Hi All, I'm try to perform some tests with ClusteredConnectionFactory. When I use RoundRobinLoadBalancingFactory, the test work fine. So, when I try to use NoLoadBalancingLoadBalancingFactory, an INFO appear when jboss is starting. The INFO is : | org.jboss.deployment.DeploymentException: Exception setting attribute javax.management.Attribute@13244cd on mbean jboss.messaging.connectionfactory:service=ClusteredConnectionFactory; - nested throwable: (java.lang.InstantiationException: org.jboss.jms.client.plugin.NoLoadBalancingLoadBalancingFactory). The configuration is like this : | <attribute name="SupportsLoadBalancing">true</attribute> | <attribute name="LoadBalancingFactory">org.jboss.jms.client.plugin.NoLoadBalancingLoadBalancingFactory</attribute> | Thanks Rogério Rondini View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4095384#...
