I am a university student working on a research project that involves migrating a web application to Amazon's cloud. I spent the last semester working with servlets and was able to get the majority of the app's functionality working using a java servlet running in Tomcat. I am now trying to integrate Amazon Web Services such as the SimpleDB and E-mail service. I develop using the Eclipse Java EE for Web Developers Indigo IDE. I have the AWS plugin installed and am able to run sample code that Amazon provides to call SDB and SES successfully. However when I attempt to call a service like

I have been using AWS (Amazon Web services) and in particular simpleDB for a couple of smartphone apps using their iOS/android client libraries. So far, the data was very benign so I didn't worry too much about data protection. My next app project will require a "users" table/domain containing usernames and passwords. What I'm worried about is that someone reverse-engineer the Android java version of the app, then it will be easy to get all the simpleDB data, including all the passwords. the basic TVM thing (Token Vending Machine, where a temporary token replaces the AWS credentials which are

I am working on a game on the iPhone that will use SimpleDB for game data storage and I'd like to be able to timeout some database entries. I figure i'll have some cron job that looks at the timestamp of each entry and if it's delta is greater than X i'll time out that entry(change a var in it so it is once again available for selection by users). My issue is i don't know how to unify the timestamps. What do i do if a user has their system clock screwed up and it's off by a couple hours or even days? What i'd like is to get the system time from the SimpleDB servers when i insert, but i believe

Loading any of Amazon's listed public data sets (http://aws.amazon.com/datasets) would take a lot of resources and bandwidth. What's the best way to import them into AWS so you start working with them quickly? bardiir You will need to create a new EBS Instance using the Snapshot-ID for the public dataset. That way you won't need to pay for transfer. But be careful, some data sets are only available in one region, most likely denoted by a note similar to this. You should register your EC2 instance in the same region then. These datasets are hosted in the us-east-1 region. If you process these

Is there a way / tool to simulate Amazon's SimpleDB for the purpose of development? In my quest for above, I found this tool but this is for the Mac OS. Anything that can be installed on Win XP? Needless to say, all SimpleDB APIs need to be supported. Just in case it matters, mine is a .Net based web application. SimpleDB/dev runs on Windows, Linux and Mac. The Wareseeker.com page that you found has copied the information across incorrectly. The Google Code project page for the tool is here http://code.google.com/p/simpledb-dev/ The C# library ( http://developer.amazonwebservices.com/connect
