Hi all!
My conf:
MyEclipse 4.0 final
tomcat 5.0.29I would like to pass a session variable (user credentials) from application homebase to application test. Both applications were deployed on the same tomcat-server and crosscontext=true for both Applications.
For example I was setting up a session variable in my request:
request.setAttribute("test", "Hello!!!!!");Next I’m trying to get the context of app2, and forward this request into this context. I “partitioned” the programcode to debug it, but it is still working without exception.
ActionServlet actionServlet = this.getServlet(); if (actionServlet == null) { System.out.println("actionServlet nuull"); } ServletConfig servletConfig = actionServlet.getServletConfig(); if (servletConfig == null) { System.out.println("servletConfig nuull"); } ServletContext servletContext = servletConfig.getServletContext(); if (servletContext == null) { System.out.println("servletContext nuull"); } ServletContext servletContextTest = servletContext.getContext("/test"); if (servletContextTest == null) { System.out.println("servletContextTest Null!"); } RequestDispatcher reqDis = servletContextTest.getRequestDispatcher("/testSessVar.do"); if (reqDis == null) { System.out.println("reqDis Null!"); } try { reqDis.include(request, response); } catch (ServletException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } catch(Exception e) { System.out.println(e); }The called Servlet testSessVar.do is calling a jsp-page called success.jsp.

My problem is, that the URL in my browser is still showing http://localhost:8080/HomeBase/LOGIN/userLogin.do – so my active Webapplication seems to be the application “Homebase”, not the application “test”.
However, it is not possible to map a struts-action with the submit-button of the success.jsp.
(Of course the struts-action-mapping is possible after calling the success.jsp withing the “test”-content […8080:/test/success.jsp])How is it possible to change/forward/link to another webapplication without loosing the session variables?
(When I’m forwarding with struts [context relativ, redirect….], the URL is localhost:8080/test….., but the session variables are gone).
thx for any help
greetings
MartinMartin,
This is an excellent question but I think you should ask it on the Struts mailing list in addition to here to make sure you get a reply, I honestly don’t have any suggestion fo ryou (not done cross context before).
