Hi,
I’m converting from html to pdf using Java (Using pd4ml 4.0.10 in maven):
For eg:
public static void convert(String inputFile, File output) throws InvokeException, IOException { PD4ML pd4ml = new PD4ML(); PageSize pageSize = new PageSize(600, 842); pd4ml.setPageSize(pageSize); PageMargins pageMargins = new PageMargins(70, 36, 56, 36); pd4ml.setPageMargins(pageMargins); File file = new File(inputFile); FileInputStream is = new FileInputStream(file); pd4ml.readHTML(is, null, StandardCharsets.UTF_8.name()); FileOutputStream outputStream = new FileOutputStream(output); pd4ml.writePDF(outputStream, "pdf"); }

Html for the footer:
<pd4ml:page.footer scope="1"> <section class="export-page-footer"> <tr > <td class="right"> <span class="pagenum">pag. $[page]</span> </td> </tr> </section> </pd4ml:page.footer>

Still shows me as:
pag. 1 for all pages from 10-19, after pag.9
and pag. 2 for all pages from 20-29, etc..

Any help would be appreciated.

Hi,

This issue is not yet fixed in 4.0.10 and still persists in 4.0.13. Is there any plan to fix?

Thanks,

So I have been using pd4ml for a long time. We mainly use the render method and pass it a url for the jsp in question. There are times we use the OutputStream of the HttpServletResponse, and sometimes we Use a FileOutputStream and save a pdf on a file system. It was just brought to my attention that the pdf files are being created and are blank. They are about 2K in size instead of 600-700K. PDFs in the Browser are just fine. These PDFs were being written to a File Server directly. I decided to try to write locally on the web server to a temp folder and then copy. On my local machine that worked just fine. But when I promoted to my DEV server, the file being written to the temp folder was blank.

This is PD4ml v.3, running on Tomcat9, Java 8. My local workstation and dev server are pretty close version-wise, although I am running Eclipse and a local Tomcat instance in that, and the dev server is running the Tomcat Service Wrapper. But both are Tomcat9, Java8, etc. Any ideas why it would run ok on my instance, but not DEV?

I did upgrade from Tomcat7 recently, so that could be related, but then I shouldn’t be able to work on my local instance. I can’t revert Tomcat to v7 for security reasons, and would think this should be able to work given it works for my local instance. Any help is appreciated!

Hi!
Please enable debug mode of PD4ML and inspect the server logs for possible PD4ML error messages or diagnostic output.
Also please open the generated 2K PDFs in a text editor and copy-paste its content to the thread to be reviewed. Thanks!

I was able to fix this. It ended up being an HTTP/HTTPS issue. It was something I fixed in a few spots months ago, but apparently missed one. I am able to make sure the url is HTTPS and it is all good.

Glad the issue is solved!

Hello,

Is there a possibility to set metadata (Title, LANG) for PDF UA feature through PD4ML api rather than in the content of HTML?
I’ve found a sample where this data is passed in HTML tags. I’m trying to use PD4ML.addMetadata(“lang”, “DE-de”, false) method but it seems does not change language metadata.
Could you please suggest an option?

Thanks,
Nina

#34757

Hi Nina,

the title can be set with void setDocumentTitle(String title) API call. But with lang it is a bit more tricky.

Try the following:
pd4ml.addStyle("HTML, BODY {lang: DE-de !important}", true);

#34769

Thank you, it works!
One more question, is that possible to set other metadata values (Subject, Keywords, Creator, Producer, CreationDate, ModDate and Trapped) using something like PD4ML.set*** similarly to setDocumentTitle() and setAuthorName()? I cannot find corresponding methods for these fields in the PD4ML class api.

#34772

See addMetadata() Javadoc

The method updates PDF’s XMP metadata.

Note, that date may appear in PDF in two different formats.

XMP metadata: “2009-11-27T18:25:45+01:00”
PDF info object: “D:20091127182545+01’00′”

So you’ll probably also need to call pd4ml.setParam(Constants.PD4ML_DOCUMENT_DATE, "D:20091127211216+01'00'"); to keep the doc dates in sync

Hi, please note that I just installed my license pd4ml-4.0.13.jar but I cannot see the spanish accent characters.
See attached. It states ‘Cotizaci?n’ instead of ‘Cotización’ (this is the spanish word for Quotation)

Thank you for your help.

addMetadata() tells that I should not use keys for standard properties:

key – a unique name, which must not be one of the standard property names Title, Author, Subject, Keywords, Creator, Producer, CreationDate, ModDate and Trapped

So, could you please confirm that I can use addMetadata() method to set these properties?

#34776

Hi! Most probably you did not configure TTF embedding.
See https://pd4ml.tech/pdf-fonts/

#34777

Sorry for the misleading hint. You are right, addMetadata() is a wrong way.

PD4ML allows to override “Creator” via environment variable:
System.getProperty( “pd4ml.creator.application”, cLogo );

“Author”
“Keywords”
“Subject”

can be set in <head> section of HTML with i.e <meta name=”Keywords” content=”test meta”>
