As Carl says the M2.1 Java code base has an active-passive setup for
the broker. For the client it has all be hidden away. All that a user
need do is to specify the two brokers in the connection url and the
client will automatically attempt to connect to the second broker if
the first goes down.

Details of the Connection URL can be found here :

The Java cluster module was for M1 and had serious problems as AMQP
0_8 which M1 supports has no support for clustering.

What are you trying to achieve with clustering perhaps the upcoming
work on Message Federation (QPID-946) for the Java broker will suit.

Martin
