Generate QR code from Pega

-

This is a small experiment on how to generate a QR code using Pega. For this, we need a Zebra Crossing library(jar) to import into Pega and use those classes to create a QR code image (png) from Pega. It is available from the Maven repository given below (just use a browser to download it) and use the Import feature from Pega.  

https://repo1.maven.org/maven2/com/google/zxing/core/2.2/core-2.2.jar

The main steps we need to follow in Pega to work on this exercise:
1) Build a Pega function (RUF): GenerateQRCode  with the java code to generate the QR code image. This RUF needs few parameters like file type, text to use, width & height of the images.
2) Build another Pega function (RUF): GetFileName with the java code to get the random file name using SHA1 checksum of the image.
3) Build the logic in the activity: GenerateQRCode by using the above 2 steps and render the QR image in a HTML screen popup using Show-HTML from the activity.

Here is the snapshot of the activity with the above mentioned steps.

Image
Enable AI-powered access to your Pega Investigative Case Management data directly from Claude prompts using the Model Context Protocol (MCP) and OAuth 2.0. What is MCP and why connect Pega to Claude? The Model Context Protocol (MCP) is an open standard that lets AI assistants like Claude securely call tools and read data from external systems — all from a natural-language prompt. Think of it as a universal adapter between your enterprise systems and AI. Pega Infinity V25.1.3 ships with a first-class MCP service built on its existing REST framework. Once enabled, Claude can: Query and summarize investigative cases without switching apps Retrieve assignment details and case status on demand Trigger Pega workflows from conversational prompts Version requirement: This guide is based on Pega Infinity V25.1.3 (Community Edition) with the Rule-Service-MCP rule type. Earlier versions may not include native MCP support. Architecture overview The connection uses three layers: Claude as the AI c...

itextpdf API to generate PDF doc from an image file using Pega PE

-

Probably some of the techies might have an idea on an opensource called " itextpdf " (earlier name is lowagie ) to convert an image file(png,jpeg,jpg,tiff,gif etc.) to a PDF file. It is very simple to use this API in Pega function to build the logic using java code. Moreover, this API comes in one single jar file and we need to import it in Pega before we start using it.  I see the conversion comes good in PDF file but not sure if any limitations of this API in terms of conversion is like formatting, font, images etc. So far so good and may be we can keep this API as one of our solutions while working on the requirements accordingly.  Heard that same API can be used to convert the text file to PDF but I didn't explore on it. Those who are interested to work on text -> PDF can take a look at the documentation. Don't hesitate to contact me offline for any further discussion in this context :) :) Prerequisites for doing this exercise: 1) itextpdf 5.4.0 jar file 2) Peg...
