how to use oval on custom validation Annotation - validation

Question

Here is my code for creating a custom Annotation for validating Name
ValidName.java
package custom.Annotation;
import java.lang.annotation.*;
import net.sf.oval.configuration.annotation.Constraint;
#Documented
#Retention(RetentionPolicy.RUNTIME)
#Target(ElementType.LOCAL_VARIABLE)
#Constraint(checkWith=NameValidator.class)
public #interface ValidName {
String message() default NameValidator.message;
}
here is my code for Constraint Class
package custom.Annotation;
import net.sf.oval.Validator;
import net.sf.oval.configuration.annotation.AbstractAnnotationCheck;
import net.sf.oval.context.OValContext;
import net.sf.oval.exception.OValException;
import play.Logger;
import java.util.regex.Pattern;
public class NameValidator extends AbstractAnnotationCheck<ValidName>
{
public final static String message="custom.message";
private static final String letter = "[a-zA-Z]";
public static final Pattern VALID_PATTERN = Pattern.compile(letter);
public static boolean isValidText(String userName) {
return VALID_PATTERN.matcher(userName).matches();
}
#Override
public void configure(ValidName annotation) {
setMessage(annotation.message());
}
#Override
public boolean isSatisfied(Object validatedObject, Object valueToValidate, OValContext context,
Validator validator) throws OValException {
try
{
if (valueToValidate == null) {
return false;
}
}catch (Exception e){
e.getMessage();
}
return` isValidText(valueToValidate.toString()`);
}
}
When I applied #ValidName to any local variable nothing happened
and I also am unable to debug the program. Any suggestions?

You need to use the oval validation by calling validate method of oval validation library.
#Autowired
#Qualifier("ovalValidator")
private Validator ovalValidator;
List<ConstraintViolation> violations = null;
violations = ovalValidator.validate(objectToValidate);
