Hi
I am trying to use Validator in my application and can not get it to work. I
have a single test form that I would like to use the Validator for
client-side and server-side validation. If I add the following
<%@ taglib uri="/WEB-INF/struts-validator.tld" prefix="validator" %>
reference to the taglib to the test form JSP page, when I access this JSP
page after deploying the application, I get a NoClassDefFoundError exception
thrown (see full message at the end of this email). If I remove the taglib
reference, I don't get the error but the validation rules don't get applied
either.
The latest version of the struts-validator.jar file and the
struts-validator.tld files are in the WEB-INF/libs directory.
Thanks in advance for any help received.
============================================================
My web.xml file is defined as follows:
.....
<servlet>
<servlet-name>validator</servlet-name>
<servlet-class>com.wintecinc.struts.action.ValidatorServlet</servlet-class>
<init-param>
<param-name>config</param-name>

<taglib>
<taglib-uri>/tags/struts-validator.tld</taglib-uri>
<taglib-location>/WEB-INF/struts-validator.tld</taglib-location>
</taglib>

My Validation.xml file is defined as below:
<form-validation>

form[oRequired[x][0]].type == 'textarea' || form[oRequired[x][0]].type ==
'select' || form[oRequired[x][0]].type == 'radio' ||
form[oRequired[x][0]].type == 'password') && form[oRequired[x][0]].value ==
'') {
if (i == 0)
focusField = form[oRequired[x][0]];
fields[i++] = oRequired[x][1];
bValid = false;

if (fields.length > 0) {
focusField.focus();
alert(fields.join('\n'));
