[Clustering/JBoss] - Re: Clustering / Multicast routing

by lludlow2

Brian, thanks for all of your help. I do have another question regarding on how we are setting up the 3 nodes. I am using apache with mod_jk and want to setup the cluster as follows. | Node1 Node2 Node3 | Active Standby Active | Buddy node2 Buddy node2 | and setup the load balancer to send traffic to either node1 or node3 and only send to node2 if 1 or 3 are down I want to do this to reduce the amount of memory required for running this many instances. >From my understanding the session state will only be replicated to node2 from either of the other active nodes unless node2 goes down. Will this work? and is it worth while to do it this way??

[Beginners Corner] - Re: A new understanding of ClassLoaders...

by PeterJ

Not quite. Things in the WAR can see everything, but nothing can see into the WAR. Other than that, everybody can see everybody else. Everything in the lib, deploy, ear, sar are in the same class repository (thus they all have visibility to each other) by default, though you can configure an ear or sar to use a separate class repository (see the JBoss Messaging sar for an example) in which case things in that ear and sar are hidden in much the same way things in a war are hidden. By the way, I created some simple classes that referenced each other and deployed them different locations to verify the above.

[JBoss Seam] - Latest CVS seam-gen..."The page isn't redirecting properly"

by sjmenden

Using latest code in CVS, when I generate a basic project with seam-gen and two enties, upon hitting http://localhost:8080/myapp for the first time I receive: "The page isn't redirecting properly" I tried this by generating another project with existing entities, same issue. My previous apps that I didn't seam-gen work fine.

[JBoss Seam] - Re: Conversation @Begin

by gavin.king＠jboss.com

@Begin is conditional upon the return value of the method. Use Conversation.instance()...... instead. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4020710#4020710 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4020710

[JBossCache] - Re: Optimistic DataVersioningException on read-only objects

by manik.surtani＠jboss.com

This is expected behaviour. If you have concurrent threads changing the same node at the same time, one of the threads will fail. In pessimistic locking, the 2 threads are NOT ALLOWED to change nodes at the same time and one thread waits. This leads to poor concurrency. Optimistic locking allows both threads to access nodes at the same time and hopes that one thread will just read and not write. If simultaneous writes happen, you will naturally get a concurrent modification exception.
