Hello! Thank you for answers! I will try to use JGroups
We have data, that is often need to be read. And it is rarely written. It is implemented using Singleton pattern. Synchronization is used in several parts of web application. It is used mostly to access database Thank you, Igor ----- Original Message ----- From: "LERBSCHER Jean-Pierre" <[EMAIL PROTECTED]> To: "'Tomcat Users List'" <[EMAIL PROTECTED]> Sent: Thursday, September 30, 2004 10:41 AM Subject: RE : Synchronization in cluster Hi, What are your needs?
