I am developing a website with servlets and JSP.I want to know how to share data between a servlet and JSP as while searching I noticed that the getSession() method has been deprecated and currently I cannot add data to session for sharing the data.Please someone suggest me how should I share data between the servlets and JSP.
回答1:
We can apply two ways most probably
1 ) request
2 ) session
Examples :
request.setAttribute("userName", userName );
session.setAttribute("userName", userName );

in your body method doGet do something like that,
String value = "par1"
request.setAttribute("parameter", value);
your jsp file:
<%
String value= (String) request.getAttribute("parameter");
out.println(value);
%>
