Adding more than one validation to form field

[shaf maff]

Hi Guys

I am using the actionClass-validation.xml method to validate form inputs. I have one field which I want to valid several things, the first I have already implemented and that is if the field is empty. The other two validations I want to implement are (1) Length of string, it must be 11 chars and (2) All chars must be numbers only. Here is what I have done so far:

actionClass-validation.xml

<validators>
    <field name="contactno">
        <field-validator type="requiredstring">
            <message>Your Contact Number is required</message>
        </field-validator>
    </field>
</validators>

actionClass.java

public String execute() throws Exception {
if (isInvalid(getContactno())) return INPUT;
return SUCCESS;
}
private boolean isInvalid(String value) {
return (value == null || value.length() == 0);
}

hello...just try out this piece of coe for validator xml file.I'm sure the string length validator would work fine not sure of the int validator.Give a try.

<validators>    
<field name="contactno">        
<field-validator type="requiredstring" short-circuit="true">            
<message>Your Contact Number is required</message>        
</field-validator>

 <field-validator type="stringlength" short-circuit="true">
  <param name="minLength">11</param> 
  <param name="maxLength">11</param> 
  <message>Your Contact Number must be 11 characters!</message>
</field-validator>
<field-validator type="int" short-circuit="true">
  <param name="min">0</param> 
  <message>Enter a valid Contact Number!</message>
</field-validator>  
    
</field>
</validators>

You can do the same without the short-circuit attribute also.

Hi
The max char works perfectly fine, but the int one doesn't work at all. If I enter letters it will still work when it shouldnt. And if I submit it the action class spits out the following error:

javax.servlet.ServletException: java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.String
org.apache.struts2.dispatcher.Dispatcher.serviceAction(Dispatcher.java:515)
org.apache.struts2.dispatcher.FilterDispatcher.doFilter(FilterDispatcher.java:422)

I tried to convert the value from int to string before storing it but everytime I would submit the form the contactno field would just turn blank.

I have managed to fix it. I used regex instead and that did the job.
