How to access Hibernate Validation declarations in Facelet or JSP for JavaScript validation?

[bharathiya]

I am using LiveValidation javascript validation tool for client side validation of the Seam-Facelet application. On the server side, I am using hibernate validation.

But, I want to use the hibernate validation declaration information (like minimum length, max length etc.) in the javascript.

Thanks,

Seam takes care of the (java-script) interaction with you domain model using Ajax. The big advantage is that you concentrate the validation on the domain-layer and you don't need to copy validation again in the presentation layer. The disadvantage is that it needs interaction with the server, but with present Internet-speed that shouldn't be a point anymore.

Look at the s:validate tags in the Seam documentation.

We are planning to use the client side validation using the LiveValidation to reduce both the server round-trip and the load on server.

So I am still looking for ways to access the hibernate declared validations into the javascript validation.

Also, not able to get the JavaScript alert messages as the loacalised ones.
I tried 2 ways:
1.First way:  

<f:verbatim>

<script language="javascript">
var firstNameFl= new LiveValidation('course:firstNameFld:firstName');
firstNameFl.add(Validate.Length, {minimum: 10, failureMessage: "Length must be minimum 10"});
firstNameFl.add(Validate.Presence, {failureMessage: "Please enter a valid First Name....", validMessage: "ddf"});
LiveValidation('course:lastNameFld:lastName');


var dobFld= new LiveValidation('course:dobFld:dob');
//This is the attempt to alert some message from the resource bundle
alert("message from resource bundle: " + #{messages[emailErrorMessage]});                                           
</script>
</f:verbatim>

2. Second way: By using an intermediate js file with localised values in it:

messages.js file

emailErrorMessage=#{messages[emailErrorMessage]};

And then, using this in the LiveValidation:

<f:verbatim>
<script language="javascript">
var firstNameFl= new LiveValidation('course:firstNameFld:firstName');
firstNameFl.add(Validate.Length, {minimum: 10, failureMessage: "Length must be minimum 10"});
firstNameFl.add(Validate.Presence, {failureMessage: "Please enter a valid First Name....", validMessage: "ddf"});
var dobFld= new LiveValidation('course:dobFld:dob');
alert("message from resource bundle: " + emailErrorMessage );                                       
                                            </script>
                                        </f:verbatim>

Please suggest.
