I am using adobe LiveCycle 8.2 to convert PDF documents to PDF/A.
I tried this in two ways.
First I used the toPDFA method of the DocConverterService. In that case most of the pdf-documents could not be converted.
In another case I used the toPS method of the ConvertPdfService to convert the file to PostScript and then the createPDF method of the DistillerService service to go from PostScript to PDF/A. When I open the converted files in Adobe Reader 9, I get the message "You are viewing this document in PDF/A mode", but when I check the document with the isPDFA method of the DocConverterService then in most cases the document is not PDF/A compliant. When I use toPDFA method on this document it can be made PDF/A compliant.
What is the preferred way to convert PDF to PDF/A?
When is a document PDF/A compliant? When Adobe Reader says it is, or when LiveCycle says it is? And if Adobe Reader is right, Is there a way to check compliance with LiveCycle?
