Exception handling in jsr286 portlet

Question

I am trying to handle an exception in a spring portlet-based user interface application ,

I used spring globalexception handlingwith @ControllerAdvice.

It works fine in a servlet application, but does not work in a portlet application. I noticed that the spring container did not process @ControllerAdviceon the portlet. I tried searching the Internet for the same issue, but no luck.

Is there any other way to handle exceptions in portlet applications?

Thanks in advance.
