I am building a java desktop application that I will sell in the usual way from a website. Users can download a full-featured trial version that will run for 30 days, and after that they can purchase a license over the web using a credit card. I'm wondering what design patterns might be involved when designing with updating in mind. I'd like to have the app check my web site for bug fixes and/or upgrades. I'm not sure what buzzwords to google for this, and I've never done it before, so any advice would be much appreciated. Thanks!
The soul is dyed the color of its thoughts. Think only on those things that are in line with your principles and can bear the light of day. The content of your character is your choice. Day by day, what you do is who you become. Your integrity is your destiny - it is the light that guides your way. - Heraclitus
