Make sure your text field is defined inside an HTML form. Make sure
you have proper taglib directives on top of your JSP page, for

Get an HTTP sniffer and see what is sent from browser when you submit
a form. If you use Firefox, get Live HTTP Header extension.

I submit the textfield, and I used System.out.println

I got a blank. Therefore, something must go wrong.
