[Design of Clustering on JBoss] - Re: JBCLUSTER-206 - Extract HB/JBC integration layer from EJ

by bstansberry＠jboss.com

Prabhat, I can release this today as a CR1. Could even call it a GA if necessary, although I'd prefer to wait in do that in another 1.5 weeks after I come back from vacation next week. I'd like to blog about it and have no time this week. One thing I'd like to change before cutting the release would be the name of the provider classes: from "org.jboss.hibernate.jbc.cacheprovider.(Optimistic)TreeCacheProvider" to "org.jboss.hibernate.jbc.cacheprovider.(Optimistic)JmxBoundTreeCacheProvider". Will that mess you guys up too much? Reason for this is to conform to the naming pattern of the providers shipped (in a different package) in Hibernate: TreeCacheProvider (which instantiates a JBC instance itself) JndiBoundTreeCacheProvider (which looks for a JBC instance in JNDI) JmxBoundTreeCacheProvider would then mean one that looks for a JBC instance in JMX. I could then easily enough create a TreeCacheProvider and a JndiBoundTreeCacheProvider that work like the standard hibernate equivalents.

[Design of EJB 3.0] - Re: Classloading problem in proxy factories

by bstansberry＠jboss.com

Ping Ron Sigal. That sounds vaguely familiar; i.e. something that got fixed [1]. This test is the same as what's in Branch_4_2, and it passes there, so remoting must be cleaning up there. Perhaps something got dropped between remoting versions. This kind of thing is the big weakness in the classloader leak tests -- temporary leaks until some short-term-cached resource gets cleaned up. But, so far we haven't hit any of those kind of things that couldn't be fixed, and the tests have caught about 7-10 classloader leaks already, so... [1] My vague memory goes to some last minute remoting SP fix before a 4.x release.....

[Design of Messaging on JBoss (Messaging/JBoss)] - Re: JGroups Protocol Stack Configuration & Shunning Behavior

by jhowell＠redhat.com

The only two places I see it are in /jms/src/main/org/jboss/jms/serverless/GroupConnection.java Which just logs public void channelShunned() { log.debug("channelShunned()"); } and /jms/src/main/org/jboss/jms/client/p2p/P2PConnectionDelegate.java public void channelShunned() { if (this.exceptionListener != null) { this.exceptionListener.onException(new JMSException("We were shunned.")); } } which I don't think are used in the clustering of the server anyway. Maybe Tim can confirm this. But I don't find a listener that implements channelShunned in the jbm server.

"bela(a)jboss.com" wrote : I was under the impression that JBM actually *does* rejoin the channel, but instead of letting JGroups do this automatically, they do it manually (by listening for a channelShunned() callback). Looking at org.jboss.messaging.core.impl.postoffice.GroupMember (where MembershipListener is implemented), I don't see anything using a ChannelListener (where channelShunned is specified), but I'm not sure that's a definitive answer regarding this.
