validation at the data tier

[snowch]

I have a bean that is populated in another tier and sent to me via web services. I am responsible for verifying the bean before persisting it. I would like to use spring validation where I will be responsible for calling validate() on the Validator implementation and passing in an Errors implementation to the validate() call. What Errors implementation should I use? Should I create my own?

Thanks in advance...

I think I've found how to use the validator without the MVC framework:

BindException validatePersonWebServiceMethod(Person person) {

...
Validator validator = new PersonValidator();
BindException errors = new BindException(person, "target");
...
validator.validate(person, errors);
...
return errors;
}

The only thing I need to do is to work out how to send a BindException via. the webservice. Any suggestions?

Thanks in advance ...
