Here is how you can put the request attribute and then get it.

    Map link = new LinkedHashMap();
    link.put("key", "value");
    //put map as request attribute 
    request.setAttribute("hash",link);
    //get map as request attribute from the request
    Map link1 =(Map)request.getAttribute("hash");

Hi buddy, i have tried this but i get an error saying Map link = new LinkedHashMap(); even though this hashmap works in all other classes .' It says can't understand Vehicle".. Vehicle is a class in the same project. – user8948414 Nov 16 '17 at 09:45
If trying to get attribute in jsp then make sure you import Vehicle class in jsp file using page directive. – Har Krishan Nov 16 '17 at 09:48
How can i do it ? Please if you could explain a bit it would be great thanks – user8948414 Nov 16 '17 at 10:16
In the top of jsp file add below: <%@ page import=".Vehicle" %> Use the proper package name of the class Vehicle – Har Krishan Nov 16 '17 at 10:21
Package name is default, so should i say .Vehicle – user8948414 Nov 16 '17 at 10:27
In that case just add : <%@ page import="Vehicle" %> – Har Krishan Nov 16 '17 at 10:36
Thanks buddy , you are a legend – user8948414 Nov 16 '17 at 10:36
Welcome, I hope it is working now. – Har Krishan Nov 16 '17 at 10:39
