Hi Sunrita,
I note you've not yet received a reply to your questions. Please can you
supply the FO File together with the errors observed as I'm not sure I
follow the question about the image URL. Also can you paste the actual
warning messages you get so we can advise you precisely as to cause and
possible solution together with your fop.xconf file. Otherwise we'll
just be guessing.
Thanks,
Chris

Hi,
I am struggling to show images and data in PDF within a web application.
I could make the stand alone work easily. But in web it fails to get
the images.
I have tried the following:
Approach 1: [Here i tried using the ServletContextURIResolver to
resolve the images]
URIResolver uriResolver = new ServletContextURIResolver(servletContext);
DefaultConfigurationBuilder cfgBuilder = new
DefaultConfigurationBuilder();
Configuration cfg
= cfgBuilder.build(GeneratePDFWithFOP.class.getResourceAsStream("/fop.xconf"));
ResourceResolver resolver = new ResourceResolver() {
public OutputStream getOutputStream (
URI uri)
throws IOException {
URL url = servletContext.getResource(uri.toASCIIString());
return url.openConnection().getOutputStream();
}
public Resource getResource (
URI uri)
throws IOException {
return new
Resource(servletContext.getResourceAsStream(uri.toASCIIString()));
}
};
FopFactoryBuilder builder = new FopFactoryBuilder(new
File(".").toURI(), resolver).setConfiguration(cfg);
final FopFactory fopFactory = builder.build();
In the xsl for images I have put:
<fo:external-graphic content-height="0.32in" scaling="non-uniform"
content-width="0.30in" src="url(servletcontext: /arrow-pdf-header.png)" />
But this doesn't load the images.
SAX error show invalid URI for image. Though the same is accessible
via browser
Approach 2: [Here i used the Local path, so the images are coming
through but the data is not getting printed]
String appPath = servletContext.getRealPath("");
Configuration cfg = cfgBuilder.buildFromFile(new
File(appPath+"/WEB-INF/classes/fop.xconf"));
FopFactoryBuilder builder = new FopFactoryBuilder(new
File(appPath).toURI()).setConfiguration(cfg);
final FopFactory fopFactory = builder.build();
In the xsl for images i have put:
<fo:external-graphic scaling="non-uniform" content-height="0.40625in"
content-width="0.40625in" src="url(/arrow-pdf-header.png)" />
Though this one loads the images, the data fails to show up!. I also
get a few warning in the console such as table width was adjusted, and
few fonts were not found.
Thanks,
Sunrita
