I've just developed a website using Java, for the HN November "Launch an App Month." It's a Javascript-heavy frontend plus Java backend app, with a whole separate background processing pipeline done in Java. I'll do a show and tell in couple days once it's ready. Java is great for rapid development once the development process is set up correctly. I've actually ported the app to Google App Engine in the middle of development once I learned of its generous hosting plan. Java is one of the two languages supported by GAE. I did use Python for quick scripts in import/export and building up data sets from dev environment to production servers.
