[JDEV] Re: Urgent: Help on Jabber Server.

[chandan sonaye]

Daniel,

Thanks for your reply and info. Will certainly try this.

At the same time, we have a design need where the client specifies the
frequency and periodicity when it wants information from the respective
application servers e.g. check mail, news etc. server/s every x minutes. The
purpose is to reduce interruption to the user from immediate versus periodic
notification. That is why we thought Jabber would poll the relevant servers.

Secondly, we do not wish to send the full message content (e.g. mails, news,
documents etc.) but only notifications of their availability. Therefore at the
Jabber client end, a user would click on the links to the contents (which
would appear as pop-up's) and download them directly from the respective
servers (bypassing Jabber server and client) to open in the respective client
applications.

The second part of your answer did not describe how to set the time (duration)
of unavailability at the server (e.g. to temporarily suspend the operations
above because user is online but unavailable as in DND). Is it that the client
notifies and sets the setting on the server to online?

It will help us to understand the power and flexibility of Jabber (as well as
where we may extend its functionality because of the application and project
we are working on) if we had the following info:
        * Detailed documents about writing Transports and Etherx.
        * Details about the Module and Service API's (The links from
http://docs.jabber.org/general/architecture/
are broken.

Your help is appreciated ASAP. Thanks.

Sarang.
