UDDI

The Universal Description, Discovery and Integration (UDDI) specification defines a way to publish and discover information about web services. UDDI relies on a distributed registry of different businesses and the descriptions of their services implemented using a common XML format. This framework allows you to access public UDDI sites and search for information on the available web services. This information includes the technical programming interfaces (i.e., the WSDL) for interfacing with the business. The details about what kind of information you should store in a UDDI registry and the APIs that can be used to access this registry are documented in the specification, which can be found by visiting http://www.uddi.org/.

WebLogic implements the UDDI 2.0 specification. In fact, it comes equipped with three UDDI features:

  • A UDDI registry runs on every WebLogic instance, and can be used to store references to any web service.

  • A web-based UDDI Directory Explorer is distributed with your WebLogic installation. The UDDI Explorer lets you search and browse any UDDI registry on the Web, including any private UDDI registries running on WebLogic. Authorized users also can publish new services over WebLogic’s UDDI registry.

  • WebLogic provides a set of client APIs that allow you to programmatically publish and inquire about information stored in a UDDI registry.
