ascii coding in mime-type of attachment

[filippo.gatto]

Hi!
I'm using a "Spire.PDF for JAVA" v. 9.2.1 with commercial license (bought on last March 2023)
I'm trying a simple app with the follow java code (my IDE is using JDK jdk 1.8.0_211) for create a PDF/A with an xml file attached.
When I try to set the mime type "application/pdf" in the resulting file will have set the /Subtype "/application#2Fxml" instead of the expected /Subtype "/application/xml".
This is my code:

PdfDocument pdfDoc = new PdfDocument();
pdfDoc.loadFromFile(inputPdfPath);

//Read file to attach:
byte[] attBytes = Files.readAllBytes(Paths.get(attachmentPath));

//Create attachment:
PdfAttachment attachment = new PdfAttachment("cda.xml", attBytes);
//Set mime-type:
attachment.setMimeType("application/xml");

//Add Attachment to pdf
pdfDoc.getAttachments().add(attachment, pdfDoc, PdfAttachmentRelationship.Data);


The issue is similar to what is reported in this other topic:
mime-type-of-attachment-encoding-t10374.html

With "Spire.PDF for .Net" v. 9.2.2 the mime-types appear correctly.

Have you any suggestion about how to solve this issue?

Hello,

Thank you for your inquiry.
I did a preliminary test based on your description. Some of the PDFA result files reproduce the issue you mentioned. But I still want to confirm with you that your result files are PDF/A1A, PDF/A2A or other PDFA type documents. Please let me know clearly. Thanks in advance.

Hi Annika, I'm using "PDF/A-3A" pdfa type (converter.toPdfA3A). I attach an example of pdf/a-3a produced.

I reproduced the issue of incorrect MIME-TYPE after parsing PDF documents of type PDF/A3A embedded in xml attachments. I have logged the issue into our bug tracking system with the ticket number SPIREPDF-6542. Our development team will investigate and fix it. Once it is resolved, I will inform you in time. Sorry for the inconvenience caused.
