On the server-side, use an expression validator to ensure the input 
contains only valid characters.

On the client-side either:
 - use ajax validation; or
 - use a javascript function that listens for the keypress event and 
rejects invalid keystrokes

As usual, the javascript keypress event on IE is different from all 
other browsers so the function has to include browser detection.
Here is the gist of what you need:

<s:textfield name="x" onkeypress="filterKeypress()" ...>

javascript:
function filterKeypress(e) {
  var accept = /[\d|\+|\-|\.]/;   // a regex pattern of accepted chars
  var keyChar;
  if (msie) {  // use your favourite broswer detection function
     keyChar = String.fromCharCode(e.keyCode);
  } else {
    keyChar = String.fromCharCode(e.which);
  }
  // check if the character is acceptable
  if (!accept.test(keyChar)) {
      e.preventDefault();   // if it's not, prevent the keypress event 
from proceeding
  }
}
