Hello,
well, embedding the component in a page shows not the PDF but the Java object
identity, e.g.
InlineViewingStreamResponse@8173c6
Maybe the error is somewhere else?
My component template is basically only ${showDocument()}.
Re: iframe - If I use an iframe for embedding a document viewer page, how do I
set the "src" parameter? I haven't found a more elegant way than
src="go\back\to\the\folder\containing\the\viewer".
Regards,
Daniel P.

Hi Daniel,
What exactly is the issue with your code? We use something similar (and content
type "application/pdf"); see below.
I'm sure you will take care of it when the code works, but your implementation
is extremely dangerous :-)
Best,
Thilo
public abstract class AbstractStreamResponse implements StreamResponse {
private String contentType;
private String filename;
public AbstractStreamResponse(String contentType)
{
this.contentType = contentType;
}
public void setFilename(String filename)
{
this.filename = filename;
}
@Override
public String getContentType()
{
return contentType;
}
@Override
public void prepareResponse(Response response)
{
if(!Strings.isNullOrEmpty(filename)) {
try {
String encodedFilename = URLEncoder.encode(filename, "UTF-8");
response.setHeader("Content-Disposition",
String.format("attachment; filename=%s", encodedFilename));
} catch (UnsupportedEncodingException e) {
// skip
}
}
}
}

Subject: AW: PDF Viewer component
Hi,
a little bit more information (read: code)...
I know the code is imperfect but this was just a quick and dirty setup to try
inline document viewing.
My Viewer component:
public class Viewer {
@Parameter(required=true)
@Property
String documentUrl;
@Inject
Logger logger;
public StreamResponse showDocument() {
if ("".equals(documentUrl)) {
return null;
}
File pdf = new File(documentUrl);
return new InlineViewingStreamResponse (pdf);
}
My StreamResponse implementation:
public class InlineViewingStreamResponse implements StreamResponse {
File file;
public FileAttachment(File file) throws FileNotFoundException {
if (file != null && file.exists() && file.isFile()) {
this.file = file;
} else {
throw new FileNotFoundException();
}
}
@Override
public String getContentType() {
try {
return Files.probeContentType(file.toPath());
} catch (IOException e) {
e.printStackTrace();
return null;
}
}
@Override
public InputStream getStream() throws IOException {
return new BufferedInputStream(new FileInputStream(file));
}
@Override
public void prepareResponse(Response response) {
response.setHeader("Content-Disposition", "inline; filename=" +
file.getName());
}
Regards,
Daniel P.
