This week's book giveaways are in the Refactoring and Agile forums. We're giving away four copies each of Re-engineering Legacy Software and Docker in Action and have the authors on-line! See this thread and this one for details.
This "JavaRanch" forum is for discussing the site javaranch.com. We have many other forums on particular topics. Since the mechanics of streaming a data file depend a bit on the context, it's probably best for this to go in the Sevlets forum, since that's what you're writing. I will move this there for you.
