PeopleSoft has been increasingly adding new ways to modify it's software without intrusive customization. One was is Event Mapping. This allows code to be placed in a application package and change the behavior of pages. These "maps" are tied to components.  Here's a simple example.  1. Create a custom Application Package From Application Designer. Go to File -> New -> Application Package Save it and give it a name Right click on the package and select Insert App Class   Give the class a name Double click to enter PeopleCode Editor Create a class the extends PT_RCF:ServiceInterface An application class for event mapping must import and extend the PT_RCF:ServiceInterface class. In addition, it must define a single method named execute . In this example the class is named make_links_clickable import PT_RCF:*; class make_links_clickable extends PT_RCF:ServiceInterface    method execute(); end-class; Now create the method method execute    /+ Extends...

PeopleSoft is moving more and more to developing in application packages. Event Mapping uses application packages, REST services use application packages, Fluid pages use application packages, and work centers use application packages. So it is prudent that developers know how to code classes and methods. This blog is to help you get started. A Class An extensible program-code-template for creating objects. It's where you define initial values for state (member variables) and implementations of behavior (member methods).  Class Wikipedia It defines a set of properties and methods that are common to all objects of one type. It short, describes the contents of the objects that belong to it. Class simple English Wikipedia For example a class could be a mountain bicycle. It could have color fields, speed fields, break fields, tire fields, etc. A road bike could be related to the mountain bike class. A road bike would have similar fields to a mountain bike class but not exactly the same...

But how do we do that with PeopleSoft This Blog will give you an example. 1st we need JavaScript Library to Scan both QR and Barcode InstaScan (only did BarCode) https://github.com/schmich/instascan Zxing (did both)  https://github.com/zxing-js/ Great libraries exist, but how do we get that into PeopleSoft? We'll need to add video/camera to Mobile Inventory Pages.  Can this be added? Will the page be able to access the camera? The answer is in PeopleSoft PeopleTools Tips & Techniques by Jim Marion Chapter 6 JavaScript for the PeopleSoft Developer JavaScript Libraries, pages 240-241 IScript/Messages Step 1 Get mimified version of Zxing https://unpkg.com/@zxing/library@0.14.2/umd/index.min.js PeopleTools -> Utilities-> Administration-Message Catalog Add Minified Code to Description Yes, you are correctly seeing that. Store the code in the message c...

PeopleSoft Rest Service     Here is a step by step example of how to create a REST service in PeopleSoft.  The first example passes one row of data via the URL. The response includes multiple po lines.  The second example passes JSON in the body with no parameters in the URL.
