System.getProperty problems after EJB call

[tuisku]

Linux RedHat 7.1
Sun JDK 1.3.1
JBoss 2.4.3 + Tomcat 3.2.3
or
JBoss 2.4.1 + Jetty-3.1.RC9-1

---

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...

Reason ?

Wild guess is that you can't share the code with
JAAS standalone stuff (AppCallbackHandler
and LoginContext etc.) and omit the Servlet
login configuration in Web application, but
must stick with the JAAS-HOWTO example.
Servlet Container must know the user Principals
and Credentials.

Am I right?
