![]() It can be created from the connection factory object. JMSContext combines the functionality provided by the connection and session object. JMSContext is defined as part of the JMS 2.0 specification. ![]() When the session mode isn't specified, the Session.AUTO_ACKNOWLEDGE is picked by default. This value may be passed as the argument to the method createSession(int sessionMode) on the Connection object to specify that the session should use a local transaction. This acknowledgment mode instructs the session to lazily acknowledge the delivery of messages. The client acknowledges a consumed message by calling the message's acknowledge method. The session automatically acknowledges a client's receipt of a message either when the session has successfully returned from a call to receive or when the message listener the session has called to process the message successfully returns. Session modesĪ session can be created with any of the below modes. JMS API doesn't support receiving messages from service bus queues or topics with messaging sessions enabled. Session session = connection.createSession(false, Session.CLIENT_ACKNOWLEDGE) It can be utilized to create messages, message producers and consumers, but it also provides a transactional context to allow grouping of sends and receives into an atomic unit of work.Ī session can be created from the connection object as shown below. Connection connection = factory.createConnection() Ī session is a single-threaded context for producing and consuming messages. With Azure Service Bus, this represents a stateful connection between the application and Azure Service Bus over AMQP.Ī connection is created from the connection factory as shown below. ConnectionsĪ connection encapsulates a virtual connection with a JMS provider. ConnectionFactory factory = new ServiceBusJmsConnectionFactory(SERVICE_BUS_CONNECTION_STRING, null) Ī destination is the object a client uses to specify the target of the messages it produces and the source of the messages it consumes.ĭestinations map to entities in Azure Service Bus - queues (in point to point scenarios) and topics (in pub-sub scenarios). ![]() The connection string is a required parameter, but the other properties are optional. The factory can be created as shown here. Connection string - the connection string for the Azure Service Bus Premium tier namespace.The Connection factory can be instantiated with the below parameters. ![]() TokenCredential tokenCredential = new new ClientSecretCredentialBuilder() TokenCredential tokenCredential = new DefaultAzureCredentialBuilder()Ĭreate a service principal on Azure, and use this identity to create a TokenCredential. String host = "." ĬonnectionFactory factory = new ServiceBusJmsConnectionFactory(tokenCredential, host, null) Ĭreate a user assigned managed identity on Azure, and use this identity to create a TokenCredential. The token credential and host are required parameters, but the other properties are optional.
