jsp - servlet Session-authentication problem

[P.Goovaerts@xxxxxxxxxx]

A webapp has an index.html, 2 servlets(A)(B), 3 JSP's(A)(B)(error) and 1
databean. The application has 'Basic Authentication' activated in WebServer
(WAS3.5.6)

When index.html is launched, userid-password is asked by the server. After
receiving correct info, index.html is displayed and it automatically
launches Servlet(A).

This Servlet(A), creates a new session, get's data from the AS400 and
stores the data into the session. Finally it launches JSP(A) using
requestdispatcher:
'getServletConfig().getServletContext
().getRequestDispatcher(httppage).forward(req, res);'

JSP(A) is displayed and asks for a value to find data. When value is
entered, user submits the form which actually call's Servlet(B). In short,
this servlet does the following:
session = req.getSession(true);
id = session.getId();
if (session.isNew()) {
   httppage='error.jsp';
}
else{
   fillDataBean...;
   httppage='JSP2.jsp';
}
getServletConfig().getServletContext
().getRequestDispatcher(httppage).forward(req, res);

PROBLEM:
The first time Servlet(B) is executed (servlet loaded by server), I receive
JSP2.jsp which is correct. All subsequent calls end in error!
Even when I quit the browser, reload index.html and reconnect, the
error.jsp is shown which indicates that a new session is created.

The only clue I have is that 'session = req.getSession(true);' throws an
authorization-exception as follows:

com.ibm.websphere.servlet.session.UnauthorizedSessionRequestException:
SessionContext: a user authenticated as anonymous has attempted to access a
session owned by user:CLIPPER/S-1-5-21-346438834-254567744-1563503735-1100
