Method Detail

connect

public void connect()
             throws IOException

Connects to the specified XMPP server using a socket connection. Stream features are negotiated until SASL negotiation, which will be negotiated separately in the XmppSession.login(String, String) method.

If only a XMPP service domain has been specified, it is tried to resolve the FQDN via SRV lookup.
If that fails, it is tried to connect directly the XMPP service domain on port 5222.
If a hostname and port have been specified, these are used to establish the connection.
If a proxy has been specified, the connection is established through this proxy.
