1. Create a Custom Activity: Create a custom activity in your application ruleset. You can name it something like ValidatePDF.

2. Use PDFBox Library: Utilize the Apache PDFBox library to validate the PDF file. You can add the necessary PDFBox JAR files to your Pega application.

3. Java Step in Activity: Add a Java step in your custom activity to perform the validation. Here’s an example code snippet using PDFBox:

   import org.apache.pdfbox.preflight.parser.PreflightParser;
   import org.apache.pdfbox.preflight.parser.ValidationResult;
   import org.apache.pdfbox.preflight.PreflightDocument;
   import org.apache.pdfbox.preflight.exception.SyntaxValidationException;
   
   public boolean validatePDF(String filePath) {
       ValidationResult result = null;
       try {
           PreflightParser parser = new PreflightParser(new File(filePath));
           parser.parse();
           PreflightDocument document = parser.getPreflightDocument();
           document.validate();
           result = document.getResult();
           document.close();
       } catch (SyntaxValidationException e) {
           result = e.getResult();
       } catch (Exception e) {
           e.printStackTrace();
       }
       return result != null && result.isValid();
   }
   

4. Call the Custom Activity: Call this custom activity during the file upload process to validate the PDF file. If the file is corrupted, you can handle the error accordingly.

5. Handle Validation Result: Based on the validation result, you can display an appropriate error message to the user if the PDF file is corrupted.

Example Activity Steps

1. Step 1: Java

   • Method: Java
   • Java Code: (Insert the PDF validation code here)

2. Step 2: Property-Set

   • Method: Property-Set
   • Properties: Set a property to indicate the validation result (e.g., IsPDFValid).

3. Step 3: Error Handling

   • Method: (Use appropriate error handling methods)
