[jboss-user] [JBoss Seam] - Problem in writing own annotation in seam

[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..."); 
} 

}
