webMethods clients for JMS and C# are also Broker clients. For a JMS or C# client to exchange information with other clients, it needs to be assigned to a client group. For JMS or C# clients, the default client group configured by webMethods tools is named JMSClient (you can and should use your own application-specific client groups).

For JMS and C# clients, client group membership is necessary to assign permissions that specify whether clients can publish and subscribe to specific documents (topics and queues).

See Administering webMethods Broker for a detailed description of Broker client groups.
