Maybe you could write a custom implementation of java.text.Format or override java.text.NumberFormat to do it. I'm not aware of an API class that does such a thing for you.

Or you could leave that logic in the class that serves up the data and send it down with the appropriate format. That might be better, because the JSP should only care about formatting issues. The decision to display as "1000" or "1K" could be a server-side rule.
