[jboss-jira] [JBoss JIRA] Resolved: (JBAS-4303) Web session is empty when forwarding request to another web context.

[Remy Maucherat (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBAS-4303?page=all ]

Remy Maucherat resolved JBAS-4303.
----------------------------------

    Resolution: Rejected

The session object is not shared across web applications, so your two sessions contain a different set of attributes. Your workaround is a reasonable: it will make your application portable.

> I have following in web.xml:
> =====================
>     <servlet>
>         <servlet-name>Redirector</servlet-name>
>         <servlet-class>web.servlet.Redirector</servlet-class>
>     </servlet>
>     <servlet-mapping>
>         <servlet-name>Redirector</servlet-name>
>         <url-pattern>/redirect.do</url-pattern>
>     </servlet-mapping>
>     <error-page>
>         <error-code>404</error-code>
>         <location>/redirect.do</location>
>     </error-page>
> =====================
> It is located in /deploy/web.jar. It is deployed under / context.
> My jsp are in dir: /deploy/resources.war/, deployed under /resources.
> In Redirector I do:
> ==============
>         String url = (String) request.getAttribute("javax.servlet.error.request_uri");
>         String contextPath = (String) context.getAttribute("/resources");
>         ServletContext c = context.getContext(contextPath);
>         RequestDispatcher disp = c.getRequestDispatcher(url);
>         disp.forward(request, response);
> ==============
> So now I can reach my jsp in another context.
> In servlet Login I do:
> =============
>     ClientManager manager = new ClientManager();
>     Client client = manager.findClientByLogin(login);
>     if (client!=null && client.getPassword().equals(password)) {
>             request.getSession().setAttribute(CLIENT_KEY, client);
>     }
>     response.sendRedirect("/private/index.jsp");
> =============
> in /deploy/resources.war/private/index.jsp I have:
> ================
> <%
>     Enumeration e = request.getSession().getAttributeNames();
>     System.out.println("element names:");
>     while (e.hasMoreElements()) {
>         System.out.println("e.nextElement() = " + e.nextElement());
>     }
> %>
> ================
> And I recieve no elements in session. 
> Variables, sent in the request attributes, are accessible fine.
