title: from a java application running in a citrix session, how to know if the client workstation is idle?
body: <p>we are currently developing java applications that run in a citrix environment. We need to react when the user is idle for a while. </p>
  
  <p>The problem is that if the user is active outside the citrix application, say, for example, in a winword started locally on the client, how could we know it from the application in the citrix session.</p>
  
  <p>We tried jna, that works perfectly if started locally. But in the citrix session, that does not work...</p>
  
  <p>Any idea ?</p>
