Wicket/Jackrabbit stream PDF file to client

[Stefan Droog <sd...@educator.eu>]

I want to send e.g. a PDF file to the client. It does work for JPG and Html but not for e.g PDF / PNG / TXT files.

When I try to open the file I get Adobe Reader could not open FILENAME because it is either not a supported file type or because the file has been damaged(for example, it was sent as an email attachment and wasn't correctly decoded).

Content type is "application/pdf".

Regards,
Stefan

Store the data in jackrabbit:
....
FileUpload upload = fileUploadField.getFileUpload();
Node resNode = fileNode.addNode("jcr:content", "nt:resource");
resNode.setProperty("jcr:data", upload.getInputStream());
resNode.setProperty("jcr:mimeType", upload.getContentType());
....

Stream data

Link:

Link exportCsv = new Link("downloadLink") {

                @Override
                public void onClick() {
                                IResourceStream stream = getResourceStream();

                                getRequestCycle().setRequestTarget(new ResourceStreamRequestTarget(stream).setFileName(m_fileName));
}
};
add(exportCsv);

getResourceStream returns stream

IResourceStream stream = new AbstractResourceStream() {
private InputStream m_in;
                private String m_mime;

                @Override
                public void close() throws IOException {
                                m_in.close();
                }

                @Override
                public InputStream getInputStream() throws ResourceStreamNotFoundException {
                                Session session = null;
                                try {
                                                .....
                                                //Get the inputstream from Jackrabbit repository
                                                m_in = content.getProperty("jcr:data").getStream();
                                                m_mime = content.getProperty("jcr:mimeType").getString();
                                } catch (Some exceptions)
                                } finally {
                                                session.logout();
                                }

                                return m_in;
                }

                @Override
                public String getContentType() {
                                return m_mime;
                }
};
