Exception and session handling with A4J

[icai]

I want to make use of following to handle the exception;

A4J.AJAX.onError = customFunction(req,status,message) {

 // Custom Developer Code

 };

A4J.AJAX.onExpired = function(loc,expiredMsg){

 // Custom Developer Code

};

Can someone please give any example of using above in JSP. Otherwise if possible please guide to some appropriate link.

Thanks in advance!!

It should be:

A4J.AJAX.onError = function(req,status,message) {

 // Custom Developer Code

 };

Dev Guide has an error there.
