This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread 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.
