I did this quite a while ago with

public class ImageTagUtil {
  public static String getName(HttpServletRequest request) {
    String command = null;
    String buttonValue = null;
    Enumeration enum = request.getParameterNames();

    while(enum.hasMoreElements()) {
      buttonValue = (String)enum.nextElement();
      if(buttonValue.endsWith(".x")) {
        command = buttonValue.substring(0,buttonValue.indexOf('.'));
    return command;

.  I just employed put it in SimpleDispatchAction to get the 
reflection.  If you do this with utils on the side, which seems like a 
good idea but not good enough to bloat Struts with to me, then you have 
to understand that this will not work for code that has used 
DispatchAction, LookupDispatchAction or MappingDIspatchAction, because 
those classes use different data.
