Class IQvCardHandler

  • All Implemented Interfaces:
    ChannelHandler, Module

    public class IQvCardHandler
    extends IQHandler
    Implements the TYPE_IQ vcard-temp protocol. Clients use this protocol to set and retrieve the vCard information associated with someone's account.

    A 'get' query retrieves the vcard for the addressee. A 'set' query sets the vcard information for the sender's account.

    Currently an empty implementation to allow usage with normal clients. Future implementation needed.

    Assumptions

    This handler assumes that the request is addressed to the server. An appropriate TYPE_IQ tag matcher should be placed in front of this one to route TYPE_IQ requests not addressed to the server to another channel (probably for direct delivery to the recipient).

    Warning

    There should be a way of determining whether a session has authorization to access this feature. I'm not sure it is a good idea to do authorization in each handler. It would be nice if the framework could assert authorization policies across channels.

    Warning

    I have noticed incompatibility between vCard XML used by Exodus and Psi. There is a new vCard standard going through the JSF JEP process. We might want to start either standardizing on clients (probably the most practical), sending notices for non-conformance (useful), or attempting to translate between client versions (not likely).
