Open PDF in a new window
Hello,
I am trying to open this pdf in a new window with no sucess.
protected void onSubmit()
{
final ByteArrayOutputStream pdfout = PDFHelper.genPDF();
final Response response = getRequestCycle().getResponse();
response.setContentType("application/pdf");
response.setContentLength(pdfout.size());
getRequestCycle().setRequestTarget(new IRequestTarget();
{
public void detach(RequestCycle requestCycle) { }
public void respond(RequestCycle requestCycle)
{
try
{
OutputStream stream = response.getOutputStream();
stream.write(pdfout.toByteArray());
stream.flush();
pdfout.close();
}
catch(IOException ex)
.....
I am totally new to wicket (and java) and could really use some help with
this.
Thanks

RE: Open PDF in a new window
Posted by Fred <Sm...@hotmail.com>.
Thanks,
Yes I tried that example (and didnt want to hijack that thread) originally and could not get it to work at all, so I went down this road.
Can you help me to get that example to work? This is what I tried:
protected void onSubmit()
{
downloadPdf(getRequestCycle(), pdfReq);
...
public void downloadPdf(RequestCycle requestCycle, PDFRequest pdfReq)
{
//returns stamped pdf as a ByteArrayOutputStream
ByteArrayOutputStream pdfout = PDFgenerate.generatePDF(pdfReq);
final String pdfToString = pdfout.toString();
final WebResponse webResponse = (WebResponse) requestCycle.getResponse();
webResponse.setContentType("APPLICATION/PDF");
webResponse.setHeader("Content-Disposition", "inline; filename=\"" + "test.pdf" + "\"");
requestCycle.setRequestTarget(new IRequestTarget() {
public void respond(RequestCycle requestCycle) {
try {
OutputStream stream = webResponse.getOutputStream();
OutputStreamWriter writer = new OutputStreamWriter(stream, "ISO-8859-1");
writer.write("hellooooooo");
writer.flush();
writer.close();
} catch (IOException ex) {
ex.printStackTrace();
}
}
public void detach(RequestCycle requestCycle) {
}
});
When I try the above the pdf does not render and I get the error:
File does not begin with '%PDF-'
