CODE SEGEMENT Follows.... EslClient eslClient = new EslClient( API_KEY, API_URL ); InputStream myPDF = null; myPDF = Hello.class.getResourceAsStream( "/Consent.pdf" ); DocumentBuilder db = DocumentBuilder.newDocumentWithName("Consent"); db.withDescription("Sample Consent Document"); db.fromStream(myPDF, DocumentType.PDF); db.withSignature(sig); Document d1 = db.build(); PackageBuilder pb = PackageBuilder.newPackageNamed("Don Sample Package Friday Oct 16"); pb.withSigner(s); pb.withDocument(d1); DocumentPackage dp = pb.build(); PackageId id = eslClient.createPackage(dp); eslClient.sendPackage(id);
