Can somebody tell me what is wrong here:

Steps:
1) login.jsp --- FORM POST (uid,pwd) --->
2) PersonHandlingServlet --- EJB Call JAAS login() --->
3) login.jsp?action=process

I don't use Servlet Container's FORM-based login features, but do it manually at the moment.

Everything goes well until we do response.sendRedirect("/login.jsp") at step 2.
Servlet container can't show the login.jsp anymore.

The problems seem to originate from the fact that
whatever System.getProperty(...) returns null.
As I tested ...

at step 1)

>>> System.getProperty('java.io.tmpdir') = /tmp

at step 3)

>>> System.getProperty('java.io.tmpdir') = null

Why this?, in between we make EJB calls...

This is an Servlet application that works without
the EJB layer and the EJB layer works with a
Java standalone program just fine...
