Question

In JSP page we can access to attributes using this: ${name}. But if we in sevlet do the following:

req.getSession.setAttribute("name", sessionName );
getServletContext().setAttribute("name", sevletContextName)
req.setAttribute("name", reqName);

then which variable JSP will access when use ?

${name}

Answer 1

The JSP EL looks in page, then request, then session, then application.

If you want to access the session explicitely, use

${sessionScope.name}

For the servlet context, use

${applicationScope.name}

(and similarly for pageScope and requestScope)
