jsf 2 - Writing Javascript for client-side class-level validation using primeface -

i have class-level constraint on class below:

@notequalaccounts public class fundtransfervo extends signablevo implements serializable{     private string fromaccount;     private string toaccount;     //setter,getter } 

and custom constraint code is:

@target({elementtype.type}) @retention(retentionpolicy.runtime) @constraint(validatedby = notequalaccountsvalidator.class) @clientconstraint(resolvedby=clientnotequalaccountsvalidator.class)   public @interface notequalaccounts {      string message() default "{org.javaee7.validation.custom.constraint.notequalaccounts}";      class<?>[] groups() default {};      class<? extends payload>[] payload() default {}; } 

i want have javascript client-side validation of class using primeface, i've written code below, doesn't work

primefaces.validator['notequalaccounts'] = {                    message_id: '...',       validate: function(element, fundtransfercontroller) {       if(fundtransfercontroller.fundtransfervo.gettoaccount()===fundtransfercontroller.fundtransfervo.getfromaccount()) {                   msg = '';                  throw msg;          }      }   };   

fundtransfercontroller controller bean(fundtransfervo) used in it.

is there way validate class-level constraints on client-side using primeface?
