AW: Problems displaying a PDF from stream

[Stefan Lindner]

Do you want to open the PDF in a separate window? Klick on some button and open 
a new browser window with pdf?

Betreff: Problems displaying a PDF from stream

While trying to display a PDF document from stream following problems
arrise:
IE7:
Resource can not be displaied at all.

Firefox 3.6.12:
PDF is displaied but if Chronk is cleared in Firefox while document is open 
then it cannot be displaied again. It is possible only after restarting Firefox.

No errors in log.

The code:
public class PdfGen extends WebResource {

    public PdfGen() {
        setCacheable(false);
    }

    @Override
    public IResourceStream getResourceStream() {
        IResourceStream resourceStream = new AbstractResourceStreamWriter() {
            private static final long serialVersionUID = 1934248394380163944L;
            public void write(OutputStream output) {
                testItextDirect(output);
            }
            public String getContentType() {
                return "application/pdf";
            }
        };
        return resourceStream;
    }

    private void testItextDirect(OutputStream output){
        try {
            Document document = new Document();
            PdfWriter.getInstance(document, output);
            document.open();
            document.add(new Paragraph("Hello World"));
            document.add(new Paragraph(new Date().toString()));
            document.close();
        } catch (DocumentException de) {
            try {
                throw new IOException(de.getMessage());
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}


in the init() of AuthenticatedWebApplication SharedResource added like this:
getSharedResources().add("pdfGen", new PdfGen());

Any help would be highly appreciated
Alex
