URL to get encoded format of a file : https://base64.guru/converter/encode/file

Selected a pdf file from my local system and click encode file to base 64 button to get encoded data of the file.

Created a sample activity VerifyWork, in that called an pega activity named View of Code-Pega-PDF class.

This activity use is to download the base 64 format pdf file .

For this activity we have to provide 2 parameters,

PDFName - in which name the pdf file should download

PDFDocument- base 64 format of pdf file.

Added Java step to decode base 64 into byte array.

Java code:

String S = tools.getParamValue("PDFDocument").toString();

byte[] byteArray =  new com.pega.pegarules.pub.util.Base64Util().decodeToByteArray(S);

tools.putParamValue("PDFDocument",byteArray);

Lets run the activity and verify our work.
