how to send an object from a servlet to a jsp

[mosis]

I really need help ,
i am working on an application with netbeans and servlets.
I have a form in which i give the id then select a table in which i will go and search the id to the oracle database.


i am trying to send my objet to the jsp file from the servlet.
--------------------------------------------
this is the way i did

//recherche sur la table BASE_NGHLR new instance pour acceder a la methode recherche(id)
BASE_NGHLR base=new BASE_NGHLR();
//instance pour recuperer le resultat de la recherche (qui retourne un objet)

base=base.recherche(msisdn);
//envoi a la page res_recherche.jsp
request.setAttribute("BASE_NGHLR",base.getImsi());
RequestDispatcher res=getServletContext().getRequestDispatcher("/res_recherche.jsp");
res.forward(request,response);
------------------------------------------------------

this is my error
