Re: Custom validation with Struts2
If Integer Range Validator does not work for you then you shoud consider
regular expression validation for same, its can be done by restricting
number of digits and allowing only numeric characters.
Here is an example of similar problem

You may also want to consider declarative validation [1], either using
an XML file or annotations. Struts has built-in support for validating
an integer input is in a given range [2].
As to the problem of getCardNo() always returning 0, that shouldn't
happen; you may have a conversion error happening, or perhaps something
else is mis-configured somewhere. Struts should call setCardNo() for you
to pass the form data in.

That's all you have to have in your validate() method (if cardNo has
getter and setter defined in action class)
Remove also validate=true from your form, because you don't use client
side validation.

Custom validation with Struts2
Hello everybody,
I need to validate only 1 field on the jsp. It value should be between 1 and
99. Initially I started to implement through int validation but it seemed
to go wrong - it works with some limitation - maximum value should not exceed
1000 or something like that. I am trying to implement validation through
overriding validate() method. I use tiles together with Struts 2.0.11. I could
not tune it to work correctly. Could someone help, please?
Here are my snippets:
Struts.xml:
WTT_CARDS_EDITOR
def_page_employee_card
def_page_employee_card
Jsp:
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
JAVA Action:
public void validate() {
request = ServletActionContext.getRequest();
String tmp = "";
try {
tmp = request.getParameter("cardNo");
Integer i = this.getCardNo();
if (tmp != null && tmp.length() > 0) {
int tmpInt = Integer.parseInt(tmp);
this.setCardNo(tmpInt);
System.out.println("Card no (validation) = " + cardNo);
if (cardNo < 1 || cardNo > 99) {
addFieldError("cardNo", "Must be int");
System.out.println("INPUT...");
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
Thanx a lot.
Best regards, Filippov Andrey
