unique field validation

[Nathan Coast <na...@codeczar.com>]

Hi,

Is there a standard way to handle validations that can only occur 
server-side?  e.g. unique fields.

I'm guessing you don't have to include the unique validation in any of 
your validation configuration.

Is it simply a case of overriding the validate method in my action form?

public ActionErrors validate(ActionMapping mapping, 
       HttpServletRequest request)
{
   ActionErrors errors = super.validate();

//  do my custom validation

   return errors;
}

cheers
Nathan

I think this kind of validation has to be done in the business logic, behind
struts.
Neither in the action form, nor in the action. 

The business logic should throw appropriate exception, which then can be
handled by struts part of the application.

Leon
