I would be glad to hear what is your development cycle and how you deploy new features to production cluster... How do you deploy them to the production cluster? With bash scripts and rsync, ant, maven or any other automation tool? I would be thankfull if you could point me to any resource describing best practices in developing, deploying and automatization of java project in unix/linux environment..
