#26418
Hello,
I am tring to get a PDF report from a java web project. I am using eclipse helios tomcat server 7.0.
What I am tring to do is getting a html report as pdf. The jsp taglib seems great but i have a problem at Turkish chars (they don’t shown right at pdf reports).
I have downloaded pd4ml.pro.trial.361b1.zip and added the taglib project to eclipse.
But the jsp file doesn’t give me a correct chars.
<%@ taglib uri="http://pd4ml.com/tlds/pd4ml/2.6" prefix="pd4ml"%><br /> <%@page contentType="text/html; charset=UTF-8"%><br /> <pd4ml:transform screenWidth="400" pageFormat="A5"<br /> pageOrientation="landscape" pageInsets="100,100,100,100,points"<br /> enableImageSplit="false"><br /> <br /> <html><br /> <head><br /> <title>pd4ml test</title><br /> <style type="text/css"><br /> body {<br /> color: #000000;<br /> background-color: #FFFFFF;<br /> font-family: Tahoma, "Sans-Serif";<br /> font-size: 10pt;<br /> }<br /> </style><br /> </head><br /> <body><br /> <br /> Hello, World! ıüöİÖÜŞşÇç<br /> <br /> <pd4ml:page.break /><br /> <br /> Hello, New Page!<br /> <br /> </body><br /> </html><br /> </pd4ml:transform><br />
Any help would be great.#26419Hello PD4ML Support Team,
I am using the below posted code to generate PD4ML from asp.net application. Every thing till the file creation process works fine except it is throwing a permissions error when application tried to save the PDF. I am an admin on my Box. Can you help me to solve the permissions issue please?
Same time Can you also validate the stuff that I am doing below is proper as well.
{I did use VB.NET with framework 3.5 and PD4ML.NET during this task.Hope this helps}

Venky#27994Thanks. I was sure I had tried that, but I guess I must not have.
#27983Adrian,
PD4ML does not support
as, in most of the situations, there is no base to compute percentual heights, but width=”100%” should work.
> The second problem I have is that I have a html very large horizontally.
> Is there a way to stretch the html to fit a pdf page?Try to increase htmlWidth conversion parameter to exceed the table width.
#27360If an
tag has no height/width attributes, PD4ML uses the original pixel dimensions of the image.
If the image does not fit PDF page width, you need to adjust HTML-to-PDF scaling factor.
HTML->PDF conversion is performed in two steps: HTML rendering – it uses htmlWidth parameter (aka screenWidth in PD4ML JSP taglib) as virtual web browser frame width, and PDF output – it maps the htmlWidth to the horizontal width of choosen paper format.
If a particular image does not fit horizontally PDF page, that means, the image is wider than htmlWidth.
In the case you have two options:
- increase htmlWidth value (default is 640)
- scale down the image with height and width attributes of
tag
#27890Obviously in pd4fonts.properties there is a line
code2000=font.ttf
Just substitute it with
code2000=anotherfont.ttf
and make anotherfont.ttf exists and readable
#28085A HTML sample would help a lot to analyze the problem reasons.
Could you please attach it to a post or send it directly to support pd4ml com
#27599It depends on the server side session mechanism of you web application. You need to propagate the session ID correctly with the URL passed to PD4ML.
For the regular J2EE application a solution is to add the jsessionid parameter to URLs:
http://your.server.net/webapp/sourcepage.jsp;jsessionid=8764587625?param1=value1¶m2=value2
#26421Hello
I am using pd4ml.net to create dynamic pdfs.
When I am providing an output file to generatePDF method, i am getting permission denied error, if not i am getting the below error.
‘Unable to translate bytes [C7] at index -1 from specified code page to Unicode.’
I am trying to make it work since two weeks. looking for some assistance in this regard please.I greatly appreciate your help to make this working.
Thanks and Regards,
Venky#28080Oficially PD4ML does not support HTTPS, however on practice it tries to load HTTPS resources with Java’s standard SSL classes.
WebSphere and Weblogic, for example, and may be some others implement their own SSL libraries, not derived from Java’s standard one. As a result it causes ClassCastException. As I see, it is not your case, but there may be other SSL protocol related issues, specific for your environment.
The best workaround for the HTTPS issue is not to use HTTPS for CSS or image references. It is expensive from the performance perspective and causes undesired network transactions. A better approach is to reference the resources with relative links.
If your source HTML documents are read-only and you are not allowed to change HTTPS URLs there, there is also a solution with custom resource loaders. You may implement your own one and to use any SSL library you like:
pd4ml-html-css-pdf-tips-tricks-f7/a-definition-of-custom-resource-loaders-t40.html
Also http://pd4ml.com/examples.zip include source codes of SSL servlet, where you could borrow some ideas from (for example how to suppress a certificate check).
#27953Yes. I would recommend to use <pd4ml:page.header> for that:
[language=xml:3qj48yoa]
[/language:3qj48yoa]
, you mentioned, is a custom JSP tag, mapped to PD4ML API – so it works only in JSP container. More info about PD4ML headers/footers: html-pdf-faq-f1/pdf-page-headers-footers-definition-options-t41.html
