Class 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.

      • ServerStanzaHandler

        public ServerStanzaHandler​(PacketRouter router,

      • createSession

        protected void createSession​(org.xmlpull.v1.XmlPullParser xpp)
                      throws org.xmlpull.v1.XmlPullParserException,
                             IOException
        Description copied from class: StanzaHandler
        Uses the XPP to grab the opening stream tag and create an active session object. The session to create will depend on the sent namespace. In all cases, the method obtains the opening stream tag, checks for errors, and either creates a session or returns an error and kills the connection. If the connection remains open, the XPP will be set to be ready for the first packet. A call to next() should result in an START_TAG state with the first packet in the stream.
        Overrides:
        createSession in class StanzaHandler
        Parameters:
        xpp - the pull parser
        Throws:
        org.xmlpull.v1.XmlPullParserException - if an exception occurs reading from the pull parser
        IOException - if an IO exception occurs reading from the pull parser

      • tlsNegotiated

        protected void tlsNegotiated​(org.xmlpull.v1.XmlPullParser xpp)
                      throws org.xmlpull.v1.XmlPullParserException,
                             IOException
        Description copied from class: StanzaHandler
        TLS negotiation was successful so open a new stream and offer the new stream features. The new stream features will include available SASL mechanisms and specific features depending on the session type such as auth for Non-SASL authentication and register for in-band registration.
        Overrides:
        tlsNegotiated in class StanzaHandler
        Throws:
        org.xmlpull.v1.XmlPullParserException
        IOException

      • processIQ

        protected void processIQ​(org.xmpp.packet.IQ packet)
                  throws UnauthorizedException
        Description copied from class: StanzaHandler
        Process the received IQ packet. Registered PacketInterceptor will be invoked before and after the packet was routed.

        Subclasses may redefine this method for different reasons such as modifying the sender of the packet to avoid spoofing, rejecting the packet or even process the packet in another thread.

        Overrides:
        processIQ in class StanzaHandler
        Parameters:
        packet - the received packet.
        Throws:
        UnauthorizedException - if service is not available to sender.

      • processPresence

        protected void processPresence​(org.xmpp.packet.Presence packet)
                        throws UnauthorizedException
        Description copied from class: StanzaHandler
        Process the received Presence packet. Registered PacketInterceptor will be invoked before and after the packet was routed.

        Subclasses may redefine this method for different reasons such as modifying the sender of the packet to avoid spoofing, rejecting the packet or even process the packet in another thread.

        Overrides:
        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
        Description copied from class: StanzaHandler
        Process the received Message packet. Registered PacketInterceptor will be invoked before and after the packet was routed.

        Subclasses may redefine this method for different reasons such as modifying the sender of the packet to avoid spoofing, rejecting the packet or even process the packet in another thread.

        Overrides:
        processMessage in class StanzaHandler
        Parameters:
        packet - the received packet.
        Throws:
        UnauthorizedException - if service is not available to sender.
