Sun Java Message Service classes and interfaces

The following tables list the JMS objects contained in the package javax.jms. Interfaces marked with * are implemented by applications. Interfaces marked with ** are implemented by appservers.

Interface Description

BytesMessage Used to send a message containing a stream of uninterpreted bytes.

Connection A client's active connection to its JMS provider.

ConnectionConsumer For appservers, a special facility for creating a ConnectionConsumer.

ConnectionFactory A set of connection configuration parameters that an administrator has defined.

ConnectionMetaData Information that describes the Connection.

DeliveryMode Delivery modes supported by JMS.

Destination Parent interface for Queue and Topic.

ExceptionListener* Used to receive exceptions thrown by Connections asynchronous delivery threads.

MapMessage Used to send a set of name-value pairs where names are Strings and values are Java primitive types.

Message Root interface of all JMS messages.

MessageConsumer Parent interface for all message consumers.

MessageListener* Used to receive asynchronously delivered messages.

MessageProducer Used by a client to send messages to a destination.

ObjectMessage Used to send a message that contains a serializable Java object.

Queue A provider-specific queue name.

QueueBrowser Used by a client to look at messages on a queue without removing them.

QueueConnection An active connection to a JMS point-to-point provider.

QueueConnectionFactory Used by a client to create QueueConnections with a JMS point-to-point provider.

QueueReceiver Used by a client to receive messages that have been delivered to a queue.

QueueSender Used by a client to send messages to a queue.

QueueSession Provides methods to create QueueReceivers, QueueSenders, QueueBrowsers and TemporaryQueues.

ServerSession ** An object implemented by an appserver.

ServerSessionPool ** An object implemented by an appserver to provide a pool of ServerSessions for processing the messages of a ConnectionConsumer.

Session A single-threaded context for producing and consuming messages.

StreamMessage Used to send a stream of Java primitives.

TemporaryQueue A unique queue object created for the duration of a QueueConnection.

TemporaryTopic A unique Topic object created for the duration of a TopicConnection.

TextMessage Used to send a message containing a java.lang.String.

Topic A provider-specific topic name.

TopicConnection An active connection to a JMS Publish/Subscribe provider.

TopicConnectionFactory Used by a client to create TopicConnections with a JMS Publish/Subscribe provider.

TopicPublisher Used by a client to publish messages on a topic.

TopicSession Provides methods to create TopicPublishers, TopicSubscribers and TemporaryTopics.

TopicSubscriber Used by a client to receive messages that have been published to a topic.

XAConnection Extends the capability of Connection by providing an XASession.

XAConnectionFactory Used by some appservers to provide support for grouping Java Transaction Service (JTS)-capable resource use into a distributed transaction.

XAQueueConnection Provides the same create options as QueueConnection.

XAQueueConnectionFactory Provides the same create options as a QueueConnectionFactory.

XAQueueSession Provides a regular QueueSession that can be used to create QueueReceivers, QueueSenders and QueueBrowsers.

XASession Extends the capability of Session by adding access to a JMS provider's support for the Java Transaction API (JTA).

XATopicConnection Provides the same create options as TopicConnection.

XATopicConnectionFactory Provides the same create options as TopicConnectionFactory.

XATopicSession Provides a regular TopicSession which can be used to create TopicSubscribers and TopicPublishers.
