servlet not forwarding session attribute to jsp

Question

Using embedded tomcat, this code works:

Servlet:

String test = \"test\";
request.setAttribute(\"test\", test);
request.getRequestDispatc         


        

Answer 1

You may want to compare the session id in the servlet and the jsp. If they are different maybe check your session and cookie configuration in tomcat

Answer 2

On the JSP side, you don't need to say request.getSession(), just session.getAttribute();
And you had a problem in your Main.java when creating the servlet context (a trick of using embedded Tomcat); you were not getting the context created by adding the webapp to tomcat, you had some other context.

//          File base = new File("src/main/webapp");
//          context = tomcat.addContext("", base.getAbsolutePath());
//          tomcat.addWebapp(null, "/", base.getAbsolutePath());

        context = tomcat.addWebapp("/", new File("src/main/webapp").getAbsolutePath());
        context.setSessionTimeout(10080);

I commented out your code and changed the context handling and now things work. And a new exception to be caught.

        } catch (ServletException | InterruptedException | LifecycleException exception) {
