Re: How to show PDF file in jsp page II.
Hi,
your PDF file has to be accessible for tomcat, for example:
Imagine your web application is stored under
%TOMCAT_ROOT%/webapps/yourapp
Then your PDF file has to be somewhere in your 'yourapp'
directory. It is the same as html pages: you referene them
(e.g. in html) with - relative path.
So this link in http://localhost/bla.html will link to
http://localhost/foo.html.
Try this: put your PDF file under your webapp-root (called
'yourapp' above...) directory. And in your jsp:
response.setRedirect(outPDF);
// outPDF is "TMP.PDF" (without c:)
// tomcat will look for 'yourapp/TMP.PDF'
// If your JSP is e.g. accessible under http://localhost/myjsp.jsp
// it will redirect to http://localhost/TMP.PDF which is also
// remote accessible (if read access is permitted)
I never tried response.setRedirect(), but I think this will work ;-)

I have Tomcat and browser on one PC . Doesn't the browser thus open the PDF
file directly, bypassing Tomcat ?
If so, I think I should use URL as parameter. But how can I find out http
address from inside the servlet?
Thanks for any comments.

Looks too convolute to me. If you have already created pdf file on a disk, why
do you process it by hands instead of rely on a web server? Just redirect
browser to the file, that will emulate reading static pdf, which works okay
even in IE (well, at least if extension is pdf).
I mean
response.sendRedirect("/foo/bar.pdf");

Re: How to show PDF file in jsp page ?
Thanks to all, this code works ...
File inputFile = new File(pdfFile);
FileReader fr = new FileReader(inputFile);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
int ch;
while((ch = fr.read()) != -1) {
baos.write(ch);
}
byte[] content = baos.toByteArray();
response.setContentType("application/pdf");
response.setContentLength(content.length);
response.getOutputStream().write(content);
response.getOutputStream().flush();

RE: How to show PDF file in jsp page ?
Is the browser IE?
Try this: Add the parameter to GET query, so the URL will end with .pdf
like this: http://./getPdf.jsp?id=&dummy=.pdf

I successfully created PDF , but now I don't know how to make browser show
it like PDF (Acrobat is installed, when I open file directly in browser,
all is ok).
If I use this code:
File inputFile = new File(pdfFile);
FileReader fr = new FileReader(inputFile);
int c;
while( (c = in.read()) != -1)
out.write(c);
fr.close()
, it shows only
%PDF-1.3 %^?? 4 0 obj << /Type /Info /Producer (null) >> endobj 5 0 obj
<< /Length 518 /Filter [ /ASCII85Decode /FlateDecode ] >> stream

lku6;kXe'1hU0KY_)ImgG*1CNnEe%YAdYqXKst:k4#- ...
When I placed on JSP page this line
response.setContentType("application/pdf");
, the result is similar:
%PDF-1.3
%^??
4 0 obj
<< /Type /Info
/Producer (FOP 0.20.3) >>
endobj
5 0 obj
<< /Length 518 /Filter [ /ASCII85Decode /FlateDecode ]
>>
stream
...
What must I do, to make browser use Acrobat plugin ? Thanks.
