Hello.
I am trying to deploy this app that is composed of servlet+jsp+ejb in a
MVC framework.
This is working in "standart" (not clustered) jboss.
I changed the web descriptor to include httpsession clustering. (no ejb
clustering, to try to isolate the problems)
I end up with a "internal server error" when trying to access the app
homepage. There are some strange lines in the log file that I think may
give a clue. Here goes the log:

These are the strange lines that I've seen:
----
01:41:10,610 WARN [Manager] No Store. Falling back to a local session
implementation - NO HTTPSESSION DISTRIBUTION
----
01:42:07,352 ERROR [SubscribingInterceptor] could not get
AbstractReplicatedStore
----
The only line in this exception that refers to our code is
JwmaController.service. I'll post that code also:
public void service(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
Log1.trace("JwmaController service(request, response) begin");
//1. Handle session
HttpSession websession=req.getSession(true);
//Object o=websession.getValue("jwma.session"); $ deprecated
Object o=websession.getAttribute("jwma.session");
String acton=req.getParameter("acton");
String dome=req.getParameter("todo");
Log1.trace("JwmaController service() - acton = "+acton+" | todo =
"+dome, 1);
This second log doesn't ever happen, so it must be on one of the 4 lines
above. My guess is that it is in "getSession".
[UPDATE: It's not a guess anymore. I've added some more debug messages and
it really fails there.]
Any clue?
