It will depend a great deal on the nature of your application and how many end users you think you may have. Also, how will you manage your storage/database (internal to the 5 boxes, external array, two extra boxes on fail-over etc)? Is your application read heavy or write heavy? Also, will your users be connecting securely using SSL/TLS & what type of load balancer will you use out the front (and will it have SSL accelerators)? If Tomcat and your firewalls (obviously you have firewalls!) are configured correctly, I don't really see a great deal of enhanced security offered in option 2.
