Servlet session listener

Question

Hello Forum members,
I want to delete a directory on my server after the session has expired. The session has the directory path that I want to delete. <listener>/<listener-class> in web.xml listens for the session expiry. I implemented the following code (session listener) to do the job. This works fine when I deploy on Weblogic App server but does'nt work if I delpoy it on to TOMCAT.
What I am doing is getting the path of the directory from the session using session listener sessionDestroyed(HttpSessionEvent se)
once the session has expired and delete it. Is this the right of doing this or is there any other method that I can use?
public void sessionDestroyed(HttpSessionEvent se) {
          HttpSession session;
          File path;
     System.out.println("enter the sessionDestroyed method");
          try{
     session = se.getSession();
               if ( session != null ){
if ( (String)session.getAttribute( FILES_DOWNLOAD_PATH_ATTRIBUTE) != null ){
                    path = new File((String)session.getAttribute( FILES_DOWNLOAD_PATH_ATTRIBUTE));
                    FileUtils.deleteFilesInThisDirectory(path);
                    FileUtils.deleteDirectory(path);
          }catch(Exception exception){
               System.out.println("some problem in DeleteOnExit.sessionDestroyed() " + exception.toString());
System.out.println("exit the sessionDestroyed method");

try{
session = se.getSession();
if ( session != null ){
if ( (String)session.getAttribute( FILES_DOWNLOAD_PATH_ATTRIBUTE) != null ){
path = new File((String)session.getAttribute( FILES_DOWNLOAD_PATH_ATTRIBUTE));
FileUtils.deleteFilesInThisDirectory(path);
FileUtils.deleteDirectory(path);
}catch(Exception exception){
System.out.println("some problem in DeleteOnExit.sessionDestroyed() " + exception.toString());
System.out.println("exit the sessionDestroyed method");
