I just recently completed a project that heavily integrated with PeopleSoft. I have been on several projects and demos in the past that have integrated with PeopleSoft and figured it was time to share a little knowledge about how to do it.
The PeopleSoft Component Interfaces (CI) is a great way to integrate because it allows you to reuse all of the business logic and data validation that is used by the PeopleSoft Web interface. The version of PeopleSoft that you are integrating too will define the way you can call the CIs.
If you are lucky enough to be integrating with PeopleSoft 8.4 or greater, the CIs can automatically generate Web Services (as well as Java and COM objects) out of the box. This makes integrating with the CIs quick and easy since most integration tools can easily call Web Services. The only thing you need to worry about it getting the right data into the right fields.
If you are on an older version of PeopleSoft (pre 8.4) the CIs can be exposed as Java classes or COM objects. Since I mostly work with Java based tools for integration, we obviously used the Java classes. There are two ways to utilize the Java classes:
1.) Purchase the PeopleSoft Adapter from IWay. This exposes the CIs as Web Services that are easily called by any integration tool. The adapter is not the easiest thing to configure but once configured it makes integrating into a large number of CIs quick and easy. The adapter is costly so the ROI should be looked at before making the decision.
2.) Creating your own Web Service that utilize the Java classes exposed by the PeopleSoft CIs. This sounds like a lot of work but is actually pretty simple with a little knowledge of Java, PeopleSoft and a handy tool that will create a Web Service for you. We made use of the JAX-B framework and Oracle JDeveloper to quickly create these Web Service wrappers. Once the Web Services are created they can be integrated using most integration tools.
If you are starting off slow and only integrating to a handful of interfaces the second option might be most cost effective, but if you plan on integrating with several CIs (10+) it would probably be more cost effective in the long run to purchase the PeopleSoft adapter.

Good info. I would like to know if this feature is available in 8.4 and how to do this.
How you expose CIs depends more on your PeopleTools version. If you are on PeopleTools 8.46 or newer you can automatically create Web Services around any CI.
If you have an older version of PeopleTools you can create Web Services around CIs in a couple of ways:
1.) Use a JCA PeopleSoft adapter (iWay is the defacto standard)
2.) Create the Java or .NET API classes and write your own Web Service wrapper.
I hope this is the information that you are looking for.
Great info. How do you invoke external web services from within Peoplesoft ? Do you have to write code to do that or there is a standard configurable way to do it?
I would also be very interested to know if there is a simple way to call a web service from peoplesoft - particularly for passing a file to that web service as an argument.
Any information you can provide on how to invoke an external web service from Peoplesoft would be much appreciated.
You can call an external Web Service through the PeopleSoft Integration Broker tool. This is normally accomplished by capturing an event in application messaging and then calling out from there to the external service. Exposing the Web Service to Integration Broker is fairly straight forward, for PeopleSoft people. :)
Hello
