Hi Adrian, thanks very much for your answers. I have a few little questions about the clustering answers that perhaps you can give me advice on.

When it is notified I want the MBean to change the state of an Entity bean. This is fine on a single jboss version, but what I'd like some advice on, is how clustering will affect this. If I cluster and have one MBean for every box that does the same thing, will the Entity beans state get changed several times? Will each MBean get notified by a separate timer service each of which may become out of sync? what would your advice be? thanks very much again, Brian ----- Original Message ----- From: "Adrian Brock" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, February 19, 2003 6:16 PM Subject: Re: [JBoss-user] Basic JMX question > Hi Brian, > > Answers in line. > > >From: "Brian McSweeney" <[EMAIL PROTECTED]> > >Reply-To: [EMAIL PROTECTED] > >To: <[EMAIL PROTECTED]> > >Subject: [JBoss-user] Basic JMX question > >Date: Wed, 19 Feb 2003 16:03:24 -0000 > > > >Hi all, > >yet again in my quest to write container independent code, I'm stuck. :-) > > > >I want to use the Timer service in a container independent manner.
