Creating a New Provider Application Service
This topic provides the steps necessary to create a Provider Application Service.
Creating a Provider Application Service involves the following steps:
Create an Application Class that extends the PTCBAPPLSVCDEFN:ApplicationServiceBase application class and then implement the invokeService() method.%this.ServiceAPI property is the delivered API to read and write parameters, headers and access other metadata.
Create Application Service.
The General Information page defines the App Service ID, Service URL ID and a description. The Service Category is Provider.
Create or import a root resource.
Add URI templates.
Add base template parameters to URI Template.
Add method to URI template.
Add input and output parameters to method.
Optionally assign headers for the method.
Define result states for the method.
To create a new Provider Application Service:
Select .
Click Create Application Service.
This example illustrates the fields and controls on the Application Services – General Information page. You can find definitions for the fields and controls later on this page.

The Save action will perform the following:
Verify that the Service URL ID value meets the Oracle standard for an URL value. If valid, the value will then be checked against Integration Broker Service Alias's to insure it is unique. If the value does not meet this criteria, a pop up message will be displayed.
This example illustrates the Service URL ID validation message.
Correct the Service URL ID and save the application service.
When the Service URL ID is valid, save processing will generate the necessary IB metadata, update the Service Name and enable the Create Root Resource and Import Root Resource buttons.
This example illustrates the fields and controls on the Application Service page after Save. You can find definitions for the fields and controls later on this page.
