Hi!
According to some postings in
http://www.mail-archive.com/rpc-user@xxxxxxxxxxxxxx/maillist.html
exactly the same question must have been posted in this list in sep 2002.
Sorry for this, but unfortunatly the kxmlrpc mailing-list archive is not
available.
Any idea, when the archive is going to work again?
Greetings,
Henrik
