title: event java google app engine
body: <p>I just started using google app engine to develop a web application and I'm a little lost on how to deal with events sent from buttons properly.
  For some reason, when I try to use a JButton on my application I get this error. </p>
  
  <p>"javax.swing.JButton is not supported by Google App Engine's Java runtime environment"</p>
  
  <p>the only way I managed to get an on_click event so far was to use an html button and use a "post" or "get" requests.</p>
  
  <p>So, is their a tutorial somewhere to help me understand better how to use buttons and other components in my application?</p>
