Hi,
we would like to render a PDF/A out of an xdp template and some xml formdata. The OutputService.generatePDFOutput(xdp, xml-data, PDFOutputOptions) should be the right api to do this. The specific adjustments to get a PDF/A should be handed over within the PDFOutputOptions object I assume.
The former LiveCycle api had a similar service but the paramerters are different. It supported settings like:
In the PDFOutputOptions I'm missing settings like that.
Can someone provide me with a code snippet or point me to some sample that does PDF/A rendering with the new AEM6 forms?
Thank's for any help on this!
Alex

Hi Alex,
In order to create PDF/A document you need to render regular PDF using OutputService.generatePDFOutput(xdp,xml-data,PDFOutputOptions) and convert resulting PDF to PDF/A using AssemblerService.toPDFA method.

Hi Nitin,
it sounds a bit cumbersome to me to render it first and transform it afterwards. So I thought there must be some other direct way like usage of specific settings in a xci-file. But if it is the recommended way to do two calls, we are happy to go for it.
Thank's for your quick response!

Hi,
I am trying to get the PDF/A transformation running, using the following code.
try { PDFAConversionOptionSpec conversionSpec = new PDFAConversionOptionSpec(); conversionSpec.setLogLevel("FINE"); conversionSpec.setResultLevel(PDFAConversionOptionSpec.ResultLevel.DETAILED); conversionSpec.setCompliance(PDFAConversionOptionSpec.Compliance.PDFA_1B); conversionSpec.setSignatures(PDFAConversionOptionSpec.Signatures.ARCHIVE_AS_NEEDED); conversionSpec.setColorSpace(PDFAConversionOptionSpec.ColorSpace.S_RGB); // Add PDFA Converter Schema String schemaPath = "C:/tmp/XMP_SCHEMA.xmp"; List<Document> metadataSchemaExtensions = new ArrayList<Document>(); Document schemaDoc = new Document(schemaPath); metadataSchemaExtensions.add(schemaDoc); conversionSpec.setMetadataSchemaExtensions(metadataSchemaExtensions); //conversionSpec.setRemoveInvalidXMPProperties(true); PDFAConversionResult pdfaResult = assemblerService.toPDFA(inputPDF, conversionSpec); Document pdfa = (pdfaResult != null) ? pdfaResult.getPDFADocument() : null; return pdfa; } catch (ConversionException e) { RenderServlet.LOG.debug(e.getClass().getName() + ": " + e.getLocalizedMessage()); e.printStackTrace(); }
If I use this with a simple flat PDF with only some text in it, I get this Exception:
com.adobe.fd.assembler.client.ConversionException: AEM-ASM-S02-001: The document named "docConverter.pdf" could not be opened.
If I do not use "setMetadataSchemaExtensions", a PDF/A document is generated, but our validation tool reports the missing schema and some other options.
How can I solve this problem or where can I find more information on this matter? Unfortionately the api docs contain nearly no explanations of any kind.
Any hint welcome!

Hi Nitin,
sorry, had some problems with the forum. First i had my former posting twice, then when I delete one, both were gone.
So here once again with the stack trace.

Hi Sebastian,
I could not make out much from this stack trace. Can you please attach the collateral with which you are facing this exception. I will have a look at it and reply accordingly.

Here is the complete RenderServlet code with the two necessary input files.
The URL we use:
http://localhost:4502/services/render?format=pdfa&xmp=c:/tmp/AEM/schema.xmp&xdp=C:/tmp/AEM/test.xdp

Hi Alex, Sebastian,
I think the issue is that the xmp file resides on file system and in the code
Document schemaDoc = new Document(schemaPath);
schemeDoc is being created using string argument constructor. This assumes the files is in repository. In order to specify a file which resides on files system use constructor with java.io.File argument as in
Document schemaDoc = new Document(new java.io.File(schemaPath));
Thanks

Hi Nitin,
Perfect! This is the solution to the problem!
Now I get valid PDF/A-1b.
thanks for the help!
