Overview of Publishing and Finding Web Services

The Universal Description, Discovery and Integration (UDDI) specification defines a standard way to describe a Web Service, register a Web Service in a well-known registry, and discover other registered Web Services.

Weblogic Server provides the following UDDI features:

• A UDDI 2.0 Server
• A UDDI Directory Explorer
• A UDDI registry
• An implementation of the client-side UDDI API so you can programmatically search for and publish Web Services

The UDDI Directory Explorer allows authorized users to publish Web Services in private WebLogic Server UDDI registries and to modify information for previously published Web Services.

The UDDI Directory Explorer also enables you to search both public and private UDDI registries for Web Services and information about the companies and departments that provide these Web Services. The Directory Explorer also provides access to details about the Web Services and associated WSDL files (if available.)

The UDDI 2.0 Server

To be written.

Points to include:

• is part of WLS
• is automatically started when WLS is started
• implements UDDI 2.0 server specification
• typically folks don't have to configure it; however, if you do, go to :

http://localhost:7001/uddi/admin/index.jsp

Invoking the UDDI Directory Explorer

To invoke the UDDI Directory Explorer in your browser, enter the following URL:

http://host:port/uddiexplorer

where

• host refers to the computer on which WebLogic Server is running.
• port refers to the port number where WebLogic Server is listening for connection requests. The default port number is 7001.

You can perform the following tasks with the UDDI Directory Explorer:

• Search public registries
• Search private registries
• Publish to a private registry
• Modify private registry details
• Setup UDDI directory explorer

For more information about using the UDDI Directory Explorer, click the Help link on the main page.

Using the UDDI Client API

Use the UDDI client API in a Java client application to search for and publish Web Services.

The two main classes of the UDDI client API are Inquiry and Publish. Use the Inquiry class to search for Web Services in a known UDDI registry and the Publish class to add your Web Service to a known registry.

WebLogic Server provides an implementation of the following client UDDI API packages:

• weblogic.uddi.client.service
• weblogic.uddi.client.structures.datatypes
• weblogic.uddi.client.structures.exception
• weblogic.uddi.client.structures.request
• weblogic.uddi.client.structures.response

For detailed information on using these packages, see the UDDI API Javadocs.

For examples of using the UDDI client API, go to the Web Services dev2dev Download Page and scroll down until you find the following examples:
