Hi devs,
I'm currently working on a network event distribution system.
The goal is to be able to shared events across XWiki instance (or not
XWiki) of a same network groups.
There is two target:
- unique easy clustering channel: if every XWiki instance of a network
group share the events it's becoming easy to make sure all instance of
the same cluster are synchronized and not only the code which is using
default cache system
- a new push communication interface to know what append on a farm for
network administrator or for softs like XWord and XEclipse to easily
update pages list etc...
To summarize I plan to do a Remote Observation Manager module which
send events coming for Observation Manager and inject in it events
coming for the network.
See http://dev.xwiki.org/xwiki/bin/view/Design/DistributedEvents for
more details (like events converters etc...).
For now my choice is on jgroups for the network part which is simple
to use, very configurable and well known. I looked at some other like
JMS or Hazelcast but after all, I think jgroups contains all i need
and is very light.
Would be great if some of you who has experience on this (or not)
could shoot with all remarks and suggestions.
I should be able to commit a first try based on jgroups this week on sandbox.
Thanks,

Hi Thomas
How you will be able to share it with Non-Xwiki instance?

For the purely technical part In JAVA you will just need to reuse APIs
you need and jgroups, you can directly reuse the component itself
(plus it's dependencies ObservationManager and ComponentManager) for
example. I seen there is a port of jgroups in .Net called GCT but i
seems dead did not looked much at it yet. Then for any client to
really receive events from an XWiki instance it mainly depends on the
configuration of jgroups which has membership management.
If it's important to support a large number of languages, I think JMS
is better since ActiveMQ (http://activemq.apache.org/) "supports a
variety of Cross Language Clients and Protocols from Java, C, C++, C#,
Ruby, Perl, Python, PHP ".
Note that we can write a jgroups based module now since it's the
easiest for inter-XWiki/JAVA for the first target which is clustering
and latter a JMS based one or any other since nobody is supposed to
directly call the module so you can change it easily without touching
anything else in XWiki, you can even imagine having several event
distribution modules at the same time (like one basic for inter-XWiki
and one readonly with larger clients languages support).

Hi Thomas
In my opinion jgroups is better choice. Please keep me in
the loop for this module. You can tell me what to do so that we can make
progress on
this module.

Sure.
You should watch http://jira.xwiki.org/jira/browse/XWIKI-3476, it's
the first place where i will add comments about what i do.

HI Thomas,
I'm exteremly new to XWiki and have been looking for a way to do a
particular element but I just need some slight clarification if its what
this tool will be for (or if I'm being dense and not realising how to do
it already with the documentation I've read).
We are looking to have several Wikis setup for each of our departments
internally at our company and we want them all to have a specific panel
of global links - this 'Global Panel' will solely have links into the
other assorted wikis and maybe a few other handy links for our own use.
What I want to know is: will this new tool allow us to make changes to
the first wiki we built's Global Panel and then push that change to all
the others?
Currently each wiki is seperate as such but all are linked to via our
main wiki and present in the wiki farm. I've been racking my brain over
this and if this tool will allow us to do this then that would be
awesome. Will this tool you are developing allow other resources to be
edited on one wiki and auto populate the same areas on other wikis too?
I'm highly curious as otherwise we may have to change our planned
infrastructure.
Thanks for the info thus far though and I will be watching this with
great interest :)
Regards,
Tim

If what you're trying to do only involves having the exact same panel
replicated in all your subwikis, it can already be done as of right now :-)
To do this, here's what you need to do:
- Let's assume that your main panel is on www.yourdomain.org and is
called Panels.MainPanel
- Go to your first subwiki's admin page in edit object mode
subwiki1.yourdomain.org/xwiki/bin/edit/XWiki/XWikiPreferences?editor=object
- Find the panels field (either left or right panels depending on your
preference)
- In the field, put the panel name in the following way:
xwiki:Panels.MainPanel
- Save the page
- Repeat with all your subwikis
Now, your subwiki uses a panel stored on your main wiki. Each time you
change the panel, its changes will be reflected on all subwikis. Basically,
you can reference and include pages from other wikis anywhere in your
subwikis using the following syntax : wikiname:SpaceName.PageName
Hope this helps,
Guillaume

No actually this tool gool is to share events between completely
different instance of XWiki (or any other tools implementing the right
api), if your use case is a wiki farm, all the wikis are "vistual"
which mean the whole farm is on the same XWiki instance and already
share events or anything else.
Now what you want to do sounds more like insert some main wiki panel
into sub wikis so you can do it easily whith what Guillaume explained.
Currently each wiki is seperate as such but all are linked to via our
main wiki and present in the wiki farm. I've been racking my brain over
this and if this tool will allow us to do this then that would be
