title: HTML5 drag and drop file upload to Java Servlet
body: <p>I am currently using Uploadify (Flash + Ajax) to the Servlet (Commons Upload with OWASP ESAPI overlay) with success, but I was wondering how I would go about building in HTML5 support, or rather HTML5 with Flash support.</p>
  <p>I know how to get the HTML5 drag and drop working, but I can't quite figure out the mechanics of a Java Servlet connection and/or backend.</p>
