ActionErrors or ActionMessages?

each action class or in the hander?

Thanks for help!

  In 1.2.7 you simply change the ActionErrors to ActionMessages. you still save 
the errors with the saveErrors method and it works the same in the tags.

              Exception - General Question 
              
       

  Hi everybody,

  Up to now, I was handling my exceptions in my Action class as follow :

  ----------------------------------------------------------------------------
  ----------------
     ActionErrors errors = new ActionErrors();
     try{
     ......
     ......

     } catch (Exception e) {
     //Put print stack trace in System.err so it is logged
     e.printStackTrace(System.err);
     //
     errors.add(ActionErrors.GLOBAL_ERROR, new
  ActionMessage("errors.keyDescribingError : "+e.getMessage()));
     saveErrors(request, errors);
     // Forward control to the appropriate error page
     forward = mapping.findForward("erreur");
     }
  ----------------------------------------------------------------------------
  ----------------


  However ActionErrors is now deprecated so I'm wondering if using
  ActionMessages instead is well appropriate.????

  I have seen that a common use is to define an ExceptionHandler....seems to
  be nice as we just handke the errors in one place but :
     - It seems that using ExceptionHandler we lost the finest degree of the
  exception and we have not a personnalized message for the exception thrown.
        Of course, we could do a catch in the Action class and throw the
  exception with the personalized messaged but then I have another question :
             - Does ExceptionHandler slower than catching the exception in
  each Action class?

  Finally, What is the best practice to handle exceptions in struts?

  Thanks in advance for your help
