Re: How to show pdf ByteArrayResouce in browser
Thanks for the reply... I was able to render the pdf in browser with the
following piece of code:
ResourceStreamRequestTarget target = new ResourceStreamRequestTarget(null){
@Override
public void detach(RequestCycle requestCycle) {
// TODO Auto-generated method stub
}
@Override
public void respond(RequestCycle requestCycle) {
try{
OutputStream out =
requestCycle.getResponse().getOutputStream();
out.write(stream.toByteArray());
out.flush();
stream.close();
}
catch(Exception e){
e.printStackTrace();
}
}
};
getRequestCycle().setRequestTarget(target.setFileName("eFile.pdf"));
But now the problem is that the file name I set in the last line doesnot
work. It renders as
.pdf
Any suggestions??? Thanks

How to show pdf ByteArrayResouce in browser
I have class which generates pdf report. The report is generated as stream as
I donot want to save the file in server. I need to show the pdf in the
browser. But the link provided to this dynamically generated pdf opens a new
window and asks for saving the file. How to open the pdf in new window?
My piece of code:
IResourceStream stream1 = new ByteArrayResource("application/pdf",
stream.toByteArray()).getResourceStream();
getRequestCycle().setRequestTarget(new
ResourceStreamRequestTarget(stream1).setFileName("eFile.pdf"));
The stream here is the stream to which the pdf is written. I also tried the
following code. But this gives null pointer exception
getRequestCycle().setRequestTarget(new RedirectRequestTarget(urlFor(new
ResourceStreamRequestTarget(stream1).setFileName("eFile.pdf")).toString()));
Any help will be great. Thanks in advance.
