[ http://jira.jboss.com/jira/browse/JBAS-4303?page=comments#action_12358494 ]
Penkov Vladimir commented on JBAS-4303:
---------------------------------------
Workaround:
Create filter:
======================
import javax.servlet.*;
import javax.servlet.http.HttpServletRequest;
import java.io.IOException;
import java.util.Enumeration;
public class SessionBug implements Filter {
public void doFilter(ServletRequest req, ServletResponse resp, FilterChain chain)
throws ServletException, IOException {
HttpServletRequest request = (HttpServletRequest) req;
Enumeration e = request.getSession().getAttributeNames();
while (e.hasMoreElements()) {
String name = (String) e.nextElement();
request.setAttribute("sessionbug."+name,
request.getSession().getAttribute(name));
}
chain.doFilter(req, resp);
}
}
======================
add in web.xml:
======================
<filter>
<filter-name>SessionBugJBAS4303</filter-name>
<filter-class>imagewarehouse.web.filter.SessionBug</filter-class>
</filter>
<filter-mapping>
<filter-name>SessionBugJBAS4303</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>
======================
Now you can get session attribute from request in jsp:
======================
<%
request.setAttribute("client",
request.getAttribute("sessionbug."+Constants.CLIENT_KEY));
%>
======================
Web session is empty when forwarding request to another web context.

Key: JBAS-4303
URL: http://jira.jboss.com/jira/browse/JBAS-4303
Project: JBoss Application Server
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: Web (Tomcat) service
Affects Versions: JBossAS-4.0.4.GA
Environment: Fedora Core 6
Reporter: Penkov Vladimir
Assigned To: Remy Maucherat
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.
