hi
i am doing client side validations i have made all necessary changes in my project in jsp i have included

In my validation.xml i have defined all validation
validator.xml is also updated

Message Resources all 3 files

my action class & form class are also changed but still on running my form
it shows me following error

No form found under 'userLoginForm' in locale 'en_US'. A form must be defined in the Commons Validator configuration when dynamicJavascript="true" is set.

Please help

thanks in advance

Hey ...
make sure that form class is extends validatorForm and in validation.xml check the formname <form name="xxxx"> should be same in struts-config.xml
and <html:javascript formName="xxxx" />

<html:form action="/ yyyy.do " onsubmit="validatexxxx(this);">

<!--
  $Id: validator-rules.xml,v 1.1.2.1 2006/07/01 20:50:46 eugene-proddev Exp $

This file contains the default Struts Validator pluggable validator
   definitions.  It should be placed somewhere under /WEB-INF and
   referenced in the struts-config.xml under the plug-in element
   for the ValidatorPlugIn.

<plug-in className="org.apache.struts.validator.ValidatorPlugIn">
        <set-property property="pathnames" value="/WEB-INF/validator-rules.xml,
                                                  /WEB-INF/validation.xml"/>
      </plug-in>

These are the default error messages associated with
   each validator defined in this file.  They should be
   added to your projects MessageResources.properties
   file or you can associate new ones by modifying the
   pluggable validators msg attributes in this file.

# Struts Validator Error Messages
   errors.required={0} is required.
   errors.minlength={0} can not be less than {1} characters.
   errors.maxlength={0} can not be greater than {1} characters.
   errors.invalid={0} is invalid.

errors.byte={0} must be a byte.
   errors.short={0} must be a short.
   errors.integer={0} must be an integer.
   errors.long={0} must be a long.
   errors.float={0} must be a float.
   errors.double={0} must be a double.

errors.date={0} is not a date.
   errors.range={0} is not in the range {1} through {2}.
   errors.creditcard={0} is an invalid credit card number.
   errors.email={0} is an invalid e-mail address.

Note: Starting in Struts 1.2.0 the default javascript definitions have
         been consolidated to commons-validator. The default can be overridden
         by supplying a <javascript> element with a CDATA section, just as
         in struts 1.1.

hi aditi.....
it has to work..
check this onces
<html:form action="/userLogin" onsubmit="return validateuserLoginForm(this);">

after changing the above line .run the jsp and check the generated source code in the browser of the userLogin.
you can find the generated javascript.
if it is coming means javascript is working..

Hi aditi

did you kept this inside <head> tag

<html:form action="/userLogin" onsubmit="return validateuserLoginForm(this);">

</head>

onces it is done . run the jsp in the browser. ie or mozilla.

after that check viewsource of your jsp .
you can find the generated javascript ..
