This chapter describes the messaging service feature for EAServer version 4.1, which supports the Java Messaging Service (JMS) 1.0.2 specification. You can use the message service to send messages to specific destinations and publish messages to be delivered to interested consumers. You can receive scheduled messages and message topic notifications, as well as asynchronously receive messages using message listeners.
To develop messaging service applications, you can use either the JMS API or the EAServer CORBA API. To ensure that your code is portable, Sybase recommends that you use the JMS API when performing nonadministrative tasks from Java clients and components. Use the EAServer CORBA API for your clients and components:
For programming languages other than Java
To automate administrative tasks
To assign a single message listener to multiple message queues
For information on configuring and administering the message service, see Chapter 8, “Setting up the Message Service,” in the EAServer System Administration Guide.
