Hello Marcin, XmlStream is an implementation of XMPP/Jabber protocol (which is widely used for Instant Messaging). If you have time please read about this on www.xmpp.org. The reason why /frame handler was not executed is because XMPP/Jabber sessions starts and ends with streams like for example:
<*stream*:*stream* xmlns:*stream*="http://etherx.jabber.org/streams";> . . . <message to='[email protected]' from='[email protected]> <body>Hello World!</body> </message> . . . </stream:stream> You might want to take a look at twisted XML-RPC libraries. --- Alvin On Wed, Dec 17, 2008 at 7:25 PM, Marcin Gliński <[email protected]> wrote: > Hello! > > There's a problem I can't find an answer to.
