JAAS LoginModule - how do I get the "JSessionId"

Question

Hi,
is there any possibility to get the JSessionId from a custom JAAS LoginModule for the WebAS 6.40 Server.
My first attempt was to read the JSESSIONID-Cookie from the Http-Request via the HttpGetterCallback-Class.
((HttpGetterCallback) callbacks[1]).setType(HttpCallback.COOKIE);
((HttpGetterCallback) callbacks[1]).setName("JSESSIONID");
It worked well, till I noticed that sometimes the JSessionId-Cookie doesn't exist.
The reason is, that the JSession-Cookie was set after the http-request has passed my login-modul.
So, if I got a cookie-value, it sometimes was the JSessionID from an earlier session.
So, my question:
Is there any other posibility to get the JSessionId?
If there is a way to get the ServletRequest-instance,  I could reach the SessionId via "HttpServletRequest.getSession()".
Any idea? Any hints?

This is only available for NetWeaver Portal, not NetWeaver Application Server(WebAS). host and port can be obtained using the following code:
               Callback[] callbacks = new Callback[3];
               callbacks[0] = new NameCallback("UserId: ");
               callbacks[1] = new PasswordCallback("Password: ", false);
               // get host name and port
               HttpGetterCallback getterCallback = new HttpGetterCallback();
               getterCallback.setType(HttpCallback.HEADER);
               getterCallback.setName("Host");
               callbacks[2] = getterCallback;
               try {
                    callbackHandler.handle(callbacks);
               } catch (Exception ex) {
                    throw new LoginException(ex + "");
               Object retValue = ((HttpGetterCallback)callbacks[2]).getValue(); //get host
host and port will be returned in the following format SERVER.COMPANY.COM:50000
Currently WebAS is not able to return the resource as per SAP development.
