Java CAPS - Exposing MTOM-capable Java CAPS Classic Web Service

If we overlook the fact that using web services to transfer large payloads is a very stupid idea, we will be faced with the need to implement the optimisation mechanisms to make transfer of large payloads using web services a little less inefficient from the stand point of the size of the over-the-wire data to be transferred.

The standardised, supported mechanism for this is the Message Transmission Optimisation Method (MTOM), http://en.wikipedia.org/wiki/MTOM. Java CAPS Repository-based Web Services don’t offer a convenient mechanism to provide MTOM support.

This note walks through the implementation of a Java CAPS Repository-based, eInsight-based web service and the implementation of the EJB-based Web Service Wrapper for this service, which provides support for MTOM. The Note discusses how to exercise the services using the NetBeans web services testing facilities and how to observe on-the-wire message exchanges.
