# Registering with a UDDI registry

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 private registries with which you can register. Since each registry is different, the registry provider will give you instructions for registering.

The following registries are automatically added to Favorites:

- SAP UDDI Registry
- SAP UDDI Test Registry
- XMethods Registry
- NTT Communications Registry

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. The details page of each registry will have registration instructions.

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.
