copied!<p>I'd be curious to know more about your requirements. As another answer suggests, Terracotta may be exactly what you are looking for.</p> <p>There is a subtle difference however between what Terracotta provides, and what you are asking for, thus my inquiry.</p> <p>The difference is that as far as you are concerned, Terracotta does not provide "remote" references to objects - in fact the whole "remote" notion of RMI, JMS, etc. is entirely absent when using Terracotta.</p> <p>Rather, in Terracotta, all objects reside in large virtual heap. Threads, whether on Node 1, or Node 2, Node 3, Node 4, etc all have access to any object in the virtual heap.</p> <p>There's no special programming to learn, or special APIs, objects in the "virtual" heap have exactly the same behavior as objects in the local heap. </p> <p>In short, what Terracotta provides is a programming model for multiple JVMs that operates exactly the same as a the programming model for a single JVM. Threads in separate nodes simply behave like threads in a single node - object mutations, synchronized, wait, notify all behave exactly the same across nodes as as across threads - there's no difference.</p> <p>Furthermore, unlike any solution to come before it, object references are maintained across nodes - meaning you can use ==. It's all a part of maintaining the Java Memory Model across the cluster which is the fundamental requirement to make "regular" Java (e.g. POJOs, synchronized, wait/notify) work (none of that works if you don't / can't preserve object identity across the cluster).</p> <p>So the question comes back to you to further refine your requiements - for what purpose do you need "remote" pointers?</p>
