org/extensions/xep-0030.html#info">3. Discovering Information About a Jabber Entity

A requesting entity may want to discover information about another entity on the network. The information desired generally is of two kinds:
1. The target entity's identity.
2. The features offered and protocols supported by the target entity.
@param jid The entity's JID. @return The service discovery result. @throws rocks.xmpp.core.stanza.model.StanzaException If the entity returned a stanza error. @throws rocks.xmpp.core.session.NoResponseException If the entity did not respond.
