User-defined input nodes
A user-defined input node is an extension to the broker that provides a new input node in addition to the nodes supplied with the product.
You create user-defined input nodes by using the C or Java™ programming language, or from a subflow, to provide message input to a message flow from a message queue when you want your broker to accept messages from a transport protocol other than WebSphere® MQ.
You can use a user-defined input node to receive data from an external data source and to allow that data to be processed in a broker. In this way, you can complement the primitive input node types provided by WebSphere Message Broker.
You cannot use a user-defined input node to provide the In terminal to a message subflow. If you want to provide the In terminal to a subflow, you must use the supplied Input node.
Before writing a user-defined node, make sure that you are familiar with the concepts that are introduced in Why use a user-defined extension? and User-defined extensions in the runtime environment.
