When you design and configure message flows that support aggregation, there are some restrictions on the protocols that can be used by participating client applications:

WebSphere Business Integration Message Broker provides the following protocols and input and output nodes to support the request/reply model:

The following transport protocols do not support a request/reply model:

If you choose to create user-defined nodes, and use an alternative transport protocol, the protocol you use must meet the following criteria for input and output nodes to support aggregation requests and responses:

The protocol-specific output node must:

The protocol-specific input node must:

When you write user-defined nodes, you can override these properties by navigating to the Properties folder and using cniCreateElementAsFirstChild() or equivalent. Ensure that the value used for the Protocol is consistent and is unique for the protocol.
