Hi, What are your needs? Why distributed singleton or distributed locking are so important ? Perhaps you can use Database to implement locking functionality and Jgroups library to replicate state (or distributed singleton) across members of a group (see www.jgroups.org).

Our web application uses locking and Singleton pattern. I am making researches - is there a possibility to move to cluster architecture or load balancing. Distributed locking is not possible. Distiributed Singleton (static variables) seems not to be possible too. So web applications, that use locking or Singleton cannot use cluster architecture or load balancing. Maybe there is indirect way of implementing distributed locking or distributed Singleton? For example, code that needs synchronization may be concentrated in "main" Tomcat, and other Tomcats will call this code via http or SOAP? Is there any way to move web application with locking and Singleton to cluster or load balancing?
