Question

is there anyway of sharing the Session data across two different JSP (i mean two dynamic web project)
projects

in the 1st project i test like that

  <%if(session.getAttribute("UserName") != null ){%>
  .
  .
   do something
     .
    <% } %>

it’s ok

but when i do that in the 2nd project i got this exception

Etat HTTP 404 - /myEbookSearchClient/myEBook/WebContent/JSP/session/index.jsp

  --------------------------------------------------------------------------------

   type Rapport d''état

    message /myEbookSearchClient/myEBook/WebContent/JSP/session/index.jsp

   description La ressource demandée (/myEbookSearchClient/myEBook/WebContent/JSP/session/index.jsp)        n'est pas disponible.


   --------------------------------------------------------------------------------

  Apache Tomcat/7.0.5

Basically, I’m jumping from a page in one to a page in another

any idea how to Shar the session of the 1st project with the 2 project ?

Answer 1

You cant. Attempting to share sessions is discouraged for a variety of reasons primarily related to security.

Servlet contexxt methods that retreieve a session by id or return an enumeration of all now all do nothing for precisely this reason.

You will need to share data in some other manner such as a cache or via a database.
