Clustering solution for Java
Applications:

For a web and/or Enterprise 
Application, deployable on an
application server, be it
IBM Websphere, BEA Weblogic, 
Redhat JBoss etc., cluster 
enabled nodes can be configured
to deploy components 
(transactional, shareable) within
clustered node, distributed across
many clustered JVM. In order to 
achive High Availability and 
Failover, one has to evaluate 
Options and applications server 
features.



For non web and/or Enterprise applications, like a pure Java application,
running on command prompt How can we achive HA (High availability), 
and fail over or achive desired performance, so as to have clustering 
for pure Java application?

There is a very flexible and dynamic clustering Framework, can be found at
https://shoal.dev.java.net
It can make available communication among nodes with api, and this makes 
Java application broadcast messages in form of objects to many participating
nodes in clustered environment.

To my understanding or approach of evaluating any Technology/Framework is to
understand features of the Technology/ Framework and co-relating with the
task/requirement at hand, once all the tasks/ requirement are functionality
supported by the Technology/ Framework  on hand, then comes prototyping
probable uses of these features and then try to bench mark feature 
implemented in form of prototype to performance, and availability and most
of the NFR (Non Functional Requirement).

Message/Communication across different ndes in a group of cluster is an 
essential part of clustered environment. JavaGroup is an open source 
framework from sourceforge.org that says "Reliable group
communication based an IP multicast and configurable protocol stack" 
at http://www.sourceforge.net/projects/javagroups/.

JPPF (Java Parallel Processing Framework) from sourceforge that gives Java
application a platform for running application in parallel and achive better
performance.

JPPF can be found at http://www.sourceforge.net/projects/jppf-project.
