Send and receive SOAP messages with large attachments in IBM Integration Bus
This tutorial explains how to send and receive SOAP messages with large attachments in IBM Integration Bus by using the HTTPRequest node. It describes the built-in size limits of the various data types in IBM Integration Bus. It also highlights several approaches to maximize the size of data that can be successfully processed and shows an example of these techniques. In the example, a message flow sends and receives SOAP requests that have large attachments by using the Message Transmission Optimization Mechanism (MTOM) and the Multipurpose Internet Mail Extensions (MIME) parser. You can reuse the code snippets that are provided in your own integration projects.
