Frequently asked questions about Echo 3

How do I access the http session object from the echo application

• You can use the http session object to access/store informations in the session object

• You should however not use this a a place to store application state informations, as of svn version 2208 (2009.09.27) it is now possible to have multiple windows per session ( http://echo.nextapp.com/site/node/4944)

• The correct place for per-application information is the http://echo.nextapp.com/content/echo3/doc/3.0/api/public/app/nextapp/echo/app/ApplicationInstance.html class.

Connection conn = WebContainerServlet.getActiveConnection();
if (conn != null)
{
    HttpSession thisSession = conn.getRequest().getSession(false);
    if (thisSession != null)
    {
        _user= (IUser) thisSession.getAttribute("myUser");
    }
}
