title: How to implement AWS signed requests with amazon java library?
body: <p>We're currently using amazon-a2s-2007-10-29-java-library.jar to interact with the Amazon Webservices or Product Advertising API, respectively.</p>
  
  <p>We don't see a way how to implement signed requests (mandatory from Aug 15) using this library, nor can we find an updated version supporting signed requests.</p>
  
  <p>There does not seem to be too much discussion about this topic around, thus I suspect we're either the only ones using this lib, or otherwise just too blind to see an obvious solution for the problem.</p>
  
  <p>I'd be happy for any hints on this. Thanks a lot in advance.
