Hi, I am trying to create to convert base64 encoded pdf document to com.adobe.aemfd.docmanager.Document object by using below line of code. But it throwing error. Any suggestion please.

Document document = new Document(Base64.decodeBase64(base64));

Errors:

There is no constructor to create document from base64 in AEM forms OSGi

@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

<dependency>
<groupId>com.adobe.aemfd</groupId>
<artifactId>aemfd-client-sdk</artifactId>
<version>6.3.0</version>
</dependency>

and it did work.

What version of AEM Forms are you using?

Wells_SriAuthor

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
