Need help with Wicket, ResourceStream (itext adn pdf)

Hi,
I've been struggling to understand the concept of sending resources (such as
PDF) to the output with Wicket.
I searched many site and wasn't able to find anything useful for me.
(I found only one thread in this mailing list regarding iText).

Anyway,
Suppose I know how to create a PDF file.
How can I then show it to the user?

Suppose I have created the Document. What next?

If someone can give a direction in here or a link to good example, I would
be most appreciate.

Thanks

If what you want is streaming back the PDF contents something like:

ResourceLink fileLink  = new ResourceLink("file", new
DynamicWebResource(file.getName()) {

            private static final long serialVersionUID = 1L;

            @Override
            protected ResourceState getResourceState() {
                return new DynamicWebResource.ResourceState() {
                    @Override
                    public String getContentType() {
                        return DownLoadExportPanel.this.getContentType();
                    }

                    @Override
                    public byte[] getData() {
                        try {
                            return FileUtils.bytes(new
FileInputStream(file));
                        } catch (Exception e) {
                            return null;
                        }
                    }
                };
            }
        });

<a wicket:id="file"><span wicket:id="message"></span></a>

will do the Job. Here I'm assuming the PDF is in a file...

2- If what you want is showing the PDF inside an iframe maybe the following
link can be of some help
