Chapter 7: New Features in EAServer 4.0

Message service enhancements

EAServer 4.0 provides an implementation of the Java Message Service (JMS) API, message-driven bean support, and easier management of the message service.


Java Message Service API support

EAServer 4.0 provides implementations of the JMS API drivers, layered on top of the existing message service API. The JMS specification defines two messaging models: point-to-point for sending messages to specific message consumers, and Publish/Subscribe for publishing messages that are available to all consumers. For more information, see Chapter 31, “Using the Message Service,” in the EAServer Programmer’s Guide.


Message-driven bean support

Message driven bean (MDB) components integrate the EJB 2.0 and Java Message Service architectures. See “Message-driven beans” for more information.


EAServer Manager enhancements

You can now use EAServer Manager to add and configure the message service components that allow you to send and receive messages. For more information, see Chapter 8, “Setting up the Message Service,” in the EAServer System Administration Guide.
