title: Edit Spreadsheets at Google Drive with Gdata (Java)
body: <p>I am trying to edit a public spreadsheet (key = 0Av4aUydPYoNAdHV2MnRaSFhrY0NSZnNOS28yTlhRTVE) on my google_drive using Java and gdata api, but without success.
  I change the url from <a href="https://spreadsheets.google.com/feeds/worksheets/key/private/full" rel="nofollow">https://spreadsheets.google.com/feeds/worksheets/key/private/full</a> to <a href="https://spreadsheets.google.com/feeds/worksheets/0Av4aUydPYoNAdHV2MnRaSFhrY0NSZnNOS28yTlhRTVE/private/full" rel="nofollow">https://spreadsheets.google.com/feeds/worksheets/0Av4aUydPYoNAdHV2MnRaSFhrY0NSZnNOS28yTlhRTVE/private/full</a> , but returns:</p>
  
  <blockquote>
    <p>Exception in thread "main" com.google.gdata.util.InvalidEntryException: Bad Request</p>
  </blockquote>
  
  <p>What does this mean?</p>
