Calling business methods in a FieldValidatorSupport extended class

[Alceu Medeiros <al...@gmail.com>]

Hi,

I'm using Struts 2, JPA and Spring 2 and I want to check if an e-mail
address is already in use in my app, but I want to make it implementing a
custom validator and so it may be solved as a fieldError.

My strategy is that in my UserEmailValidator I have an object of class
UserBusiness as a attribute who says me if the e-mail is already in use or
not, and Spring 2 injects the dependency for me. The problem is that my
business attribute in UserEmailValidator class is coming with null value
because Spring2 didn't make the injection of dependency. This is the code
involving the problem:


spring.xml
- - -

(...)

<bean id="userBusiness" class="v1c2.business.impl.UserBusinessImpl"
parent="crudBusiness" scope="singleton">
    <property name="dao" ref="userDao" />
</bean>

(...)

<bean id="userEmailValidator" class="v1c2.validator.UserEmailValidator"
scope="prototype">
    <property name="business" ref="userBusiness" />
</bean>

(...)

- - -


UserEmailValidator.java
- - -

package v1c2.validator;

import v1c2.business.UserBusiness;
import v1c2.pojo.User;

import com.opensymphony.xwork2.validator.ValidationException;
import com.opensymphony.xwork2.validator.validators.FieldValidatorSupport;

public class UserEmailValidator extends FieldValidatorSupport {

    private UserBusiness<User> business;

    public void validate(Object object) throws ValidationException {
        String email = (String) getFieldValue(getFieldName(), object);

        if (business.isEmailInUse(email)) {
            addFieldError(getFieldName(), object);
        }
    }

    public void setBusiness(UserBusiness<User> business) {
        this.business = business;
    }

}

- - -

Is this the right strategy? I'm not too sure because Spring isn't making its
work. How can I call a business' method in a FieldValidatorSupport extended
class?

Can anyone help me, please?
