Create a zip file with multiple files in Pega V851 and is password protected too

-

 One of my friends came with a requirement like- Is there anyway we can create a zip file with multiple files from Pega? Also, he asked me to protect the final zip file after finishing the process .After digging a bit in the net, I got an opensource (zip4j) since we don't find a direct OOTB feature for this usecase. This opensource was built by Srikanth Lingala and is based on pure java. There might be other opensources to create a zip file in the market but this one provides security on the final zip file. This opensource comes with a single jar file to import in Pega to get all necessary files to work on this exercise.

Here is the link to download the jar file: https://jar-download.com/artifacts/net.lingala.zip4j/zip4j/1.3.2/source-code 

As usual, I created a simple Pega function with the java code by importing the necessary packages in the library rule. Called this Pega function from a Data Transform and tried with 2 files and created a pwd protected zip file after running the DT. As a part of PoC work, kept all the files in my /tomcat/temp/Misc folder. Here is a sample screenshot for this exercise. The next steps for him could be like he needs to build the Pega UI to capture the files and start using this function from his env.

The below Pega function needs a parameter with ZipFileName and the return value is a string of Success/Fail. Logic is simple. Pass the files in parameters from the DT and construct the path in tomcat to create a zip file in the same path using the java code. All the steps are clearly documented in the code to implement independently. Feel free to contact me offline.

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...
