[Boost-users] boost::serialization - trying to serialize derived class and base class.

I am writing a packet base class that can be serialized. The class so  
far looks like:

     class packet_base
     {
         using namespace boost;

         public:
             packet_base();
             ~packet_base();

             friend class boost::serialization::access;
             template <typename Archive>
             void serialize(Archive & ar, const unsigned int version)
             {
                 ar & m_length;
                ar & m_type;
                ar & m_method;
             }

         private:

             uint16_t m_length;
            uint16_t m_type;
            uint16_t m_method;
     };

The question now is how can I derive class A from packet_base and have  
both packet_base and A's variables serialized? Obviously base_class  
needs to be archived first so it's variables are at the front of the  
buffer.

Thanks in advance.
