How do I develop publish/subscribe applications?
New users: use the links in this topic to get concept and reference information that is useful when you develop publish/subscribe applications.
Publish/subscribe is a style of messaging application in which
the providers of information (publishers) are decoupled from the consumers
of that information (subscribers) using a broker. The following samples
are examples of simple publish/subscribe message flows, and include
associated user applications. You can view information about samples only when
you use the information center that is integrated with the WebSphere® Message Broker Toolkit or the online information
center. You can run samples only when you use the information center
that is integrated with the WebSphere Message Broker Toolkit.
A publish/subscribe application can consist of a network of brokers
connected together. By connecting brokers together, publications can
be received by a client on any broker in the network.
- Where can I find an overview of publish/subscribe? For an overview of publish/subscribe, see the following topics:
- How do I use a publication node? Use the Publication node in your message flows to filter output messages and transmit them to subscribers who have registered an interest in a particular set of topics.
- What are command messages? Different types of command messages can be sent from an application to instruct the broker to perform the required task; for example to publish a message, or register a subscriber.
