Thank you very much,
I guess i can return the String "IllegalDateRangeException" when
throwing that exception from my Service and check for that in my
onFailure class.
public void onFailure( Throwable caught )
{
if ( caught.getMessage().contains
( "IllegalDateRangeException" ) )
//handle my class.
}
Thnak you,
Satya
