Thanks for your response.

Can I set the Reader Extensions programatically after all the modifications?.

I am reading the files that has Reader Extensions applied to it from my app server and fill it with values and generate the modified PDF ByteArrayOutputStream.

Code Snippet:

try {

         // Read the input PDF file
         PdfReader reader = new PdfReader((String)object);

         // Instantiate a PdfStamper with a outputfile name specified
         PdfStamper stamper = new PdfStamper(reader, pdfStream);

         // Get all the AcroFields from the file
         AcroFields af = stamper.getAcroFields();

         // Iterate through the List of Value objects and set them in AcroField
         processFields(af, values);

   stamper.close();

   // Finally return the OutputStream to the client
   return pdfStream;
  } catch (Exception de) {
            de.printStackTrace();
            // Return null in case of errors
            return null;
  }

How would I change the workflow to apply the Reader Extension after the modification?

Also can you elaborate on your comment below

Would this resolve my problem?

Thanks

Correct. Because you did indeed modify it.

You need to switch your workflow so that all modifications
are done BEFORE the application of Reader Extensions.

You may also need to invest in Adobe's LiveCycle Reader
Extensions Server, if your requirements dictacte.
