how can created date using backing bean when try print on console show null suggetions?

your date object null because never initialized. need do:

date createddate = new date(); 

this gives createddate actual date created value.

on small tangent, suggest using calendar when dealing dates. partly because date api flawed , deprecated.

calendar singleton object can used following:

calendar createddate = calendar.getinstance(); 

when creating object use current locale , timezone, unless specify otherwise.

hope helps!
