Hi.
We are using Oracle9i Application Server (which is more or less the same
engine as in Oracle 8.1.7 JServer). We use OSE in the appserver to deploy
servlets and jsp into the database.
A Jsp-page let's the user log in, and sets some login information in the
HttpSession of the client. The client then goes to a servlet which tries to
use the information set to the users session. This does not work :/ Somehow
the session doesn't exist.
HttpSession sess = request.getSession(false); returns null in the servlet.
I suppose this is because the jsp and the servlet doesn't share the same
SessionContext?
If I try the same thing in Tomcat 3.2 it works - the jsp and servlet can use
the same context.
I've also tried the same classes on J2EE-RI 1.2.1, and this server behaves
just like Oracles server - the jsp and servlet do not have access to the
same session.
Any ideas? I'm attaching the source-files for a simple jsp and servlet that
was used to test the above.
/Best Regards, Anders.
