Hi Amedeo -
Thanks for the code. I compared your code to mine and
they are the same. Now when I go to the output page I
get the following displayed:
%PDF-1.3 %????????? 2 0 obj << /Length 4 0 R /Filter
/FlateDecode >> stream
x??}[?\???;~E?l ;<??2???$?=#???"?B?E?v??????? ?8????Y-?U????H
3?D? ????e? ??;?N?????uxwx??q??p??7;??6??&4{??K???#_l?\??2ke ??[&?

bC?|J??x????X???#*+i?&Mr(ld?Y<???????L?b????v??bF?iV?[Z???-5?V7?d?? ??}
?\?? ..........
This is just the first couple of lines. When viewing
the source of the page it is the same as what is
displayed on the page. There is no html header
information in the source. Is this ok?
Here is my code for the output page:
_pdfData and _fileName are being set on the previous
page
public class PDFViewer extends WOComponent {
private NSData _pdfData;
private String _fileName;
public PDFViewer(WOContext context) {
super(context);
}
public void setPdfData(NSData newPDFData) {
_pdfData = newPDFData;
}
public NSData pdfData() {
return _pdfData;
}
public void setFileName(String aFileName) {
_fileName = aFileName;
}
public String fileName() {
return _fileName;
}
public void appendToResponse(WOResponse aResponse,
WOContext arg1) {
super.appendToResponse(aResponse, arg1);
if (pdfData() != null) {
aResponse.disableClientCaching();
aResponse.removeHeadersForKey("Cache-Control");
aResponse.removeHeadersForKey("pragma");
aResponse.setHeader("application/pdf",
"content-type");
aResponse.setHeader("inline; attachment;
filename=\""+fileName()+"\"", "content-disposition");
aResponse.setHeader(Integer.toString(pdfData().length()),
"content-length");
aResponse.setContent(pdfData());
}
}
}
Thanks for the help.
