How to access @ViewScoped managed beans from Servlets?
jsf, servlets, view-scope
Solution
That's not possible, no. The view scope is tied to a specific JSF view, which is no means of in a plain HTTP servlet request. Note that you can't access concrete request scoped beans during a plain HTTP servlet request either, they would always return `null`.
The session scope is the best what you can get. You can just remove the attribute from the session scope once you're finished with it in the servlet.
session.removeAttribute("somename");
Problem
I would like to access a view scope managed bean inside a Servlet. I searched for similar question and got these ones: how to get beans from view scope which uses `FacesContext.getCurrentInstance()`, inapplicable inside a Servlet because it should give a null result JSF - get managed bean by name which treats all other scopes but not viewscope I'm going to think it is not possible, is it ? There is the simple solution to change that bean scope to session scope but it is a last chance because I'm worried by memory consumption. My final need is the following: the managebean contains some data displayed in a dataTable. The same page should include the image (mandatory) of chart representation of those data. The image can be produced by a Servlet but it needs to access the data or reload them from the db. I also tried the `<p:graphicImage>` from PrimeFaces 2.X but it is not compatible with viewscope beans. Any suggestion?
