  <p>I am trying to debug from eclipse, and I am new at this, but I can't understand why I get 404 at te default http post, or 500 if I call /VAADIN/ instead. What ever I do, I don't get the result of the code. Vaadin doesn't say much so I go around with numerous sites about gwt...</p>
  
  <p>On the contrary, if I do it in firefox, with /VAADIN/ I get some descent view.
  does anyone have a clue what should be my address url to point correctly with this web.xml?</p>
  
  <p>or...what should be a descent setup for web.xml. 2 days I can't go further than that :-(</p>
