struts2 validation not working

[Shilpa Tendulkar]

Hi
I'm new to struts2. I want to validate whether certain record exist in the DB or not. Now I dont have just a single field to validate to check duplicate record but I need to check complete recored with comibination to say data is duplicated.
What I mean is, optionId should have unique key value pair. there can be multiple key value pairs for one optionId. i'm using actionvalidation.

[b]validators.xml[/b]
<validators>  
  <validator name="DuplicateValueValidator" class="com.optionmanagement.web.support.DuplicateValueValidator"/>
</validators>
<b>Support.xml</b>
 <bean id="ValueValidator" abstract="true" class="com.optionmanagement.web.support.ValueValidator">
        <property name="ValueService" ref="valueService"/>
    </bean>
</beans>
[b]ValueValidator.java[/b]
public abstract class ValueValidator  extends FieldValidatorSupport {
  private OptionValueService valueService;

   public void validate(Object object) throws ValidationException {
    Object fieldValue = getFieldValue(getFieldName(), object);
    if (object instanceof OptionValueBean) {
      OptionValueBean l_value = (OptionValueBean) object;
      validateOptionValue(l_value, object);
    }
    else if(fieldValue instanceof OptionValueBean) {
      OptionValueBean l_user = (OptionValueBean)fieldValue;
      validateOptionValue(l_user, object);
    }
  }

  protected abstract void validateOptionValue(OptionValueBean l_value, Object p_object);

    /**
     * @return the valueService
     */
    public OptionValueService getValueService() {
        return valueService;
    }

    /**
     * @param valueService the valueService to set
     */
    public void setValueService(OptionValueService valueService) {
        this.valueService = valueService;
    }
}
[b]DuplicateValueValidator[/b]
public class DuplicateValueValidator extends ValueValidator {


  @Override
  protected void validateOptionValue(OptionValueBean p_value, Object p_object) {

      //check if key value pair already exists for given optionId
      OptionValueBean l_valueInDB = getValueService().findOptionValue(p_value);

      if( (l_valueInDB!=null && l_valueInDB.getOptionId()==p_value.getOptionId()) &&
              l_valueInDB.getOptionKey().equals(p_value.getOptionKey()) &&
              l_valueInDB.getValue().equals(p_value.getValue()) ){

        addFieldError(getFieldName(), p_object);
      }
  }
