@GirishBedekar he is decoding it in the call.


But I wonder which Base64 class that is. The Oracle JDK class is defined here https://docs.oracle.com/javase/8/docs/api/java/util/Base64.html

Are you sure that a byte array is passed? Sure that the base64 variable decodes to a proper PDF?

Did you try to have the decoding separate like

byte [] thePdfDocument = Base64.decodeBase64(base64);

Document document = new Document(thePdfDocument);

I am using Java Util package. Yes, Byte array passing to as a parameter. 

I am getting same error message when using below code as you recommended. Thanks


String baseDoc = "......";

Base64.Decoder decoder = Base64.getDecoder();

// Decoding string String dStr = new String(decoder.decode(baseDoc));

Document document = new Document(dStr.getBytes());



I see you posted also in another thread.


I tested this with AEM Forms 6.5.7 using 


and it did work.


What version of AEM Forms are you using?

No, I am getting same error earlier and now using recommended dependency. I have tried with both version 6.3.0 and 4.1.50
