Hello team,
I am trying to utilize the DocAssuranceService to encrypt PDFs. I have created a class using the Sample 1 under the Securing Documents section here:
https://experienceleague.adobe.com/docs/experience-manager-64/forms/use-document-services/aem-docume...
Additionally, I have a servlet identical to the below link, which calls the above class in order to retrieve a certified PDF.
I have put a snippet of the class I have created to use the DocAssurance.
public class PassEncryptCertifyExtend {
@reference
private DocAssuranceService docAssuranceService;
@reference
private SlingRepository slingRepository;
@reference
private ResourceResolverFactory jcrResourceResolverFactory ;
/**
*
* @Param inputFile - path to the pdf document stored at disk
* @Param outputFile - path to the pdf document where the output needs to be stored
* @throws Exception
*/
Document outDoc;
Logger logger = Logger.getLogger("classname");
public Document SecureDocument(Document inDoc) throws Exception{
try {
logger.info("***** CALLING ENCRYPTION OPTIONS *****");
outDoc = null;
outDoc = docAssuranceService.secureDocument(inDoc, getPassEncryptionOptions(), null, null, null);
logger.info("***** EXITING ENCRYPTION OPTIONS *****");
} catch(Exception e) {
logger.error(e);
}
return outDoc;
}
outDoc = docAssuranceService.secureDocument(inDoc, getPassEncryptionOptions(), null, null, null);
This line is providing a nullpointer exception when run. I can verify that the inDoc being passed is without any issues. In addition, thegetPassEncryptionOptions() method is being run successfully. I have tried various options such as just passing inDoc with other parameters as null, passing in with all other parameters, yet all variations return a nullPointer exception. The logger indicating the exit of the docAssuranceService.secureDocument does not run and the code returns back to the servlet. I was wondering if I could receive any guidance in this regard.
Error:

you can get the sample resolver from this link. You will have to deploy the bundle and add the user mapper settings as shown in the document
hmmm
one last option - can you create your own developingWithServiceUser bundle and use it. The entire code is listed here
Hello,
Thanks for your comment. I had also tried this but it uses the same import which is providing the "import cannot be resolved" errors. The example code similarly uses the
com.mergeandfuse.getserviceuserresolver.GetResolver
This uses the GetResolver which comes from the zip file attachment from Step 1 in that link (the zip file is the same DevelopingWithServiceUser bundle.
