not implemented right now, how would you solve conflicts?
Filip -----Original Message----- From: Mike Duffy [mailto:[EMAIL PROTECTED] Sent: Friday, April 09, 2004 5:48 PM To: Tomcat Users List Subject: Clustering Application Scope Objects I've read documentation for The Tomcat 5 Servlet/JSP Container: Clustering/Session Replication HOW-TO http://jakarta.apache.org/tomcat/tomcat-5.0-doc/cluster-howto.html I understand clustering for individual user sessions. Are there any correlated methods for clustering application scope objects? The J2EE API for the Interface ServletContext states, "In the case of a web application marked "distributed" in its deployment descriptor, there will be one context instance for each virtual machine. In this situation, the context cannot be used as a location to share global information (because the information won't be truly global). Use an external resource like a database instead." Rather than use a database, what I would like to be able to do is make a call to servlet.getServletContext().setAttribute(key, object); and have the object stored in the application scope of all servers in the cluster. I know that EJBs were designed to serve this purpose; however, I would like to bypass the overhead and complexities of EJBs. If there isn't a switch that can be flipped in Tomcat, there might be a way to create a lightweight JMS administration class to serve this purpose. Has anyone tried this? If the answer to this question is RTFM, please send a link; I've looked through the documentation and I can't seem to find a clear reference. Thanks for your time and consideration.
