186 Broker Interactions for Intra- and Inter-enterprise
8.6.5 Define the services and filter to Web Services Gateway
Before you define a Web service to the Web Services Gateway, deploy the
resources (channels, filters, UDDI references and security bindings) that the
Web service uses.
1. Install the Web Services Gateway. The Web Services Gateway used in this
scenario was installed from and deployed on WebSphere Application Server
Enterprise V5.0.2 with the 5021 fix applied.
Once the application server and the Web services features have been
installed and brought up to the correct fixpack level, you will need to complete
the installation of the Web Services Gateway using the instructions in the
InfoCenter.
The Web Services Gateway is an enterprise application that runs on an
application server, so this process includes creating a database for the Web
Services Gateway to store data in, and installing the Web Services Gateway
applications. Scripts are provided to do this.
2. Perform the initial configuration of the gateway, including the namespace URI.
If you change the namespace URI, you break the link back to the Web
Services Gateway for every Web service that you have already deployed. So
you must set the namespace URI before you deploy any Web services.
3. Add a channel to handle incoming SOAP requests.
4. Add a reference to the UDDI Registry.
5. Deploy the Web services to the gateway. If you aren’t using a filter to route
service requests, you will need to create one service for each service provider
(InventoryWholesale1 and InventoryWholesale2). If you are using a filter to
route requests, you will only need to create one service, with two target
services (InventoryWholesale1 and InventoryWholesale2).
Initial configuration
1. Open the Web Services Gateway administration console at:
http://wsgw_host:9080/wsgw/admin/
2. Select the Configure option under Gateway.
3. Enter the following values (Figure 8-23):
– Namespace URI for services: urn:ibmwsgw. (default)
– WSDL URI for exported definitions: http://wsgw_host:port/wsgw
