How to create a file from a rendition?

This can't be as hard as I seem to be making it, but I can't figure out how to get a rendition into a format I can work with. What I'm trying to do is locate pdf renditions and check to see if they in the PDF/A-1b standard. To do that I'm using Apache's PDFBox preflight to check the standard.

I need to pass PDFBox a File, a DataSource or a file name. So I need to grab the pdf rendition and make it into a file. The best I've been able to do is create a ByteArrayInputStream from the content, but then I'd need to go through the whole mess of creating a File from that. Isn't there an easier way?

Any help would be much appreciated.

getFileEx(null, <rendition format>, 0, false) will return a string with the path to the rendition.

so you can do somehting like:


String localPDFPath = sysObj.getFileEx(null, "pdf", 0, false);
PDDocument pdf = PDDocument.load(new File(localPDFPath));

THANK YOU!! I'd been messing around with the getFileEx, but just couldn't put it all together.

Since there might be more than one pdf rendition, I used the getFileEx2 method like this:

(doc is the parent IDfDocument)

IDfPersistentObject rendDoc = null;

IDfCollection contentTypes = doc.getRenditions("r_object_id");

while (contentTypes.next())

{

String rendDocID = contentTypes.getString("r_object_id");

rendDoc = sess.getObject(new DfId(rendDocID));

pageNbr = rendDoc.getInt("page");

pageModifier = rendDoc.getString("page_modifier");

String pdfFileName = doc.getFileEx2(null, "pdf", pageNbr, pageModifier, false);

File pdfFile = new File(pdfFileName);

... call routine to check for pdf-a here
