public static com.sun.enterprise.admin.util.ValidatorgetInstance()

        return( sInstance );
public ValidatorResultvalidate(java.lang.Object object)
Validate the object by checking for non-null. It is expected that subclasses will override this behavior but may invoke super.validate() to make this check.
