title: How to trace all methods run by a Struts2 Web Application?
body: <p>I need to make some change to a Java-EE Struts2 Web Application written by other developers.</p>
  
  <p>Since I don't know exactly how it works, I'd like to map all the actions and methods that are called on each request, to better understand the web application workflow before altering it.</p>
  
  <p>Is there a way to achieve this goal ?</p>
