Thank you for your answer. Aclually I have no problem to connect to the server and use DistributedReplicantManager. I have only jbossall-client.jar and it's enough. the question is : Is it a correct way to get cluster(partition) names , and may be someone already faced with this problem and can give a good reference or code example how to discover jboss topology (clusters , servers).
