Announcing Developer Day 2021!

Announcing PeopleSoft Developer Day! Join me online Thursday, August 19th for a full day PeopleTools experience filled with tips and best practices. Space is limited so register now!

Register Now!

Here are some of the topics we will cover and questions we will answer:

Configuration versus Customization

If you use Event Mapping, is that a customization or configuration? If you replace an AWE event handler, is that configuration or customization? Does it matter? Are there lifecycle consequences? How do you confirm a solution still works after applying maintenance?

PeopleSoft Test Framework

Another way to think of a configuration alternative to customization is as a runtime customization with no compare reports or lifecycle management tools. We will show you how to use PTF to regression test configurations.

PeopleCode Application Classes

Application Classes are the foundation for every modern framework including AWE, Integration Broker, and Event Mapping. We will cover the basics of Application Classes, and then use them to override Approval Framework behavior and to implement Event Mapping.

Event Mapping and Drop Zones

We will warm up with some simple Event Mapping and Drop Zone examples to describe them, and then show you some "what's possible" ideas in Fluid Job Data

Fluid

We'll cover Fluid layout techniques, specifically focussed on Drop Zones, and we'll also show how to create Dynamic Tiles, which also require Application Classes.

JavaScript

The PeopleSoft User experience is HTML, JavaScript, and CSS. We will show you some simple ways to combine JavaScript with Event Mapping to improve the user experience.

Integration

REST is the primary modern integration strategy, so we will cover a couple of simple REST examples, and then show how we can use REST with AWE to send text messages to requesters on final AWE approval.

Approval Workflow Engine (AWE)

We want to send notifications as text messages. To do so, we will have to extend AWE. How would you do this and is it a customization? Find out at Developer Day 2021!

App Classes or Function Libraries: Which is Better?

As programmers, we look for patterns. And when we find them, we refactor them into reusable code. Keep it DRY: Don't Repeat Yourself. PeopleCode offers two reusable code containers:

  • Function Libraries
  • Application Classes

And this brings us to the great debate. Which is better? Object-oriented App Classes or procedure-based Function Libraries? I often ask my students this question. And if they prefer one over the other, why? Let's review the benefits of each:

Function Library:

  • Stateless
  • Simple
  • Must be declared

Application Class:

  • Stateful
  • Dynamic execution

There are other differences, but they are irrelevant for this comparison. For example, Application Classes have inheritance (some would say inheritance is NOT a benefit). The value of inheritance is reuse, but then a function can call a function, which is also reuse.

When asking students about their preference, here are a few of my favorite answers:

  • Choose App Classes because they are new.
  • Choose App Classes because they are object-oriented.
  • Choose App Classes because we are supposed to.
  • Choose App Classes because everyone is doing it.
  • Choose Function Libraries because they work!

One of the most valuable features of App Classes is dynamic PeopleCode. Unlike Function Libraries, App Classes do not have to be imported/declared before use. This is how every PeopleTools framework works. As a developer, we create an App Class and register it with the framework. At runtime, the framework reads the metadata and invokes the App Class. A framework such as AWE, for example, knows nothing about my custom App Class. But it invokes my code nevertheless through functions such as CreateObject, ObjectDoMethod, ObjectGetProperty, and ObjectSetProperty.

Which one do I choose? Here are my decision criteria:

  • If I need dynamic PeopleCode, meaning no declaration, then the only solution is an App Class. Another way to think about it is if I'm writing code that invokes another code block and I don't know that code block at design time, but will fetch the name from the database, then I have to use an App Class.
  • If I'm writing code to plug into another framework, such as Event Mapping or Integration Broker, I will use an App Class.
  • If I want testable code to test through PSUnit, I will create an App Class (because PSUnit is a framework that will invoke dynamic code).
  • If I need to maintain state between method invocations, I'll choose an App Class.
  • Otherwise, I choose a Function Library.

Which do you prefer and why? What are other benefits of one over the other? Leave a comment to let us know what you think!

At JSMpros, we recognize the value of Application Classes and offer a two-day course dedicated to teaching object-oriented best practices. In fact, our next session starts on August 9, 2021. Register now!

Do You "Regression Test" Your Configurations?

Do you have customzations? Do customizations slow down selective adoption? The answer, of course, is "Yes" to both questions. Our best practice is to move customizations into configurations through Event Mapping, Page and Field Configurator, Drop Zones, etc. Configuration alternatives remove changes from lifecycle management, allowing us to alter the PeopleSoft experience without the impact and overhead of a customization... or do they? It is true; configuration alternatives don't show on compare reports. They move our "customizations" into a separate layer, a runtime injected layer, allowing Oracle to swap the backend code. Another way to think of it is that configuration alternatives automate applying customizations.

Let's review a quick scenario. Let's say there is a field on a page, and you are supposed to remove it. Simple task. The PeopleCode would be record.field.visible = False; If we customized, we would add that code to a design-time event, such as PostBuild. As a configuration, however, we would put that code in an App Class and then use Event Mapping to inject the code at runtime. So the value of configuration is that you don't have to reapply code changes. They are injected at runtime.

So here is a question:

When you re-apply a customization, is design-time code merge (copy/paste) the only thing you do?

Of course not! You also analyze. You investigate. Is the customization still necessary? Is it still relevant? Do you need to refactor around Oracle's changes? You still need to ask all of those questions. Even as a configuration, not a customization, you still must answer the same questions because it is the same code. It is the same solution. It solves the same problem. And, if you customized, you would have a compare report showing you what to review and where. Context. This is proactive. But with configuration? Silence. Without a compare report, how do you know what to review? How do you know what changed? Wait for testers to catch it? Wait for go-live? This is reactive.

Let's continue with the hidden field/Event Mapping example, and you go through a selective adoption or get current cycle. Since you used Event Mapping, your code is still there. But again, should you review it? How do you know what to review? What if Oracle agrees with our "hidden field" assessment and removes that field? Because we used Event Mapping, our code is still there, but it would refer to a field that is no longer in the component buffer, and will fail. What proactive lifecycle management tool is going to help you identify this issue? Without a compare report, how do you know what requires analysis? These are fantastic questions!

One way to locate conflicts is through regression tests. Each time I create a configuration (Drop Zone, Event Mapping, Page and Field Configurator, etc.), I record a test. That test proves my configuration still works. After each get current, I can run my regression test suite and see what fails. Test metadata will point to the change request, etc. so I know what to repair and where. I bet you are already doing regression testing. Everyone does. We usually call it "End User Testing." It might be a formal process but may not include change request documentation, etc. It is more like, "Hey, that thing that used to work is broken again." Alternatively, we recommend PeopleSoft Test Framework (PTF). The PTF metadata (comments, etc.) would contain the change request details. When the test fails, we can easily drill to the supporting documentation. This is proactive.

At this point, you might be saying, "We would LOVE to do that, but we haven't implemented PTF." But here is my question. Do you have to "implement" PTF to use it? Can't you, as a developer, just start recording regression tests against your configurations? That is what we recommend, and that is what we teach in our two-day PTF training course. You already have it. It's just waiting for you to start using it.

Our next PTF course starts in a couple of days, so be sure to register here ASAP! Or, purchase our On-demand PTF training course and get 60-days access to digitally mastered content to learn PTF whenever and wherever.

New to configuration? We regularly offer event mapping, drop zones, and Page and Field Configurator classes. Check out our website to see what we are offering next! Prefer On-demand? Take a look at our new On-demand Drop Zones course and learn on your own time.

Register Now!

Here are some of the topics we will cover and questions we will answer:

Classic versus Fluid

Both Classic and Fluid use App Designer to create solutions. Both support drag and drop page design. So what are the differences? And if you know Classic, what do I need to learn to be proficient with Fluid?

Mobile

Isn't Fluid mobile? If so, why aren't my grids responsive? What mobile-friendly options exist for grids?

Drag and Drop

PeopleSoft homepages allow us to drag and drop tiles. AWE allows us to drag and drop fields. How can I implement Drag and Drop on my own Fluid pages?

Branding

What does it take to create a branding theme for a PeopleSoft instance? How do you brand both Classic and Fluid? Do I have to use Branding Macros with Fluid? Are there alternatives?

Drop Zones

Where can I use Drop Zones? What can I do with them? What if a component doesn't have Drop Zones? Are there limitations with Drop Zones? Since Drop Zones and Event Mapping don't appear in compare reports, how do we know what to review after a system update?

PeopleSoft Test Framework (PTF)

How do you implement PTF? Are there any challenges to using PTF with Fluid? Are there special considerations for PTF with Event Mapping and Drop Zones?

Where do you terminate SSL for PeopleSoft?

Most PeopleSoft implementations have some sort of firewall/load balancer appliance in front of PeopleSoft. As an administrator, one question we have to answer is, "Where do we terminate SSL?" And the answer seems so obvious, most don't even ponder the question. What is the obvious answer? Terminate at the load balancer. Why? Because that is why they exist. SSL/TLS is what they do, and they do it well. What's the alternative? Carry SSL all the way to Weblogic, and terminate at the PeopleSoft web server. Weblogic is amazing at what it does, but it isn't a security appliance. And that is why the obvious answer is to terminate at the load balancer. But here is my question:

Are you reencrypting the traffic between the load balancer and PeopleSoft?

Do you encrypt all the way to Weblogic or do you terminate at the load balancer, thereby passing sensitive information in plain text behind the firewall?

Over the last several years I have heard fantastic security presenters recommend SSL termination at the load balancer level (for good reason). But they always end encryption at the load balancer. They don't encrypt behind the firewall. Why not? The most common reason is performance. Encryption isn't free. And if encryption is expensive, why encrypt behind the firewall? Here are two reasons:

  1. Your network might not be as secure as you think it is. A great example is NASA's breach implemented through a Raspberry PI.
  2. PeopleSoft-delivered service operations expect encryption.
As a developer, I defer to the network infrastructure design team. If they say the network is secure, I take their word for it. But take a look at reason #2. There are several PeopleSoft-delivered service operations that verify encryption at the Weblogic level. If I want to use those delivered service operations, I either need to:
  • Carry SSL/TLS all the way to Weblogic or
  • Modify the Service Operation.
Which would you prefer?
