Guys, Sorry that I missed this thread - I've been busy.
For the latest version of my distributable sessions (which is settling down now) you should check out Branch_3_2. If you want to use the CMP implementation (Greg) you will find it being built (jetty/output/lib/org.mortbay.j2ee.session-ejb.jar?), but no longer deployed - there are some class dependencies I need to clean up. That shouldn't stop you from using it. The default impl is now a fine-grained replication strategy using JavaGroups (you will need multicasting working and the 'all' config - just like JBoss clustering). This will be a lot faster than the CMP impl. This impl is still not production ready - since something deep inside JavaGroups (I think) hangs after stressing for a while - I am looking into it. If you want to run with 3.0.[12], simply take the jetty jars and the ejb-jar (mentioned above) and replace those in your 3.0.x tree with them. I'm sorry this stuff is taking so long to stabilise - it's a complicated area and has needed a lot of time - of which I am short at the moment. I'll be around to answer questions if you need me, Keep me posted, Jules Kim, Yong wrote: > Check my last message. > > Mitchell > > -----Original Message----- > From: Greg Turner [mailto:[EMAIL PROTECTED]] > Sent: Thursday, September 12, 2002 3:35 PM > To: [EMAIL PROTECTED] > Subject: Re: [JBoss-user] Http Session Clustering problem > > > Another approach to solving problem is to start with an empty class and see > if > that works > > public class MyJavaBean implements Serializable { > } > > If that does not work, then I would say thats a pretty good indication that > there is a problem with JBoss.
