Hi All,
I have develop a SpringMVC-portlet and I am trying to generate three kind of report i.e. Web, PDF, Excel form. I am successful in generating Web Report but When I am trying to get PDF and Excel I am getting such exception: I am not understanding this ExceptionConvertor, If any hint is added here will be very wonderful for me.
Thank you
