Web Services Description Language (WSDL) is essential in creating web services as it provides a standard way to describe the functionalities offered by the service. Integrating WSDL with PeopleSoft can facilitate communication between your PeopleSoft applications and other web services. This article outlines how to build a WSDL using PeopleCode with a Component Interface (CI), allowing you to harness the power of web services in your PeopleSoft environment.
Understanding the Problem Scenario
The original problem scenario involves creating a WSDL that interacts with a Component Interface in PeopleSoft. Here's a simplified version of the requirement:
Original Code Problem: How do I create a WSDL for a specific Component Interface using PeopleCode?
In essence, the task is to generate a WSDL for a pre-defined CI to enable seamless web service communication. This can be particularly useful in situations where you need to expose a PeopleSoft application functionality to external applications.
Steps to Create a WSDL in PeopleSoft
Below, we detail the steps to create a WSDL in PeopleSoft using PeopleCode along with a Component Interface.
Step 1: Create the Component Interface
Before we can generate a WSDL, we need a Component Interface. Here’s how to create one:
- Log into PeopleSoft Application Designer.
- Navigate to
File->New->Component Interface. - Define the Component Interface:
- Give it a name and associate it with an existing PeopleSoft component.
- Set the necessary properties and make sure the Component Interface is “Public” so it can be accessed externally.
Step 2: Define the WSDL for the Component Interface
Once you have your CI ready, you will need to generate a WSDL for it. Here’s an example of how you might write the PeopleCode to accomplish this:
Local string &wsdl_name;
Local string &base_url;
&wsdl_name = "MyComponentInterface";
&base_url = "http://yourserver/yourapp/wsdl/";
Local string &full_wsdl_url = &base_url | &wsdl_name;
If GetWSLD(&full_wsdl_url) Then
/* Logic to retrieve the WSDL, and handle it */
Else
/* Handle errors */
End-If;
Step 3: Expose the WSDL as a Web Service
To expose the WSDL created from your CI, perform the following:
- Navigate to the
Integration BrokerSetup. - Register the Service:
- Use the service operation wizard to register the CI as a web service.
- Choose the appropriate parameters and ensure your service is active.
- Test the Web Service:
- Use tools like Postman or SoapUI to test the WSDL and confirm that it returns the expected XML data.
Analysis and Additional Explanation
Building a WSDL for a Component Interface in PeopleSoft is a straightforward process but requires careful configuration to ensure it communicates effectively with other systems.
Why Use WSDL?
WSDL is XML-based and provides a clear and formal description of the web services. This makes it easy for developers to understand the operations, input parameters, and data types without diving deep into the code. It serves as an interface definition, bridging the gap between various platforms.
Practical Example
Imagine you have an HR system built in PeopleSoft, and you want to expose its employee data to a third-party application for reporting. By creating a WSDL for the relevant CI, the third-party application can consume it and use the employee information seamlessly, enhancing collaboration and data sharing.
Conclusion
Creating a WSDL using PeopleCode with a built Component Interface is an excellent way to extend the capabilities of your PeopleSoft applications. It facilitates integration with external services and supports the modern architecture of applications.
