Invoke bean validation

Question

I am using JSF 2 ,myfaces, hibernate-validator-4.1.0.Final.jar.

I use hibernate-validator for validating values entered in form.

public class Client {
   @Persistent
   @Pattern(regexp = "|.+@.+\\.[a-z]+", message = "Email format is invalid.")
   private String email;
   //getter
}

I am developing bulk-upload module ,where i parse csv data and create database records.

...
try{
  Client cl=new Client();
  cl.setEmail("from_csv_data");
}catch( //validation failed

How do i reuse the same validator here?

Set> constraintViolations = validator.validate(nc);
throws this exception

SEVERE: Received 'java.lang.NoSuchMethodError' when invoking action listener '#{clientBean.bulkUpload}' for component 'j_idt86'

I tried this solution link
I have hibernate-jpa-2.0-api-1.0.0.Final.jar,hibernate-validator-4.1.0.Final.jar
Do I need any other jar to make this work?

Answer 1

You can invoke the validator manually with something like:

ValidatorFactory factory = Validation.buildDefaultValidatorFactory();

Validator validator = factory.getValidator();

Client client = new Client();

Set<ConstraintViolation<Client>> constraintViolations = validator.validate(client);
