Chapter 9. Sending Binary Data with SOAP MTOM
Abstract
SOAP Message Transmission Optimization Mechanism (MTOM) replaces SOAP with attachments as a mechanism for sending binary data as part of an XML message. Using MTOM with Apache CXF requires adding the correct schema types to a service's contract and enabling the MTOM optimizations.
9.1. Overview of MTOM
SOAP Message Transmission Optimization Mechanism (MTOM) specifies an optimized method for sending binary data as part of a SOAP message. Unlike SOAP with Attachments, MTOM requires the use of XML-binary Optimized Packaging (XOP) packages for transmitting binary data. Using MTOM to send binary data does not require you to fully define the MIME Multipart/Related message as part of the SOAP binding. It does, however, require that you do the following:
- Annotate the data that you are going to send as an attachment.You can annotate either your WSDL or the Java class that implements your data.
- Enable the runtime's MTOM support.This can be done either programmatically or through configuration.
- Develop a
DataHandlerfor the data being passed as an attachment.NoteDevelopingDataHandlers is beyond the scope of this book.
