Passing Value from servlet to JSP file without RequestDispatcher

Question

Is it possible to pass value of variable from Servlet in to JSP. Say i have a JSP something like welcome.jsp and I have some variable initialized in welcome.java servlet.

When I run welcome.jsp it should take value from welcome.java and display it on page.

When I set the RequestDispatcher and forward it its still going to show the servlet URL.But I want the URL to be JSP file.But the Variable I display in JSP file should be taken from servlet.

You can archive it using session attributes.

.java

request.getSession().setAttribute("attrName", "value");

request is instance of javax.servlet.http.HttpServletRequest

.jsp

${attrName}

To get more about session attributes, read docs. You can set attribute of any type.

request.getSession().setAttribute("attrName", new ArrayList());

I am Sure your method works.But Storing Array in session is not a good Idea I guess.Sorry If I am Wrong. – Java Beginner Feb 11 '13 at 10:42
@user1973669, it is only right way to store user session data on server. – bsiamionau Feb 11 '13 at 10:46
You could also use request scoped attributes 'request.setAttribute();' if you don't need the passed values maintained on the session scope. – Waleed Almadanat Feb 11 '13 at 12:11

You can put the variable in Session and redirect the user to welcome.jsp page.
