on the host to answer/satisfy the request.

fwNoRules + NoDaemon = No Access
fwRules + NoDaemon = No Access
fwRules + Daemon = Access
