Yea, i know and try to use it. The problem was with my application.
I have included html-tmpl-java into java servlets and have any
rmi-components,
that generates my hashtable for the templates. So i must run about all
entries and add the sessionID. But this is not the problem if i can get
the next version of html-template with the cool new feature ;-)

If you interested for the integration from html-template into
java-servlets
i can give you a short example.
