String value substitution

[nachagoni rishi]

Is there any way i can replace "ticketNumber==null" and "plateNumber==null" with value of errorField, so that my code is shorter.


public ActionErrors validate(
ActionMapping mapping,
HttpServletRequest request) {

ActionErrors errors = new ActionErrors();

HttpSession session = request.getSession();
String errorField = (String) session.getAttribute("errorField");
if (errorField.equalsIgnoreCase("ticketNumber")) {

if ((ticketNumber == null) || (ticketNumber.trim().length() == 0))
errors.add(errorField,new ActionError("error." + errorField + ".null"));
}
if (errorField.equalsIgnoreCase("plateNumber")) {
if ((plateNumber == null) || (plateNumber.trim().length() == 0))
errors.add(errorField,new ActionError("error." + errorField + ".null"));
}

return errors;
}

import the GenericValidator class and use the isBlankOrNull method.
