A service description can be published using a
number of different mechanisms; each mechanism has different capabilities,
and is suitable for use in different situations. When necessary, a service
description can be published in more than one way. Although CICS® does
not provide direct support for service publication, any of the mechanisms
described can be used with CICS.
- Direct publishing
- This is the simplest mechanism for publishing service descriptions: the
service provider sends the service description directly to the service requester.
Ways to accomplish this include using an e-mail attachment, an FTP site, or
a CD ROM distribution.
- Advertisement and Discovery of Services (ADS)
- DISCO
- These proprietary protocols provide a dynamic publication mechanism. The
service requester uses a simple HTTP GET mechanism to retrieve a Web service
descriptions from a network location that is specified by the service provider,
and identified with a URL.
- Universal Description, Discovery and Integration (UDDI)
- A specification for distributed Web-based information registries of Web
services. UDDI is also a publicly accessible set of implementations of the
specification that allow businesses to register information about the Web
services they offer so that other businesses can find them.
