Message Construction¶
Message construction involves the architectural patterns of various constructs, functions, and activities involved in creating and transforming a message between applications.
This chapter introduces message construction patterns and how they can be simulated using the WSO2 Micro Integrator.
Command Message | ![]() |
How messaging can be used to invoke a procedure in another application. |
Document Message | ![]() |
How messaging can be used to transfer data between applications. |
Event Message | ![]() |
How messaging can be used to transmit events from one application to another. |
Request-Reply | ![]() |
How an application that sends a message gets a response from the receiver. |
Return Address | ![]() |
How a replier knows where to send the reply. |
Correlation Identifier | ![]() |
How a requester that has received a reply knows which request the reply is for. |
Message Sequence | ![]() |
How messaging can transmit an arbitrarily large amount of data. |
Message Expiration | ![]() |
How a sender indicates when a message should be considered stale and therefore should not be processed. |
Format Indicator | How a message’s data format can be designed to allow for possible future changes. |
