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 each of them can be simulated using the WSO2 ESB.
 | How messaging can be used to invoke a procedure in another application. | ||
 | How messaging can be used to transfer data between applications. | ||
 | How messaging can be used to transmit events from one application to another. | ||
 | How an application that sends a message gets a response from the receiver. | ||
 | How a replier knows where to send the reply. | ||
 | How a requester that has received a reply knows which request the reply is for. | ||
 | How messaging can transmit an arbitrarily large amount of data. | ||
 | 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. |
