In order to publish your business entity and Web service to a UDDI registry, you must first register with the registry that you want to use.
There are many different public and private registries with which you can register. For a list of public registries refer to www.uddi.org/register.html Since each registry is different, the registry provider will give you instructions for registering.
The following registries are automatically added to Favorites:
You can use any of these registries by selecting the Favorites icon in the Web Services Explorer toolbar. All of these registries are based on the UDDI Business Registry Version 2. Go to the following URL to obtain a user ID and password for the IBM UDDI registry: www.ibm.com/services/uddi/. The details page of each registry will have registration instructions.
The IBM UDDI Test Registry allows you to develop your Web service and experience the UDDI registration process without placing your Web service in an official registry. Use the IBM UDDI Test Registry or a private registry to experiment with UDDI, and to test and validate your Web service. The public production registries are listed under Favorites. The Web Services Explorer does not preload any registries by default. You can preload registries from the favorites section of the Web Services Explorer or by using the Unit Test UDDI wizard. You can also preload and configure private registries using the Unit Test UDDI wizard. On the Open Registry page of the Web Services Explorer, you can select from public registries and registries listed in your favorites to automatically fill in the information required to open a particular registry.
