[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Writing Hibernate validator

[waheed.murad]

I want to  have my own Hibernate annotaion validator...... named NotEmpty a problem is that when after form submition the only initialize() method is called. isValid() method does not executes......

below is the code and Thanks in advance for help......


------------- Annotation descriptor -------------------
import java.lang.annotation.Documented;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
import org.hibernate.validator.ValidatorClass;


@ValidatorClass(value=NotEmptyValidator.class)
@Target(value={ElementType.METHOD,ElementType.FIELD})
@Retention(value=RetentionPolicy.RUNTIME)
@Documented

public @interface NotEmpty {
	String message() default "Field cannot be empty";
}

------------- Annotation validator -------------------

import org.hibernate.validator.PropertyConstraint; 
import org.hibernate.validator.Validator;

import java.io.Serializable;

public class NotEmptyValidator implements Validator, PropertyConstraint, Serializable {
    
	
	public boolean isValid(Object value) {
    	     System.out.println(" is Valid method called...");
                     ..............
                     .............. 
      	     return false;
                  }

	public void initialize(NotEmpty parameters) {
              	      System.out.println(" Initialize method called...");
                }

                public void apply(org.hibernate.mapping.Property property){
        	     System.out.println(" Apply method called...");
                 }

}
