title: Why does my jar can't open from the task Scheduler
body: <p>I'm trying to start a jar after my login has proceeded.
  This action is performed by the Task Scheduler from Windows.
  When I run this jar from his own directory it works properly.
  When I'm logged in, the JVM gives me the following error:
  "Could not find main class" and the directory of my jar.
  I already set up the main class in the manifest.</p>
