Question

Is it possible to retrieve session object stored by a servlet, in a JSP file? How do I do that?

Answer 1

You can use EL ${} in JSP to access objects in page, request, session and application scope by their attribute name. You just have to specify the same name as you used in the servlet to store the attribute. For example, when you store an User object with the attribute name "user" as follows

request.getSession().setAttribute("user", user);

then it’s available in the forwarded JSP by the same attribute name as follows

${user}

Another example if it has a name property with a getter:

<p>Welcome, <c:out value="${user.name}" /></p>
