Class ServerStanzaHandler

org.jivesoftware.openfire.net.StanzaHandler

org.jivesoftware.openfire.net.ServerStanzaHandler

public class ServerStanzaHandler
extends StanzaHandler

Handler of XML stanzas sent by remote servers. Remote servers that send stanzas with no TO or FROM will get their connections closed. Moreover, remote servers that try to send stanzas from a not validated domain will also get their connections closed.

Server-to-server communication requires two TCP connections between the servers where one is used for sending packets whilst the other connection is used for receiving packets. The connection used for receiving packets will use a ServerStanzaHandler since the other connection will not receive packets.

Method Detail

getAdditionalNamespaces

protected String getAdditionalNamespaces()

Overrides:

getAdditionalNamespaces in class StanzaHandler

processIQ

protected void processIQ(org.xmpp.packet.IQ packet)
                  throws UnauthorizedException

Description copied from class: StanzaHandler

processPresence in class StanzaHandler

Parameters:

packet - the received packet.

Throws:

UnauthorizedException - if service is not available to sender.

processMessage

protected void processMessage(org.xmpp.packet.Message packet)
                       throws UnauthorizedException
