Class ConnectionConfiguration

java.lang.Object
org.jivesoftware.smack.ConnectionConfiguration
Direct Known Subclasses:
ModularXmppClientToServerConnectionConfiguration
public abstract class ConnectionConfiguration extends Object
The connection configuration used for XMPP client-to-server connections. A well configured XMPP service will typically only require you to provide two parameters: The XMPP address, also known as the JID, of the user and the password. All other configuration parameters could ideally be determined automatically by Smack. Hence, it is often enough to call ConnectionConfiguration.Builder.setXmppAddressAndPassword(CharSequence, String).

Technically there are typically at least two parameters required: Some kind of credentials for authentication. And the XMPP service domain. The credentials often consists of a username and password use for the SASL authentication. But there are also other authentication mechanisms, like client side certificates, which do not require a particular username and password.

There are some misconceptions about XMPP client-to-server parameters: The first is that the username used for authentication will be equal to the localpart of the bound XMPP address after authentication. While this is usually true, it is not required. Technically the username used for authentication and the resulting XMPP address are completely independent from each other. The second common misconception steers from the terms "XMPP host" and "XMPP service domain": An XMPP service host is a system which hosts one or multiple XMPP domains. The "XMPP service domain" will be usually the domainpart of the bound JID. This domain is used to verify the remote endpoint, typically using TLS. This third misconception is that the XMPP service domain is required to become the domainpart of the bound JID. Again, while this is very common to be true, it is not strictly required.

  • Field Details

    • xmppServiceDomain

      protected final org.jxmpp.jid.DomainBareJid xmppServiceDomain
      The XMPP domain of the XMPP Service. Usually servers use the same service name as the name of the server. However, there are some servers like google where host would be talk.google.com and the serviceName would be gmail.com.
