Struts2 Validation using XML not working?

I'm trying to use Struts2 validation using XML to check various fields entered by Customer. My struts.xml extends struts-default, and I have a extremely simple action class TestAction which extends ActionSupport, but it is not working.

If anyone is able to help me see what I lack, I would be extremely grateful.

Here's what I have:

CustomerAction-validation.xml

<?xml version="1.0" encoding="UTF-8"?>

  <!DOCTYPE validators PUBLIC "-//Apache Struts//XWork Validator 1.0.2//EN" "http://struts.apache.org/dtds/xwork-validator-1.0.2.dtd">
<validators>
    <field name="customerName">
        <field-validator type="requiredstring">
            <message>Required</message>
        </field-validator>
    </field>
</validators>

struts.xml

<action name="addCustomer" class="com.yell.hibu.action.CustomerAction"
            method="execute">
            <interceptor-ref name="validation"/> 
             <param name="excludeMethods">  
                    input,back,cancel,browse  
                </param>
            <interceptor-ref name="fileUpload">
                <param name="maximumSize">2097152</param>
                <param name="allowedTypes">
                    image/png,image/gif,image/jpeg,image/pjpeg
                </param>
            </interceptor-ref>
            <interceptor-ref name="defaultStack"></interceptor-ref>
            <result name="success">/success.jsp</result>
            <result name="input">/registration.jsp</result>
        </action>

Here I have Registration.jsp for only 1 field

<s:form action="addCustomer" id="register-form" method="post"  validate="true" theme="xhtml" enctype="multipart/form-data">
<s:actionerror/>
<s:fielderror/>
<s:textfield name="customer.customerName" label="Customer Name:" cssClass="tooltip"  title="Max 10 characters allowed." maxlength="10"/>

Your

<interceptor-ref name="validation"/>

is self-closed, then the 

<param name="excludeMethods">  
        input,back,cancel,browse  
</param>

will never be read.

Validation Interceptor should run after Params Interceptor, as shown in the examples from the documentation.

Again, according to the documentation,

This interceptor is often one of the last (or second to last) interceptors applied in a stack, as it assumes that all values have already been set on the action.

Then, try to do like this:

<action name="addCustomer" class="com.yell.hibu.action.CustomerAction" 
        method="execute">

    <interceptor-ref name="defaultStack"></interceptor-ref>

    <interceptor-ref name="validation"> 
        <param name="excludeMethods">  
            input,back,cancel,browse  
        </param>
    </interceptor-ref>

    <interceptor-ref name="fileUpload">
        <param name="maximumSize">2097152</param>
            <param name="allowedTypes">
                image/png,image/gif,image/jpeg,image/pjpeg
            </param>
    </interceptor-ref>

    <result name="success">/success.jsp</result>
    <result name="input">/registration.jsp</result>
</action>

If it does not work, post your JSP and Action too.

Hope that helps
