Hello Jörg,

I get an exception when invoking PDF.ok() in my Controller with Play version 2.1 and Play-pdf version 0.4.1.
Google indicates an issue between iText and Flying Saucer like here:
http://grails.1312388.n4.nabble.com/Grails-Rendering-Plugin-error-java-lang-NoSuchMethodError-com-lowagie-text-pdf-BaseFont-getCharBBox--td4525995.html

I appreciate any help or indications for a helpful source.
Thanks a lot!

Build.scala:
"pdf" % "pdf_2.10" % "0.4.1",

resolvers += Resolver.url("Violas Play Modules", url("http://www.joergviola.de/releases/"))(Resolver.ivyStylePatterns)

Below is my exception:

Hi,

I'm having a hard time getting my styles to show on the generated PDF.

I've tried specifying the path using "@routes" as well as using the classpath:

<link rel="stylesheet" type="text/css" href="@routes.Assets.at("css/pdf.css")" media="screen" />

OR

<link rel="stylesheet" type="text/css" href="/public/css/pdf.css" media="screen" />

My stylesheet only contains one declaration:

td {
color: blue;
}

However, my PDF comes up with no styles applied. All text is black. Also tried changing background color and other properties.

Please let me know if you need more information. I really like the way this module integrates with Play! but I need styles to work for my client. Thanks!

Like I posted on your blog, this module is not ready for play 2.2.0
To make it usable on play 2.2.0
just edit your plugins.sbt:
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.2.0")

and your build.properties:
sbt.version=0.13.0

I have testet it locally with some simple prints, seems all to be working fine,
greets an thanks for your work ...

I have testet some simple Prints, seems all to be fine...

Hi,

I can't use any color styling through css rendered in pdf.

I triedusing style attribute and class attribute with class defined in embedded style element, external stylesheet - on different kind of elements, div, span, p, table, etc.

No way.

Thanks a lot !

Maybe switch to https://github.com/typesafehub/config or use dependency injection.

Scala 2.10 is out and Play 2.1 is at RC2 with release imminent.

Play PDF plugin support for the latest and greatest would be nice ;-)

Hi,

i have inserted an tag. In develop mode their is no problem. the images is shown all the time.
But in production mode, the images is not shown. And it dows not have effect to use an hosted image on another server. Same with @routes.Assets("images/....jpg")

Don´t know where the problem is.

I am using IntelliJ and sbt to create a dist.

I've added the appropriate lines to my Build.scala file;

val appDependencies = Seq(
  "pdf" % "pdf_2.9.1" % "0.2"
)   

val main = PlayProject(appName, appVersion, appDependencies, mainLang = JAVA).settings(
  resolvers += Resolver.url("My GitHub Play Repository", url("http://www.joergviola.de/releases/"))(Resolver.ivyStylePatterns)
)   

But when I restart play, I get some unresolved dependencies. Is this something I can work around?

Is there a way to manage pages support using html (or any other way)?

i.e. is it possible to say, this markup goes in page 1, this other markup on page 2, etc?

Thank you
Gonzalo

Hi,
First, thank you for this module, that's a nice job (even if I could not make it work for now).
The module package is util.pdf.PDF which is not a very good idea since there already is a util._ package with Scala (or Java).

I would thus recommend you to use something like de.joergviola.play20-pdf.pdf.PDF instead. This would avoid confusion.

For example, at some place in my code, I use the util.Random classes provided by Scala, which was not working anymore because of course there was no Random in the PDF util package.

Cheers and thanks

If I render the template as html I can render an image with the src attribute pointing to another server on my machine, i.e.

<img src="http://localhost/<path-to-file>/<filename> />

But if I render the PDF with PDF.ok(), I get the error pasted below and a 0 byte document. Using the class path in the src attribute works fine, but in my use case I have to get the images from another server outside of Play!

The documentation seems to indicate that it should be able to load images with an http request, but it doesn't appear to be working.

Hi!

When application build by command: play dist, and run it, server response with main.css from module instead from my application.

How to tell play that it response with my main.css?

(Sorry for my english)

As stated in issue #19, /conf/fonts directory must exist in order to avoid NullPointerException while rendering PDF. This can be fixed with simple check for folder existance. Anyway this issue has other consequences. PDF modules reads fonts directly from filesystem using Java API. This works flawlessly in dev mode using "play run", but if you publish your application to standalone package using "play dist", PDF module is not working anymore. When you create production-ready standalone package, the whole application is merged into the JAR file and every resource must be read through the classloader. Long story short, files are not available through the filesystem calls as desired folders do not exist any more. PDF module than results in NullPointerException every time because it is not able to find folder /conf/fonts. Actually, the feature for auto-loading fonts is unusable at all. The only way to load desired fonts is to use CSS and fetch fonts through the public assets directly from Play application.

i just tried but I can not access the repo at http://www.joergviola.de/releases. Is this project still alive?

Hi, it sounds that since an element in the XHTML template has an "id" attribute, the PDF generation fails:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Since I remove the "id" attribute, it works out finely. The XHTML template above is valid given http://validator.w3.org/check

Any chances?

There is zero documentation out there for how to install Play 2.0 modules. Some individual modules have installation instructions shown on their github page. This one does not. Help please!

Hi,

The mandatory lookup of the directory /conf/fonts while setting up flying saucer should be optional.

If the user hasn't any specific fonts to add that only results in an empty folder created only to prevent runtime exception.

Thanks a lot !
