title: JSP page shows fine in Eclipse preview, but shows blank page when run on server
body: <p>I have a <code>login.jsp</code> page wich includes ExtJS code. </p>

  <p>When I click <em>Preview</em> tab in Eclipse, then it works correctly and I can see the output of the page.</p>

  <p>However, when I run the project on server, then I don't see anything, only a blank page. How is this caused and how can I solve it?</p>
