So you will have one instance of your singleton for each node in your cluster. - Peter - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Session Objects
Yes it will, this won't work accross a cluster. You need to use the regular session manager. Is there any reason why you put the sessions in a singleton?

Could you explain why this won't work across a cluster? Thanks.

RE: Session Objects
It's not impossible to make this work over a cluster but not with the included clustering classes in tomcat. You would have to write your own clustering classes. The reason why it won't work is that each singleton will be individual to a classloader and each tomcat accross the cluster will obviously have its own classloaders. The standard clustering only shares the sessions that are stored within the standard session manager in tomcat. -Original Message- From: Shey Rab Pawo [mailto:[EMAIL PROTECTED] Sent: 08 February 2005 17:44 To: Tomcat Users List Subject: Re: Session Objects Could you explain why this won't work across a cluster?
