Could you please also publish an HTML snippet, you want to apply the CSS to.

Also, to make sure the CSS selector does not work, try to temporarily add any obvious CSS property, like “color: red”.

The HTML page, I want to apply the CSS to is generated by using JSF and Primefaces.

Moreover, I’m quite sure that the CSS is not applied because the cell border doesn’t appear.

#28482

It seems the exception is thrown by an image colorspace processing. Can you please temporarily comment images out from the document? Does it help?

If yes, it would be nice if you send us the images that cause the problem.

#27475

In the HTML I see no any element of class ui-datatable-data-empty, so the selector always returns nothing.

If your concern is about borders of empty cells, it can be solved with

TABLE { empty-cells: show }

I made a mistake. The CSS part is the following:
[language=css:2u9e9msa].ui-datatable .ui-datatable-data td, .ui-datatable .ui-datatable-data-empty td{
border-color:inherit;
border-style:solid;
border-width:1px;
padding: 4px 10px;
}[/language:2u9e9msa]
With this one, it should work.

#27477

PD4ML does not support

tag. It simply ignores it.

So TBODY.ui-datatable-data condition makes the selector to fail.
As a workaround I would recommend to remove .ui-datatable-data from there.

[language=css:2o5v2soz].ui-datatable td, .ui-datatable .ui-datatable-data-empty td{
border-color:inherit;
border-style:solid;
border-width:1px;
padding: 4px 10px;
}[/language:2o5v2soz]

Here is the issue. Ok, I’m now able to correct it. Thanks a lot for your help.
Moreover, we use the 3.5.1 professional version. If we want update to the 3.7.0 one, do we have to pay it?

#27479

It depends on the issue date of your license. Please contact sales pd4ml com

I tried the option -pdfa on a command line:
export CLASSPATH=/home/castiler/Pd4ml/pd4ml_demo.jar:/home/castiler/Pd4ml/ss_css2.jar
java -Xmx512m -Djava.awt.headless=true -cp pd4ml_demo.jar Pd4Cmd ‘file:NOUVEL-AVIS-ADRESSE.html’ 1200 -pdfa -out NOUVEL-AVIS-ADRESSEv370.pdf

But i have this error when pass the pdf in “pdf validator”, ihave this error:

What can i do to have a valid pda/a ?

#28173

There is no PDF/A-capable evaluation version of PD4ML available for download.
Please contact support pd4ml com to get one.

#28483

hello

yes the cause is an image with extention PNG .. but why its not accepting PNG images

thanks

#28484

I did not wrote it accepts no PNG. Normally it has no problems with PNGs. But it could be that:
1. your particular image has corrupted colorspace information
2. there are bugs in the recent application update (the development build you evaluate did not pass QA yet).

#28485

Hi anas_srairah,
can you give me an example of how I would use use PDF class in a servlet?

#26535

hello

i have a problem parsing png images … please let me know how to solve it

thanks

#28486

hello

here is an example servlet that uses the class directly beneath it to do the conversion job

Dear pd4ml’s staff,

I can see there are many successful case to use pd4ml. I am looking for Java library that converting html to pdf. But what we plan to do is to have the PDF in the server as an intermediate product (in form of byte stream or solid file) and then send the data to a network printer for print out.

I wonder someone can point me out how can I achieve it (by providing a URL, then save it as byte [] or byte stream)?

For the header and footer content, I suppose it should mean they are appear on every page. But do they have height limitation?

Kindly look forward to see your rapid response.
