title: Accessing the user from a liferay portlet?
body: <p>I'm attempting to develop a portlet for liferay.</p>
  
  <p>How can I get access to the username and password (and other data liferay has) of the user that's currently logged in?</p>
  
  <p>I'd also like to be able to execute some code when users change their password.</p>
