Usage
Using
jgroups component on the consumer side of the route will capture messages received by the JChannel associated with the endpoint and forward them to the Camel route. JGroups consumer processes incoming messages asynchronously.
// Capture messages from cluster named
// 'clusterName' and send them to Camel route.
from("jgroups:clusterName").to("seda:queue");
Using
jgroups component on the producer side of the route will forward body of the Camel exchanges to the JChannel instance managed by the endpoint.
// Send message to the cluster named 'clusterName'
from("direct:start").to("jgroups:clusterName");
