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 WebSphere Message Broker does
not provide direct support for service publication, any of the mechanisms
described can be used with WebSphere Message Broker.
- Direct publishing
- The service provider sends the service description directly to the service
requester. You can accomplish this by using an e-mail attachment, an FTP site,
or a CD ROM distribution.
- Advertisement and Discovery of Services (ADS)
- A Web server becomes a read-only directory advertising its own services,
enabling B2B search engines to discover the services the Web server makes
available.
- DISCO
- The service requester uses a HTTP GET mechanism to retrieve a Web service
description from a network location that is specified by the service provider,
and is 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
specifications that allow businesses to register information about the Web
services they offer in order that other businesses can find them.
