title: Recognizing properties file changes without restarting Tomcat
body: <p>Is there any way for the server to recognize the changes without restarting after a properties file updated? Because it causes Java.lang.OutOfMemoryError: PermGen space after the second restart.</p>
  
  <p>The properties file is under Web-Inf folder.</p>
  
  <p>Cheers...</p>
