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

Struts 2 Integer Validation

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?

Re: Custom validation with Struts2
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);
Remove this part above
this.setCardNo(tmpInt);
You don't have to do this, it will be done by Struts2
System.out.println(Card no (validation) = +
cardNo);
if (cardNo 1 || cardNo 99) {
addFieldError(cardNo, Must be int);
System.out.println(INPUT...);
}
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.

Re: Custom validation with Struts2
I'm not sure were is the problem but I've just checked such simple
example below and everything is ok. Maybe you should consider to use
Long instead of Integer, because when you enter more then 2147483647
to the field you will get some strange value back to the input
(because you loose precision ;-)
class EmployeeAction extends ActionSupport {
private Integer cardNo; // getter setter
public void validate() {
if (cardNo == null) {
addFieldError(cardNo, Should be integer!);
} else if ( cardNo 1 || cardNo 99) {
addFieldError(cardNo, Should be integer!);
}
}
}
JSP
s:textfield label=Card Number name=cardNo /

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.
