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.reche rche(msisdn);
//envoi a la page res_recherche.j sp
request.setAttr ibute("BASE_NGH LR",base.getIms i());
RequestDispatch er res=getServletC ontext().getReq uestDispatcher( "/res_recherche.j sp");
res.forward(req uest,response);
------------------------------------------------------

this is my error
