Publishing a web service to a UDDI registry

When you configure an inbound or outbound service, you enable UDDI interaction by associating the service with a UDDI reference, and (depending upon what you are trying to do) either or both of the following pieces of information: The business key that identifies the UDDI business category under which we want our service to appear in the UDDI registry, and the service-specific part of the service key the UDDI registry assigns to your service. To help you understand what UDDI business keys and service keys are, and where you find them in a UDDI registry, here is a description of how to publish a web service to a UDDI registry. Service integration technologies interact with UDDI registries as described in UDDI registries: Web service directories that can be referenced by bus-enabled web services. When you publish a web service to a UDDI registry, you:

• Specify the type of business that the web service supports. This usually means choosing an existing business type from a list, but we can also create a new business type. For each type of business there is an associated business key. Service integration bus-enabled web services use this key, in combination with the service key, to find the web service in the registry.

• Add a Technical model. Technical models are generic categories. Using these models, a UDDI registry user can search for a type of service, rather than needing to know the access details for a specific service. Bus-enabled web services interact with UDDI registries at the level of individual Web services, and therefore do not use Technical models.

• Add the web service. The UDDI registry assigns a service key to your service, and publishes the service. Bus-enabled web services use this key, in combination with the business key, to find the web service in the registry.

The following steps describe how you publish a web service to the IBM WebSphere UDDI Registry. If you are working with a different UDDI registry, then the specific navigation is different but the underlying principles are the same.

1. Specify a business:
   1. To get a list of valid business keys, look up businesses in the UDDI registry. Here is an example of a UDDI business key:
      08A536DC-3482-4E18-BFEC-2E2A23630526
      .

   2. If we do not find an appropriate existing business in the UDDI registry, then use the Add a business option on the Advanced Publish section of the Publish pane to add a new one.

2. Add a technical model:

   1. Select Add a technical model on the Advanced Publish section of the Publish pane.

   2. Enter the name as specified for the target namespace of your binding (or interface) WSDL file, then add a description (if required).

   3. Add a category of Type unspsc and value wsdlSpec (the Key name field can be left blank).

   4. Add an overview URL specifying the web address for the binding WSDL file, then add a description (if required).

      The binding and the service definition for the web service might be held in separate WSDL files, therefore be careful to type the web address of the WSDL file that defines the binding.

   5. Click Publish Technical Model.

3. Add a service:

   1. Select Show owned entities on the Advanced Publish section of the Publish pane.

   2. Select Add a Service for the business.

   3. Enter the name as specified for the target service in your WSDL file, then add a description (if required).

   4. For the Access point verify the correct web address type is selected (for example http for an HTTP access point), then enter the value of the soap:address location (or its equivalent) from your service definition WSDL file (for example http://yourhost:80/SimpleTest/servlet/rpcrouter).

   5. For the Technical model select Add, then find the required Technical model by entering a suitable prefix and selecting Find technical models, then select the check box for the required Technical model and click Update.

   6. Click Publish Service.

Results

The UDDI registry assigns a service key to your service, and publishes the service.

After the service has been published we can get the service key from the target UDDI registry.

Here is an example of a full UDDI service key:

uddi:blade108node01cell:blade108node01:server1:default:6e3d106e-5394-44e3-be17-aca728ac1791

The service-specific part of this key is the final part:

6e3d106e-5394-44e3-be17-aca728ac1791
