I am using FOP to create a PDF dynamically based on user input into a web
form. I don't have a problem creating the PDF only with the display of it.
I need that PDF to be immediately sent to the user via a redirect or
download. so something like this ....
@Override
public void onClick(){
validateUserDataFromForm();
if(!hasErrorMessage()){
ByteArrayOutputStream pdfData =
factory.createPDF(startDateThatIsSetViaTheForm, endDateThatIsSetViaTheForm,
reportType);
// Output the steam to a page I can redirect to.
// I can use a File if ByteArrayOutputStream is making things tough.
// I am fine if the user gets prompted like a download link, but I want
a single click to create and prompt for download.
}
}
.... Here is what I have tried.
1) Making the PDF a resource: This worked initially as I needed it to, but
I was having problems with the resource being reused and while the report
needed to vary on each generation. Basically, I need to create the PDF,
give it to the user, and then destroy the copy on the server. Every time
the user clicks the create button a new PDF needs to be built and sent to
the user. I also don't like this option as I don't want to waste memory by
adding too many resources that are not re-used. I need the user data to
update the display of the PDF when it is built, so I need the link to pass
in new values to the createPDF function every time.
2) Something like this...
final Response response = getRequestCycle().getResponse();
response.setContentType("application/pdf");
response.setContentLength(pdfout.size());
try{
OutputStream stream = response.getOutputStream();
stream.write(pdfData.toByteArray());
stream.flush();
}catch(Exception ex){
throw new RuntimeException(ex);
}
That results in an error like so...
[org.apache.wicket.protocol.http.WicketFilter] - closing the buffer error...
Any help would be appreciated! Thanks!
