import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts2.interceptor.ServletRequestAware;
import org.apache.struts2.interceptor.ServletResponseAware;

public class MyAction extends ActionSupport implements ServletResponseAware, ServletRequestAware {

  protected HttpServletResponse servletResponse;
  @Override
  public void setServletResponse(HttpServletResponse servletResponse) {
    this.servletResponse = servletResponse;
  }

  protected HttpServletRequest servletRequest;
  @Override
  public void setServletRequest(HttpServletRequest servletRequest) {
    this.servletRequest = servletRequest;
  }
}

public String execute() {
  int division;

  // Save to cookie
  Cookie div = new Cookie("division", String.format("%d",division));
  div.setMaxAge(60*60*24*365); // Make the cookie last a year!
  servletResponse.addCookie(div);
  
  // Load from cookie
  for(Cookie c : servletRequest.getCookies()) {
    if (c.getName().equals("division"))
      division=Integer.parseInt(c.getValue());
  }

  return "success";
