Session handling with wml

[MAVOSS]

I'm trying to get struts working with wml. Everything works fine beside the
fact, that struts always thinks it is able to place a cookie at the browser
(Nokia 6210). This seems not to be working, as nothing keeps stored in
session. I can't reproduce this error with the blueprint from Nokia
Toolkit, even if cookies are deactivated. Manual URL-encoding has no
effect, as the session-id is never added to url if a cookie was set...
Anybody solved similar problem?
Thanx,    Maik.
