Hi to all
I'm using Flying Saucer, via the grails pdf plugin
i don't know why, because in the last days i did many thing about how
i use css and i tried to update the pdf plugin of grails (that use
Flying Saucer), but now Flying Saucer is ignoring CSS
Both css embedded and linked, and i really don't know why

here the code of the service of the plugin:

byte[] buildPdfFromFile(url) {

ByteArrayOutputStream baos = new ByteArrayOutputStream();

ITextRenderer renderer = new ITextRenderer();
try {
renderer.setDocument(url);
renderer.layout();
renderer.createPDF(baos);
byte[] b = baos.toByteArray();
return b
}
catch (Throwable e) {
log.error e
}
}

here how I call it

def baseUri = request.scheme + "://" + request.serverName + ":" +
request.serverPort + grailsAttributes.getApplicationUri(request)
def tmpDirectory = System.getenv("TMP")
def urlFile = tmpDirectory + File.separator + params.id + ".html"
def fileName = params.filename ?: params.id + ".pdf"
String testo = new File(urlFile).text
byte[] b
b = pdfService.buildPdfFromString(testo, baseUri)
response.setContentType("application/pdf")
response.setHeader("Content-disposition", "attachment; filename=" +
fileName)
response.setContentLength(b.length)
response.getOutputStream().write(b)

in the urlFile there will be a HTML file like this one (I tried also
with embedded and liked css) but the css is totally ignored... i can
see images (so the base uri is correct) but no the css... i tryed also
with absolute url (for the liked css) but nothing
can someone help?

You could try turning on FS logging (XRLog.setLoggingEnable(true) from
Java or via the xr.util-logging.loggingEnable system property). The
symptoms you describe are normally the result of using the wrong UA
plugin, but that doesn't look to be the case here.

I try enabling the loggin this is what i get if i have no css inside

XRLog.isLoggingEnabled()true
org.xhtmlrenderer.render INFO:: Using CSS implementation from:
org.xhtmlrenderer.context.StyleReference
org.xhtmlrenderer.load INFO:: SAX XMLReader in use (parser):
com.sun.org.apache.xerces.internal.parsers.SAXParser
org.xhtmlrenderer.load INFO:: Loaded document in ~15ms
org.xhtmlrenderer.load INFO:: TIME: parse stylesheets 0ms
org.xhtmlrenderer.match INFO:: media = print
org.xhtmlrenderer.match INFO:: Matcher created with 118 selectors

so 0ms for styleshert parsing and this is ok, i have no css

if in the html file i have

i get similar output (0ms for css parsing)

if i try more css, linked, like this
<link rel="stylesheet" type="text/css" href="$
{resource(base:Utility.getCssPath(), file: 'main.css')}" media="all"/>
<link rel="stylesheet" type="text/css" href="$
{resource(base:Utility.getCssPath(), file: 'main_stampa.css')}"
media="print"/>
<link rel="stylesheet" type="text/css" href="$
{resource(base:Utility.getCssPath(), file: 'main_screen.css')}"
media="screen"/>
<link rel="stylesheet" type="text/css" href="$
{resource(base:Utility.getCssPath(), file: 'landscape.css')}"
media="print"/>
i get the same output, always 0ms for css parsing

why?

I tried clening cache (browser and server) and now, with some more css
linked, i get
org.xhtmlrenderer.load INFO:: TIME: parse stylesheets 79ms
but the pdf is like without css... :-(

Make sure you're setting media="all" or media="print" on your <style> tag.

Just found the problem... it was bauce the html page was without the
"doctype"
argh...
now is working...

but is not work the
table{
border-collapse:collapse;
}

the border collapse id working good in the browser... but the boarder
are not collapsed in the pdf (and the border collapse properties is a
css with media type print AND media type screen)

border-collapse: collapse isn't supported with -fs-table-paginate:
paginate. Is that the problem?

Not really, I'm afraid. :-( The closest to a workaround is probably
to set border-spacing to zero and halve the relevant border-width
settings.
