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.

    TODO Finish migration of s2s to use NIO instead of blocking threads. Migrate from ServerSocketReader.
