title: redirect page invoked from java class
body: <p>Im new to java web app, JavaEE if I'm not mistaken. it happen that I was task to finished a certain project, while learning Java web app. So I'm not even certain if where am at is right. Here is the dilemma Im facing.</p>
  
  <p>It had a timer on a certain java class. based on the timer count, per couple of seconds, the page is suppose to redirect to another page. To explain further of what I want to achieve, refer to the following:</p>
  
  <p>user opens Page1
  after 30 mins redirects to Page2
  after 15 minutes redirects to Page3</p>
  
  <p>the timer is set on the java class and not on the jsp file.
  is there a way that the java class could issue a redirect command to the web browser?</p>
