Re: [Flying Saucer Users] "java.io.IOException: Stream closed" when running Flying Saucer on a headless server

[Peter Brant]

FS isn't able to find a CSS file.  I believe in recent releases this is treated as a non-fatal error and you'll just get unstyled content.  You probably need to supply a base URL here:

renderer.setDocument(doc, null);

(instead of null).

I think FS assumes a default of the current directory.

Hi all, 

I need a little help with running Flying Saucer on a headless linux server.

I have a system that needs to convert html to .pdf files to send to customers on the fly. The HTML is created by my core application (not java) and saved as a file. It then calls a small java app, which turns it into the .pdf.

The app runs fine on my development machine but throws an error when I try to run it on the server. I suspect that the problem might be that I haven't set it up to run on the headless server, but I haven't been able to work out how to do that.

My source code (taken more or less directly from the "for Fun and Profit " tutorial) is as follows:

File htmlFile = new File(htmlFileName);
DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document doc = builder.parse(htmlFile); 

ITextRenderer renderer = new ITextRenderer();
renderer.setDocument(doc, null);
String outputFile = pdfFileName;
OutputStream os = new FileOutputStream(outputFile);
renderer.layout();
renderer.createPDF(os);
os.close();

and I am receiving the following error when I run it on the server:

java.io.IOException: Stream closed

I would appreciate it if anyone could help me get to the bottom of this.
