Comparing dates

[jkleiser]

In our Seam web application we need to render certain elements in our xhtml pages only if the current date is after (or before) some specified date. We've tried things like this: deadlineDate.after(currentDate)
The problem with this is that our deadline dates typically have 00 hours (00:00:00), while currentDate is (I believe) down to the seconds. If deadlineDate is 05/20/2009 00:00:00, and currentDate is 05/20/2009 16:02:03, then the 'after' method returns false, and the effect is as if we've passed the deadline. What we really want is to compare a truncated currentDate against a (truncated) deadline. Is there a nice and easy way to do that?

That is not much a Seam related question ;)

Joda time library is pretty powerful with the dates handling.

Let me Google that for you . Was that so hard?

Please try this,

SimpleDateFormat sdf = new SimpleDateFormat ( "MM/dd/yyyy" ) ; 
Date beforeDate = sdf.format ( dateobjecttobecompared )  ) ; 
  
  
if  ( !beforeDate.before ( sdf.format (new java.util.Date ())))  
    return false; 

Thanks
