With PI 7.1 is it possible to publish services to the Service Registry (SR) directly from the Enterprise Service (ES) Builder and Integration Directory. The publishing functionality will allow developers and Business Process Experts (BPXs) to publish the services interfaces to the SR or UDDI. The UDDI will then contain a global list of all the services, which is implemented or at some point will be implemented.
To show the different ways to define services, it is necessary to see how they can be published. Services can be provided the following ways.
- Brokered Service implemented in own system. A service provided by your company is exposed as a web service in your PI system (a brokered service) and the endpoint is made available via the SR.
- Brokered service to be implemented in partner system. A new interface must be developed. It will be implemented as a web service provided by a partner system. You want to offer this service in your own SR. You define the interface in your ES Builder and create a WSDL which the partner will use to develop and implement the service. When the service is deployed the endpoint can be posted in your SR.
- Web service provided by 3rd party. Someone has developed a webservice. The WSDL and endpoint can be published in your SR thus making the service available to users (developers) of your SR.
How can the ES Builder and SR be used to support the three different options? This will be described in the sections below.
