Jiri,
 I have logic that does this.  Add this to your validator-rules.xml:
<validator name="twoFieldsEqual" classname="com.yourcompany.StrutsValidator"
method="validateTwoFieldsEqual" msg="errors.twoFieldsEqual"
depends="required" methodParams="java.lang.Object,
                 org.apache.commons.validator.ValidatorAction,
                 org.apache.commons.validator.Field,
                 org.apache.struts.action.ActionErrors,
                 javax.servlet.http.HttpServletRequest">
        <javascript><![CDATA[
           function validateTwoFieldsEqual(form) {
               var isValid = true;
               var focusField = null;
               var i = 0;
               var fields = new Array();
               oTwoFields = new twoFieldsEqual();
               for (x in oTwoFields) {
                   var field = form[oTwoFields[x][0]];
                   var secondField = form[oTwoFields[x][2]("equalField")];
                   if (field.type == 'text' ||
                    field.type == 'textarea' ||
                    field.type == 'select-one' ||
                       field.type == 'radio' ||
                    field.type == 'password') {
                          //alert('field is ' + field + ' and field value
is ' + field.value);
                          //alert('field2 is ' + field2 + ' and field2
value is ' + field2.value);
                          var value;
                          var secondValue;
                    // get field's value
                    if (field.type == "select-one") {
                             var si = field.selectedIndex;
                             value = field.options[si].value;
                             secondValue = secondField.options[si].value;
                    } else {
                             value = field.value;
                             secondValue = secondField.value;
                    }
                       if (value != secondValue) {
                           if (i == 0) {
                               focusField = field;
                           }
                           fields[i++] = oTwoFields[x][1];
                           isValid = false;
                       }
                   }
               }
               if (fields.length > 0) {
                  focusField.focus();
                  alert(fields.join('\n'));
               }
               return isValid;
           }]]></javascript>
</validator>
and this to your validation.xml:

<field property="password2" depends="required, twoFieldsEqual">
           <arg0 key="prompt.password2"/>
           <arg2 key="prompt.password"/>
           <var>
              <var-name>equalField</var-name>
              <var-value>password</var-value>
           </var>
</field>
and a method like this in your StrutsValidator class:

public static boolean validateTwoFieldsEqual(Object bean, ValidatorAction
va, Field field,
     ActionErrors errors, HttpServletRequest request)
  {
     String value = ValidatorUtil.getValueAsString(bean,
field.getProperty());
     String sProperty2 = field.getVarValue("equalField");
     String value2 = ValidatorUtil.getValueAsString(bean, sProperty2);
     if (!GenericValidator.isBlankOrNull(value))
     {
        try
        {
           if (!value.equals(value2))
           {
              errors.add(field.getKey(),
              Resources.getActionError(request, va, field));
              return false;
           }
        } catch (Exception e)
        {
           errors.add(field.getKey(),
           Resources.getActionError(request, va, field));
           return false;
        }
     }
     return true;
  }
