Ray, I changed the subject to pull out of the other thread.
The most elusive thing I found about getting ERJGroupsSynchronizer working is this: -Djava.net.preferIPv4Stack=true If you don’t set this switch on your JVM, the processes don’t hear each other. Also, you need to be on a network where UDP multicast works. If you’re deployed on AWS, I highly recommend this project: https://github.com/meltmedia/jgroups-aws It replaces the TCP discovery with a discovery mechanism that uses AWS tags. It works!

I want to add to the available documentation on this. Did anyone else notice that none of the examples use any of this? I tried to use it and could not get it to work. A bit frustrating. But it seems to be one of those technologies where in order to make it work, you need to set 7 variables and if you set 5, there is no response. If you set 2, no response. If you set the wrong 7, no response. So, I could not tell if I was very close to making it work, or completely misunderstanding it, since both behave the same. I _was_ able to do what I needed with ERJGroupsNotificationCenter. Because you can, it turns out, use remote notifications to implement an object synchronization scheme. Kind of lame, though. thanx - ray > > On Oct 14, 2013, at 11:43 AM, Christoph Wick <[email protected]> wrote: > >> Hi there, >> >> is there a webobjects way to send a message to other instances of my app on >> a server running WO monitor? >> >> I have developed a GUI to manage some app preferences.
