Hi Matthias,
thanks for your help... a friend of mine also recommended FOP in
between. I took a look at the api but it seems to me that FOP uses XML
to generate a PDF? !
--> So how can I convert my jsf page into the required FOP-input
format?? I could not find any docu to fop (except some broken links...) ?
regards,
Hans

Hansjoerg,
we have worked with Apache FOP for creating pdfs. iText or
JasperReports are also lib that help you on that task.
inside of your backing bean method (referenced by a commandLink or
cmdButton) you can do somthing like this:
public String pdf() {
FacesContext ctx = FacesContext.getCurrentInstance();
if(!ctx.getResponseComplete()) {
HttpServletResponse response = (HttpServletResponse)
ctx.getExternalContext().getResponse();
byte[] file = //do some FOP, or ... stuff;
response.setContentType("application/pdf");
response.setHeader("Content-Disposition", "inline;
filename=\"foo.pdf\"");
response.setContentLength(file.length);
OutputStream out = response.getOutputStream();
out.write(file, 0, file.length);
out.flush();
out.close();
ctx.responseComplete();
return null;
}
This will work in p(l)ain servlet or struts world too (expect of the
usage of jsf api (like FacesContext))
However, the *magic* here is the responseComplete()
<from_java_doc>
Signal the JavaServer Faces implementation that the HTTP response for
this request has already been generated (such as an HTTP redirect),
and that the request processing lifecycle should be terminated as soon
as the current phase is completed.
</from_java_doc>
and yes... it's getResponseComplete() instead of isResponseComplete()
HTH,
Matthias
