Hello again
I just want to say that I managed to solve this problem without creating a
temporary , thanks to this thread :
http://old.nabble.com/(de)serializing-map%3Cconst-A*%3E-to5538474.html#a5596607<http://old.nabble.com/%28de%29serializing-map%3Cconst-A*%3E-to5538474.html#a5596607>

And here it is what I have got in my problem :

    boost::shared_ptr<const TT> jj(new TT(5));

    {
        boost::archive::xml_oarchive oa(ofs);
        oa & BOOST_SERIALIZATION_NVP(jj);
    }

    boost::shared_ptr<const TT> rjj;

    {
        void* xptr=&rjj;
        boost::shared_ptr<TT> *xxptr;
        xxptr=static_cast< boost::shared_ptr<TT> * > (xptr);
        boost::archive::xml_iarchive ia(ifs);
        ia & BOOST_SERIALIZATION_NVP(*xxptr);
    }
